1.9 Sewage Treatment Process (SAF) SAF is an extremely efficient and well-proven biological treatment process which is used to biodegrade organic matter. It can also reduce nitrogen in the wastewater to deliver a treated wastewater that exhibits a very high level of BOD, COD and Nitrogen reduction along with high levels of reduction in suspended solids. The SAF could be described as a “box of media”. It utilizes a rigid, corrugated, structured polypropylene media to give a high surface area for biomass attachment. The media is arranged into cells-in-series where effluent is contacted with the fully submerged media in the presence of co-current aeration. Air is supplied by two low- maintenance regenerative blowers. Air enters the process below the media via fine bubble membrane diffusers. A secondary clarifier tank follows the SAF for removal of any biomass that sloughs off the media during operation. Biological phosphorus and nitrogen removal can be achieved with the SAF since the design incorporates sequential staged operations as required for BNR flow schemes. Phosphorus removal utilizes the anaerobic, balance tank (septic tank) used prior to the SAF. Recycled sludge from the final clarifier is mixed with the influent in this stage. Nitrogen removal is then achieved via denitrification in the first cell of the SAF where, with no air injected, and the introduction of recycled nitrified effluent from the end of the process, the process becomes anoxic. The latter SAF cells are fully aerated and BOD removal and nitrification are achieved in these. Full BNR requires a fourcell SAF, minimum. Typically effluent from a full BNR scheme will be: • BOD less than 10 mg/l • Total nitrogen less than 5 mg/l • Ammonia nitrogen less than 1 mg/l • Total phosphorus less than 0.5 mg/l Process: Raw sewage from the sewage pump station is pumped through the inlet works of the WWTP where it undergoes screening for removal of inorganics prior to entering the balance tank. The balance tank provides a buffer against peak inflows and provides a steady inflow to the downstream process. Prior to entering the treated effluent storage tank the effluent may be filtered (to achieve Class A quality). The treated effluent is stored in the irrigation tank prior to discharge to the irrigation field or re-use, whichever is applicable.

M/s Raheja Developers Ltd. Conceptual Plan 20 Modification and Expansion of Group Housing Project “Atharva Group Housing” At Sec-109, Village Pawala Khurupur, Gurugram, Haryana

Inlet Works All raw sewage is pumped to the inlet works of the waste water treatment plant. A mechanical screen is installed to remove all the inorganic material from the sewage and dispose it to the waste bin below. Balance Tank The Balance Tank is designed to handle peak flows and allow a pre-determined and controlled flow for subsequent treatment. The waste water is temporarily stored in the Balance Tank before being pumped by a submersible Balance Pump to Primary Tank 1. The flow rate is set using the flow control valves located in the Balance Tank. Excess flow is returned to the same tank. The Balance Tank level is regulated by 3 float-type level switches. A coagulant is dosed into the discharge of the Balance Pump by the Coagulant Dosing Pump whenever the Balance Pump runs. The coagulant assists both in aiding the settlement of settleable solids in the plant and in reducing the phosphorous level in the treated effluent. The Coagulant Dosing pump draws from a bunded carboy of coagulant.] Primary Tanks Primary Tank 1 provides additional buffer capacity of inlet flow whilst Primary Tank 2 creates a steady inflow for the Anoxic and the Aerobic Tanks. After the waste water is delivered to Primary Tank 1, the top water level of the influent waste water is allowed to overflow into Primary Tank 2. Both tanks encourage sedimentation of between 30 and 50% of the influent suspended solids and allow anaerobic digestion to take place. In anaerobic waste water treatment, bacteria digest organic material in the absence of oxygen and transform part of the sludge to gases such as methane and carbon dioxide. In this design, the anaerobic treatment occurs in Primary Tank 1 and Primary Tank 2. Anoxic Tank The top water level of the influent waste water is allowed to overflow from Primary Tank 2 to the Anoxic Tank. The Anoxic Tank allows nitrate-specific bacteria to use nitrate (NO3) as an oxygen source and a nutrient in a process called denitrification. This activity helps to remove nitrogen based pollutants such as urea and ammonia by converting them into nitrate and nitrite before releasing them as nitrogen gas into the atmosphere. The tank is enriched with returned activated sludge (RAS) from the Clarifier to provide a plentiful supply of food for the bacteria. The partially treated effluent from the Anoxic Tank contains approximately 65% of the pollution load of the original sewage influent entering the waste water plant. Aerobic Tank The top water level of the influent waste water is allowed to overflow from the Anoxic Tank to the Aerobic Tank where it is aerated. Air is introduced into the Aerobic Tank by the Biological Air Blower through air diffusers located beneath a submerged media. Coarse air bubbles provide favourable conditions for the growth of aerobic bacteria. The Aerobic Tank which contains the submerged media has a large surface area, allowing bacteria and other micro-organisms to thrive and form a biological film. These micro-organisms

M/s Raheja Developers Ltd. Conceptual Plan 21 Modification and Expansion of Group Housing Project “Atharva Group Housing” At Sec-109, Village Pawala Khurupur, Gurugram, Haryana utilise the dissolved oxygen in the air bubbles in the waste water to consume dissolved matter and by so doing remove a majority of the colloidal contaminants present in the waste water by converting them into carbon dioxide and biological floc. Floc is then allowed to settle in the Clarifier from where it is removed, thereby reducing the accumulation of sludge. Friction from the coarse air bubbles further serves to scour and release dead biomass from the media. This Aerobic Tank is partially divided by a baffle so as to prevent under-aerated waste water from prematurely moving to the next stage in the treatment process. This baffle also serves to alter the flow direction such that the partially treated waste water will make intimate contact with the submerged media before entering the Clarifier. Clarifier The Clarifier removes heavier solids by means of settlement and separation from the liquid phase. It is designed to have a large surface area with adequate retention time. The hopper bottom channels the sediment to the centre of the Clarifier tank before the sediment is returned to Primary Tank 1. Clear liquor from the top of the Clarifier is decanted into the Chlorine Contact Tank. In this process, clarification and thickening happen at the same time. Separation of solids from the liquid stream occurs to produce a clarified effluent with low suspended solid levels. From thickening, the conveyance of sludge particles to the bottom of the tank results in a slightly concentrated underflow, known as return activated sludge (RAS). Chlorine Contact The top water level of the influent waste water is allowed to overflow from the Clarifier to the Chlorine Contact Tank. The Chlorine Contact Tank contains chlorine in tablet form and it is designed to provide 30 minutes minimum contact time for effective disinfection of the influent with chlorine, a powerful disinfectant. This is a process whereby chlorine compounds are added to the treated waste water for the purpose of pathogen reduction. Calcium hypochlorite tablets are in constant contact with the effluent to ensure that the effluent is safe for disposal. Media Filter A media filter is required to meet the quality to re-use it again. Before reaching the Irrigation Tanks the effluent is filtered using a Media Filter which will remove particles above 10 microns in size. When the pressure drop across the Media Filter reaches a pre-determined set point the Media Filter is automatically backwashed by the Media Filter Backwash Pump which draws water from the Irrigation Tank with the dirty backwash wash water going back to the Balance Tank.

1.14 Green Area

Total green area measures 20,447 m2 i.e. 35.7 % of the net plot area is planned to be kept under green cover. At present, 17,385.1 sq. m. of area is already under green cover at site. Evergreen and native species are preferably planted at the project site. Native species are adapted to natural conditions and also requires less aftercare and maintenance. Trees with large & round canopy are planted. Plantation act as noise buffer and also provide surface for dust settlement. Green belt development plan for the area is given below.

Green Belt development Plan

All the developments are associated with the pollution of one or more environmental component. Plants are the natural sink of that pollution. Plants help in abatement of the pollution and restore the degraded environment. Green belt lowers down the air pollution by providing a surface to settle down or by absorbing the pollutants, attenuate noise level and uses the waste water. Phyto- remediation is one of the most successful available technologies of restoring the degraded environment. For this project area of 20,447 m2 is proposed to be put under green cover. Green cover will comprise of:

• A peripheral green belt • Avenue plantation (along road) • Lawns/parks & grass cretes/pavers • Planters

Selection of Plant Species for Green Belt Development

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

M/s Raheja Developers Ltd. Conceptual Plan 28 Modification and Expansion of Group Housing Project “Atharva Group Housing” At Sec-109, Village Pawala Khurupur, Gurugram, Haryana

1. Species should be fast growing and providing optimum penetrability with minimal maintenance. Perennial, evergreen & fast growing trees 2. Species should be wind-firm and deep rooted 3. Indigenous and locally available species will be planted 4. Trees with high foliage density, leaves with larger leaf area and hairy on both the surfaces. Round, thick & spreading canopy is preferred for peripheral green belt and oblong canopy for road side plantation 5. Ability to withstand conditions like inundation and drought 6. Soil improving plants (Nitrogen fixing rapidly decomposable leaf litter) 7. Bird and insect attracting tree species 8. Tolerant to climatic conditions of the area and with less water requirement & after care will

preferable be planted. Species tolerance to air pollutants like SO2 and NO2 should be preferred 9. Plantation trees with ornamental foliage & shrubs with fragrant flowers will enhance scenic beauty of the area. Attractive appearance with good flowering and fruit bearing 10. Plantation should be such that it maintains ecological & hydrological balance of the region. Trees and shrubs to be planted at project site as per CPCB guidelines for green belt development are given below in Table 15 below
