SEWAGE TREATMENT TECHNOLOGY
Moving Bed Bioreactor Technology: Sewerage System
Prepared by: Vardan EnviroNet, Gurugram
Proposed Township at Village- Hatnoli, Tehsil- Khalapur, District- Raigad, Maharashtra, by M/s Jairamjiki Developments Ltd. Conceptual Plan
An external sewage network shall collect the sewage from all units, and flow by gravity to the proposed sewage treatment plant. Following are the benefits of providing the Sewage Treatment Plant in the present circumstances: Reduced net daily water requirements, source for Horticultural purposes by utilization of the treated waste water. Reduced dependence on the public utilities for water supply and sewerage systems. Sludge generated from the Sewage Treatment Plant shall be rich in organic content and an excellent fertilizer for horticultural purposes. a. Wastewater Details (a) Daily load : 3242 KLD (b) Duration of flow to STP : 20 hours (c) Temperature : Maximum 32oC (d) pH : 6.5 to 8.5 (e) Colour : Mild (f) T.S.S. (mg/l) : 150-300 mg/l
(g) BOD5 (mg/l) : 200-350 mg/l (h) COD (mg/l) : 500-600 mg/l b. Final discharge characteristics (a) pH : 6.5 to 8.5 (b) Oil & Grease : <10 mg/l (c) B.O.D. : <10 mg/l (d) C.O.D. : <60 mg/l (e) Total Suspended Solids : <10 mg/l c. Treatment Technology The sewage will be first passed through a Bar Screen Chamber where any extraneous matter would get trapped. The influent would overflow by gravity to the Oil & Grease Chamber which is provided for safety so that the oil may not inhibit the biological growth in the MBBR reactors.
The sewage would then collected in an Equalization Tank where the variations in flow and characteristics are dampened, which otherwise can lead to operational problems and moreover it allows a constant flow rate downstream. Here the sewage is kept in mixed condition by means of coarse air bubble diffusion.
The Bio Reactor is based on the Fluidized Random Aerobic Reactor which combines the advantage of an Activated Sludge Plant with the Random distribution systems such as Biofilter

Proposed Township at Village- Hatnoli, Tehsil- Khalapur, District- Raigad, Maharashtra, by M/s Jairamjiki Developments Ltd. Conceptual Plan with capacities that could be as low as 1/10th of ASP and fractional power consumption, such a reactor is ideal for the efficient removal of BOD and organics from the wastewater.
The tanks are packed with RIGID PP-UV-sterilized Gas Fluted Media with liquid random distribution wherein air diffusers are placed to uniformly release air across the tanks. Working Principle:
The MBBR works on the same principle as the submerged fixed film process with only one exception – the media is not fixed and floats around in the aeration tank. The main advantage of this system over the submerged fixed film process is that it prevents choking of the media. This also avoids sludge recirculation. Compared to conventional technologies the MBBR is compact, energy efficient and user friendly. It also allows flexibility in design of the reactor tank.
Figure-3: A figure showing the working principle of MBBR
Sewage Quality:
The Sewage discharged from the Bio reactor system will contain sloughed biological solids, but would be relatively free of soluble organic chemicals. The quantity of biological solids in the sewage will depend substantially on the quantity of suspended solids and the concentration of soluble BOD entering system. It is therefore necessary to provide means of separating the biological mass from the sewage. Package unit contains tube settlers for sedimentation and 60 Gross fluted Rigid PVC fill media for the FAB units to treat the wastewater for discharge into the receiving waters and/or the sanitary sewers as per the local regulations. The media thickness changes with the design parameters/depth of the unit and can vary from 0.25 to 0.40 mm thickness.

1. Tube Settler: Here we are providing the Tube Settler along with the PVC media which will enhance the contact period and thereby the improved performance. The Tube settler will have a determined lope in the bottom to collect the suspended solids from the waste water. The sludge will be suited to the Sludge Drying Beds.
2. Pressure Sand Filter: Here the treated water coming from the TSS will be treated for the suspended impurity removal.
3. Activated Carbon Filter: Here the water coming from the ACF will be treated for color removal, suspended impurity removal and the treated water shall be sent to the sewer.
4. Filter Press: A filter comprises a set of vertical, juxtaposed recessed plates, presses against each other by hydraulic jacks at one end of the set. The pressure applied to the joint face of each filtering plate must withstand the chamber internal pressure developed by the sludge pumping system. This vertical plate layout forms watertight filtration chambers allowing easy mechanization for the discharge of cakes. Filter clothes finely or tightly meshed are applied to the two grooved surfaces in this plat.
Primary Treatment: This is the first step of inlet waste mainly consist of removal of coarse particles, oil and grace and mixing co-agents in the water for removal of suspended solids through sedimentations. After this treatment scheme, the BOD, TSS, COD, and O&G level comes down to 20% of initial levels.
Secondary Treatment: This is second step of waste water treatment. It mainly consist aerobic process of the Primary treated water, bacterial growth, EM dosing addition of oxygen and chemical which help in bacterial growth and lastly settlement of the biological waste as sludge. Normally it is found that the reduction level in TSS, BOD, O & G and COD after an efficient secondary treatment will be as under-
Tertiary Treatment: This is the final stage of treatment where the Sewage after secondary treatment first is mixed with Sodium Hypo Chloride and then Sewage will be passed through (PSF) dual media filter and (ACF) activated carbon filter where sand, anthracite and activated carbon will be used as filtration media. Once the above limits achieved thereafter the final outlet water will also confirms the Bio Assay test of 90% of fish survive.

RAIN WATER HARVESTING
The storm water disposal system for the premises shall be self-sufficient to avoid any collection/stagnation and flooding of water. Storm water drainage plan of the project is enclosed. The amount of storm water run-off depends upon many factors such as intensity and duration of precipitation, characteristics of the tributary area and the time required for such flow to reach the drains. The drains shall be located near the carriage way along either side of the roads. Taking the advantage of road camber, the rainfall run off from roads shall flow towards the drains. Storm water from various plots/shall be connected to adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 98 rainwater harvesting pits at selected locations, which will catch the maximum run-off from the area. 1) Since the existing topography is congenial to surface disposal, a network of storm water pipe drains is planned adjacent to roads. All building roof water will be brought down through rain water pipes. 2) Proposed storm water system consists of pipe drain, catch basins and seepage pits at regular intervals for rain water harvesting and ground water recharging. 3) Peak Hourly rainfall of 1571 mm/hr shall be considered for designing the storm water drainage system. Rain water harvesting has been catered to and designed as per the guideline of CGWA. The ground water level in the area is 150 meters bgl. The bottom of the recharge structure will be kept 5 m above this level. At the bottom of the recharge well, a filter media is provided to avoid choking of the recharge bore. Design specifications of the rain water harvesting plan are as follows: Catchments/roofs would be accessible for regular cleaning. The roof will have smooth, hard and dense surface which is less likely to be damaged allowing release of material into the water. Roof painting has been avoided since most paints contain toxic substances and may peel off. All gutter ends will be fitted with a wire mesh screen and a first flush device would be installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags and paper pieces will get arrested by the mesh at the terrace outlet and to prevent contamination by ensuring that the runoff from the first 10-20 minutes of rainfall is flushed off. No sewage or wastewater would be admitted into the system. No wastewater from areas likely to have oil, grease, or other pollutants has been connected to the system.

1. Organic Waste
Organic waste, includes kitchen waste and garden waste generated from the dwelling units, will be treated by Organic waste compost machine on site. The compost is then used for landscaping on the site. The OWC machine will be placed at a designated area.
2. Type of Waste to be Treated
• Kitchen waste will be collected from units and lobbies of the Towers. This waste will be stored in garbage room which is located at the basement of the towers and further send to organic waste converter for treatment.
• Landscape waste is bio-degradable waste and will be composted in Organic waste converter. After post occupancy, horticulturist will collect garden waste and store in basement area, where organic waste converter is located. The treated organic waste will be used on site as manure for the landscape at the site.
3. Organic Waste Treatment System
OWC (Organic Waste Convertor) is an easy to use Decentralized Waste Management System to turn large amounts of organic waste such as kitchen waste, garden waste, food processing waste etc. into compost. The system is designed to eliminate odour and also to remove the problem of irritants such as flies and rats. The OWC is a bio-mechanical Composting System which consists of the OWC machine, Curing System and a number of optional accessories for specific waste challenges. The machine takes organic waste and Bioculum as input and to create manure starter. In just one week of curing the processed waste is transformed into manure that can be used on site in gardens or agriculture. 4. Process Description of Organic Waste Converter 4.1 Organic waste collection Prepared by: Vardan EnviroNet, Gurugram
Proposed Township at Village- Hatnoli, Tehsil- Khalapur, District- Raigad, Maharashtra, by M/s Jairamjiki Developments Ltd. Conceptual Plan
The organic waste from the kitchens in general contains food waste from the pre-cooking operation and post cooking remnant or excess food. Waste from garden containing pruning’s and small branches of the trees up to 2 cm diameter and/or bones, will be passed through the Shredder before it is placed into the container of the OWC. 4.2 Organic Waste Treatment Organic waste fed into OWC is mixed, aerated & fluidized and crushed for 5 minutes. Then container of the OWC is opened and observations are noted. If the crushed material has more moisture content which can be seen by visual observation, then absorbing media is added into the container up to 20% of the weight of the waste depending on the moisture content in the waste. The odour control powder “Bioculum” is added at the dosage rate of 1 gm of Bioculum/kg of waste. Then the lid of the container is closed and again the OWC is operated for 5 minutes. After the completion of 5 minutes, the system will give audio-video indication by a beep--beep sound and indication of light. The lid is then opened and the processed material is observed. If it is turned to granular free flowing material, then lid is closed and the system is restarted. The bottom valve is opened for draining of the material. The raw compost is collected in the trolley/crates placed underneath of OWC System. 4.3 Curing of Raw Compost For maturing and curing the raw compost, the material from the trolley is shifted in the crates which have perforation for aeration and then crates are placed in the curing system. Depending on the waste generation capacity, number of curing systems has to be proposed. Single Curing System has 100 kg/day capacity whereas Double Curing System has 200 kg/day capacity. After 10 days curing period, the compost from the tray can be used for application to the plants or any other mode of usage of manure in the agriculture.

Adjusting the settings and illumination levels to ensure minimum energy used for desired comfort levels.
Behavioral Change on Consumption Promoting resident awareness on energy conservation Training staff on methods of energy conservation and to be vigilant to such opportunities.
ENVIRONMENTAL MANAGEMENT SYSTEM AND MONITORING PLAN
For the effective and consistent functioning of the complex, an Environmental Management system (EMS) would be established at the site. The EMS would include the following: An Environmental management cell Environmental Monitoring. Personnel Training. Regular Environmental audits and Correction measures Documentation – standards operation procedures, Environment Management Plan etc
ENVIRONMENTAL MANAGEMENT CELL
Apart from having an Environmental Management Plan, it is also proposed to have a permanent organizational set up charged with the task of ensuring its effective implementation of mitigation measures and to conduct environmental monitoring. Hierarchical Structure of Environmental Management Cell: Normal activities of the EMP cell would be supervised by a dedicated person who will report to the site manager/coordinator of the residential plotted colony. The hierarchical structure of suggested Environmental Management Cell is given in following Figure-7.

ENVIRONMENTAL MONITORING
The purpose of environmental monitoring is to evaluate the effectiveness of implementation of Environmental Management Plan (EMP) by periodic monitoring. The important environmental parameters within the impact area are selected so that any adverse affects are detected and time action can be taken. The project proponent will monitor ambient air Quality, Ground Water Quality and Quantity, and Soil Quality in accordance with an approved monitoring schedule.

Noise: Day & Night level Noise Monitoring (Leqday, • Six Monthly Leqnight) Soil: • Soil Monitoring, Qualitative and quantitative • Six Monthly testing/analysis to check the soil fertility, porosity, texture, water holding opacity etc.
Awareness and Training: Training and human resource development is an important link to achieve sustainable operation of the facility and environment management. For successful functioning of the project, relevant EMP would be communicated to:
Residents and Contractors: Residents must be made aware of the importance of waste segregation and disposal, water and energy conservation. The awareness can be provided by periodic Integrated Society meetings. They would be informed of their duties.
Environmental Audits and Corrective Action Plans: To assess whether the implemented EMP is adequate, periodic environmental audits will be conducted by the project proponent’s Environmental division. These audits will be followed by Correction Action Plan (CAP) to correct various issues identified during the audits.
ENVIRONMENT MANAGEMENT PLAN
The Environment Management Plan (EMP) would consist of all mitigation measures for each component of the environment due to the activities increased during the construction and operational phase of the project and these are discussed in later subsections.
The EMP is generally
Prepared in accordance with the rules and requirements of the MoEF and CPCB/ SPCB
Prepared by: Vardan EnviroNet, Gurugram
Proposed Township at Village- Hatnoli, Tehsil- Khalapur, District- Raigad, Maharashtra, by M/s Jairamjiki Developments Ltd. Conceptual Plan
To ensure that the component of facilities are operated in accordance with the design A process that confirms proper operation through supervision and monitoring A system that addresses public complaints during construction and operation of the facilities and A plan that ensures remedial measures is implemented immediately.
The key benefits of the EMP are that it offers means of managing its environmental performance thereby allowing it to contribute to improved environmental quality. The other benefit includes cost control and improved relations with the stakeholders.
EMP includes four major elements:
Commitment & Policy: The management will strive to provide and implement the Environmental Management Plan that incorporates all issues related to air, water, land and noise. Planning: This includes identification of environmental impacts, legal requirements and setting environmental objectives. Implementation: This comprises of resources available to the developers, accountability of contractors, training of operational staff associated with environmental control facilities and documentation of measures to be taken. Measurement & Evaluation: This includes monitoring, counteractive actions and record keeping.
It is suggested that as part of the EMP, a monitoring committee would be formed by M/s Jai Ramjiki Developments Ltd. comprising of the site in-charge/ coordinator, environmental group representative and project implementation team representative. The committee’s role would be to ensure proper operation and management of the EMP including the regulatory compliance. The components of the environmental management plan, potential impacts arising, out of the project and remediation measures are summarized below in Table-15.

To mitigate the impacts of PM10 & PM2.5 during the construction phase of the project, the following measures are recommended for implementation: A dust control plan Procedural changes to construction activities
Dust Control Plan
The most cost-effective dust suppressant is water because water is easily available on construction site. Water can be applied using water trucks, handled sprayers and automatic sprinkler systems. Furthermore, incoming loads could be covered to avoid loss of material in transport, especially if material is transported off-site.
Procedural Changes to Construction Activities
Idle time reduction: Construction equipment is commonly left idle while the operators are on break or waiting for the completion of another task. Emission from idle equipment tends to be high, since catalytic converters cools down, thus reducing the efficiency of hydrocarbon and carbon monoxide oxidation. Existing idle control technologies comprises of power saving mode, which automatically off the engine at preset time and reduces emissions, without intervention from the operators.
Improved Maintenance: Significant emission reductions can be achieved through regular equipment maintenance. Contractors will be asked to provide maintenance records for their fleet as part of the contract bid, and at regular intervals throughout the life of the contract. Incentive provisions will be established to encourage contractors to comply with regular maintenance requirements.
Reduction of On-Site Construction Time: Rapid on-site construction would reduce the duration of traffic interference and therefore, will reduce emissions from traffic delay.

EMP FOR AIR ENVIRONMENT DURING OPERATION PHASE:
To mitigate the impacts of pollutants from DG set and vehicular traffic during the operational phase of the Colony, following measures are recommended for implementation:
DG set emission control measures Vehicular emission controls and alternatives Landscape development Diesel Generator Set Emission Control Measures
Adequate stack height will be maintained to disperse the air pollutants generated from the operation of DG set to dilute the pollutants concentration within the immediate vicinity. Hence, no additional emission control measures have been suggested.
Vehicle Emission Controls and Alternatives
During construction, vehicles will be properly maintained to reduce emission. As it is a residential plotted colony along with group housing, vehicles will be generally having “PUC” certificate. Footpaths and Pedestrian ways: Adequate footpaths and pedestrian ways would be provided at the site to encourage non-polluting methods of transportation.
Landscape Development
Tree plantation is one of the preferred methods to mitigate air and noise pollution. Plants serve as a sink for pollutants, act as a barrier to break the wind speed as well as allow the dust and other particulates to settle on the leaves. It also helps to reduce the noise level at large extent. Table given in green area indicates various species of the trees that can be used to act as a barrier.
EMP FOR NOISE ENVIRONMENT DURING CONSTRUCTION PHASE:
To mitigate the impacts of noise from construction equipment during the construction phase on the site, the following measures are recommended for implementation. Time of Operation: Noisy construction equipment would not be allowed to use.

Job Rotation and Hearing Protection: Workers employed in high noise areas will be employed on shift basis. Hearing protection such as earplugs/muffs will be provided to those working very close to the noise generating machinery.
EMP FOR NOISE ENVIRONMENT DURING OPERATION PHASE:
To mitigate the impacts of noise from diesel generator set during operational phase, the following measures are recommended:
Adoption of Noise emission control technologies Landscape development Noise Emission Control Technologies
It would be ensured that the manufacturer provides acoustic enclosure as an integral part along with the diesel generators set. Further, enclosure of the services area with 4 m high wall will reduce noise levels and ensure that noise is at a permissible limit for resident of the site and BLUE BINS surrounding receptors.
EMP FOR ECOLOGICAL ENVIRONMENT DURING CONSTRUCTION PHASE:
Construction activity changes the natural environment. But residential plotted colony also creates a built environment for its inhabitants. The project requires the implementation of following choices exclusively or in combination.
Restriction of construction activities to defined project areas, which are ecologically sensitive Restrictions on location of temporary labor tents and offices for project staff near the project area to avoid human induced secondary additional impacts on the flora and fauna species Cutting, uprooting, coppicing of trees or small trees if present in and around the project site for cooking, burning or heating purposes by the labors will be prohibited and suitable alternatives for this purpose will be made Along with the construction work, the peripheral landscape development with tree plantation would be developed with suggested native plant species, as they will grow to a full-fledged covered at the time of completion.

EMP FOR ECOLOGICAL ENVIRONMENT DURING OPERATION PHASE:
Improvement of the current ecology of the project site will entail the following measures:
Plantation and Landscaping Landscape development with tree plantation Park and Avenue Plantation
The section below summarizes the techniques to be applied to achieve the above objectives:
Plantation and landscaping
Selection of the plant species would be done on the basis of their adaptability to the existing geographical conditions and the vegetation composition of the forest type of the region earlier found or currently observed.
Tree plantation Plan
The plantation matrix adopted for the tree plantation includes pit of 0.3 m × 0.3 m size with a spacing of 2 m x 2 m. In addition, earth filling and manure may also be required for the proper nutritional balance and nourishment of the sapling. It is also recommended that the plantation has to be taken up randomly and the landscaping aspects could be taken into consideration.
Multi-layered plantation comprising of medium height trees (7 m to 10 m) and shrubs (5 m height) are for the landscape development with tree plantation. In addition creepers will be planted along the boundary wall to enhance its insulation capacity.
Selection of Plant Species for Tree Plantation
The selection of plant species for the development depends on various factors such as climate, elevation and soil. The plants would exhibit the following desirable characteristics in order to be selected for plantation
1. The species should be fast growing and providing optimum penetrability 2. The species should be wind-firm and deep rooted

3. The species should form a dense canopy 4. As far as possible, the species should be indigenous and locally available
5. Species tolerance to air pollutants like SO2 and NOx should be preferred 6. The species should be permeable to help create air turbulence and mixing within the belt 7. There should be no large gaps for the air to spill through 8. Trees with high foliage density, leaves with larger leaf area and hairy on both the surfaces 9. Ability to withstand conditions like inundation and drought 10. Soil improving plants (Nitrogen fixing rapidly decomposable leaf litter) 11. Attractive appearance with good flowering and fruit bearing 12. Bird and insect attracting tree species 13. Sustainable green cover with minimal maintenance.
Parks and Avenue Plantation
Parks and gardens maintained for recreational and ornamental purposes will not only improve the quality of existing ecology at the project site but also will improve the aesthetic value. Avenue Plantation
1. Trees with colonial canopy with attractive flowering 2. Trees with branching at 7 feet and above 3. Trees with medium spreading branches to avoid obstruction to the traffic 4. Fruit trees to be avoided because children may obstruct traffic and general movement of public.
