PROCESS ENVISAGED The objective of the treatment is envisaged to be met with Biological Treatment to attain a high degree of efficacy. Sewage Waste Water Treatment units are designed keeping in view of the operational problems faced by the conventional waste water treatment system. These units are an ideal solution to the treatment of waste water in:-  Residential  Hotels  Health Resorts  Hostels  Restaurants  Auditorium  Hospitals (for treatment of domestic waste)  Industries (for treatment of domestic waste)

Dual Plumbing There will be a dual plumbing system for use of water for different applications thus saving on the quantity of fresh water. There will be two pipe lines, one supplying freshwater for drinking, cooking etc. And other for supply of recycled water for flushing, landscape irrigation, etc. this results in saving of fresh water demand and life of existing sewerage will be improved.

Collection of sewage The sewage generated shall be collected by gravity in the collection cum equalization tank located below the ground. Kitchen wastewater shall be put into general waste after passing through the grease interceptor. Air piping shall be provided in this tank for the mixing of sewage & to avoid anoxic conditions & the sedimentation of suspended impurities.

MOVING BED BIO REACTOR: BIO REACTOR The Bio Reactor is based on the Fluidized Random Aerobic Reactor which combines the advantage of Activated Sludge Plant with the Random distribution systems such as Bio filters. 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.

BACTERIAL GROWTH Bacteria grow rapidly in the Bio-Pac unit under properly engineered conditions. They consume organic chemical for their growth and remove them from the wastewater. The bacteria converts’ chemical into biological cells, which under proper growth conditions, form slims. Slims adhere to available surfaces and accumulate into what we call random biological film or fixed film. The high surface area-to-volume ratio of the units allows for

Environment Aplinka Solutions & Technologies Pvt. Ltd, Noida Uttar 2-16 Consultant Pradesh

Project Name Environment Clearance for Redevelopment of Residential Colony Project Proponent All India Institute of Medical Sciences EIA Project Address West Campus, Ansari Nagar, New Delhi accumulation of substantial concentration of bacteria in the relatively small reactor units. Further, the accumulated bacteria which provides high rates of removal or organic chemicals are fixed in the system and do not need to be recycled back to the basin. In the Bio Reactor system the water is constantly flowing through rigid PVC matrix to which the biological film attached. As the water flows past the biological film, bacteria in the film absorb organic chemicals as well as oxygen, nitrogen, phosphorus, and other trace nutrients required for their growth.

As the bacteria grow on the matrix and as more chemicals are added to the unit, the stationary biological film will continue to build in thickness. As the film becomes thicker the depth of penetration by diffusion of the absorbed material such as oxygen or other nutrients is not sufficient to reach the entire distance through the slime of the plastic media. At some point, the film will become sufficiently thick and portion of the film closest to the plastic media will not receive any food or nutrient, particularly oxygen. The inner layer of the film becomes anaerobic and the organisms lose their ability to adhere to the media surface. The shear forces of the water and / or air bubbles flowing through the matrix will ultimately become great enough to tear this portion of the biological film loose from the media. This process is called sloughing. The solids which slough from the media will flow out of the system with the effluents and are to be removed from the water through clarification in a settling module. The exposed portion of media surface will repeat the process of slime accumulation and sloughing. In actual operation of the Bio Reactor units, biological film will be in a state of dynamic, continuous growth and sloughing. At any given time, portion of the media are always at some point between forming a new film sloughing.

WORKING PRINCIPAL 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.

EFFLUENT QUALITY The effluent 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 effluent will depend substantially on the quantity of suspended solids and the concentration of soluble BOD entering the system. It is therefore necessary to provide means of separating the biological mass from the effluent. PACKAGE UNIT contains TUBE SETLLERS 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 0.40mm thickness. Environment Aplinka Solutions & Technologies Pvt.

CLARIFIER (TUBE SETTLER) The equalized and chemically treated effluent is pumped to this tank. This is a rectangular hopper bottom tank. The purpose of clarifier is to separate the dispersed and colloidal impurities by way of flocculation, coagulation and settling.The clarified supernatant overflows to the treated water storage tank and the sludge being heavier is drawn on towards the lagging end for further dewatering and disposal.

CLEAR WATER TANK In this tank, clear water is subjected to tertiary treatment for further polishing of effluent.

FILTRATION AND ADSORPTION COLUMN The clear effluent from the above tank is passed through Multigrade Filter Column & Activated Carbon Filter which serves the purpose of filtration as for undesirable suspended impurities as well as adsorb maximum dissolved impurities and color by activated carbon particles.

ULTRAFILTERATION After Multigrade Filter Column & Activated Carbon Filter water moves through Ultra filtration process which removes particulates and macromolecules from raw water, to produce potable water.

ULTRA VILOLET RADIATION TREATMENT Ultra violet radiation treatment works by exposing microorganisms. It disrupts the DNA of microorganisms and disables their ability to replicate i.e. it restricts the growth of microorganisms.

SCADA(Supervisory Control and Data Acquisition) i. INTRODUCTION  SCADA refers to a system that collects data from various sensors at a treatment plant, factory or in other remote locations and then sends this data to a central computer which then manages and controls the data.  SCADA systems are used not only in industrial processes: e.g. steel making, power generation (conventional and nuclear) and distribution, chemistry, but also in some experimental facilities such as nuclear fusion.  The size of such plants range from a few 1000 to several 10 thousands input/output (I/O) channels. However, SCADA systems evolve rapidly and are now penetrating the market of plants with a number of I/O channels.

ii. OBJECTIVE  Monitoring: Continuous monitoring of the parameters like pressure, pH, Turbidity, voltage, current etc.  Measurement: Measurement of variables for processing.  Data Acquisition: Frequent acquisition of data from RTUs and Data Loggers / Phasor data Concentrators (PDC).

 Data Communication: Transmission and receiving of large amounts of data from field to control centers.  Control: Online real time control for closed loop and open loop processes.  Automation: Automatic tasks of switching of transmission lines, CBs, etc.

iii. PRINCIPLE A SCADA system is destined to perform following tasks:  Data acquisition  Networked data communication  Data presentation  Control

These functions are performed by four kinds of SCADA components:  Sensors (either digital or analog) and control relays that directly interface with the managed system.  Remote telemetry units (RTUs), these are small computerized units deployed in the field at specific sites and locations. RTUs serve as local collection points for gathering reports from sensors and delivering commands to control relays.  SCADA master units, These are larger computer consoles that serve as the central processor for the SCADA system. Master units provide a human interface to the system and automatically regulate the managed system in response to sensor inputs.  Communications network that connects the SCADA master unit with RTUs in the field. iv. WORKING  Acquires quantitative measurements immediately and over time from a system/ plant.  Based on the collected data it Detects, Diagnoses and correct problems as soon as they arise.  Measures trends over time and prepares reports and charts based on the current and previous data.  Discovers and eliminates bottlenecks over time and improve efficiency.  All these above large and complex processes can be controlled with a few specialized staff.

v. FUNCTIONS The important functions of an SCADA are listed below  Data Acquisition  Information Display  Supervisory Control  Alarm Processing  Information Storage and Reports  Sequence of Event Acquisition  Data Calculation  Special RTU Processing/Control.
