Wastewater collection and conveyance system shall be an underground drainage network that is designed to collect wastewater from the entire premises and convey at Sewage Treatment Plant of capacity 160 KLD to be located within the premises. The sewage is considerably rich in organic content; it is best treated with aerobic process. Various biological reactors are available like Conventional Aeration system, Extended Aeration M/s Comely Buildtech India Pvt. Ltd. 11

12 (EA), Diffused aeration, Submerged Aerobic Fixed Film reactor (SAFF), Moving Bed Bio Reactor (MBBR), and Fluidized Aerobic Bio-Reactor (FAB.) The selection is made based on ease of operation for the kind of sewage intake. Fluidized Aerobic Bio-Reactor (FAB) as the name indicates consists of floating media of cylindrical shapes and different sizes. As compared to conventional technologies FAB reactors are compact, energy efficient and user friendly. Considering all these aspects which is discussed below, FAB Technology is considered as best suited for this project for 160 KLD Sewage Treatment Plant. Basic Principle of FAB: FAB is based on the principle that as microorganisms grow with the aid of FAB media, they form particles that clump together with the aid of aeration system, digesting most of the organic matter during the process. These particles (floc) are allowed to settle to the bottom of the tank, leaving a relatively clear liquid free of organic material and suspended solids. The FAB media provides a very large surface area ( m 2 per m 3 volume) which Increases the specific volumetric capacity of activated sludge tanks Controls biomass activity Reduces operating cost The clarified sewage enters into the FAB reactor, which contains the FAB media. The FAB media significantly increases the surface area for bacterial growth. Air is supplied through fine bubble diffusers. Bacteria oxidize the organic matter present in the sewage. Oxidized sewage overflows out of the FAB reactor, into the secondary settling tank. Advantages of using FAB Reactor: Significant reduction in space requirement due to high surface area & loading rate of FAB media. Reduced power and operating costs. No sludge recycle required hence no sludge recycle pumps. FAB Reactor is best suitable when designing a new waste water treatment plant, where operating cost and space are constraints.

(mg/l) : mg/l (g) BOD (mg/l) : mg/l (h) COD (mg/l) : mg/l TREATMENT PROCESS The treatment process is designeded for removal of suspended BOD and COD, followed by aerobic treatment and polishing treatment. The treatment will have three following prime stages M/s Comely Buildtech India Pvt. Ltd. 14

15 a. Primary Treatment Sewage initially enters screen chamber and oil and Grease trap. The sewage enters screen chamber; the flow is continuous and larger suspended solids >10 mm dia. are trapped between the screens which are to be removed manually for either land filling or incineration. This sewage then passes through the Oil & Grease Trap (OGT) where Oil & Grease are removed. The basic function of OGT is to prevent fat, oil, and solids from reaching the drain. Fats, oil and grease (FOG) float on the surface of water which skims out. OGT looks like baffled tank. This helps in reducing BOD, COD load by about 15%. This is practically maintenance free as it contains no mechanical moving part. The sewage is collected in the collection cum equalization tank. Water from equalization tank then enters aeration tank. Oxygen is diffused into this tank to increase oxygen level of sewage as well as keep it agitated form to prevent sludge formation in this tank and avoid anoxic conditions (Air from blowers keep the sewage in agitated form). The sewage is pumped to FAB reactor through auto control method at a constant rate for further treatment. Oil and grease trap and equalization tank is cover from top to avoid smell. b. Secondary Treatment The equalized sewage enters the FAB bio-reactor for aerobic digestion of the organic matter. Air is supplied to both the tanks through air blower and coarse bubble membrane diffusers. The FAB media are of circular/cylindrical shape free-floating media with surface area of m 2 / m 3 volume. It provides a large surface area for microorganisms to attach themselves. These micro-organisms feed on the organic matter present in the sewage. Nutrient dosing is done in cases when situation arises for proper maintenance of CNP Ratio using DAP and Urea. In situations when the plant is reopened after shut down, one needs to provide hauling of Cow dung and/or DAP, Urea during recommissioning period to provide nutrients for the microbes. The treated sewage then moves to the clarifier. This tank incorporates specially designed Tube Settler Media for setting finer particles; the tube settling media are specially designed which provides a large settling surface area within the specified volume thus giving high flow rates. They have a chevron shaped self-supporting structure in a tubular form with six sides. Tube Settler Media have no moving parts as a result of which there is M/s Comely Buildtech India Pvt. Ltd. 15

16 no energy loss. The distribution and entry velocity are minimum resulting in maximum efficiency and better effluent quality. Sludge pumps are provided to remove sludge from the settling tanks and transfer it to a sludge tank which in turn transfers it to the sludge de-watering device like a filter press. Sludge cake can be collected manually in plastic bags and can be used as manure for plantation uses after complete drying or sold as manure. The concentrated wastewater from the filter press is returned to the EQ tank for further treatment with the objective of achieving zero wastewater discharge. c. Tertiary treatment Disinfection of treated water is carried out using chlorination and is stored in filter feed tank and passed through MGF and ACF for removal of residual BOD, color, odor, suspended solid & hardness. Treated water after the tertiary treatment has been used for horticulture/irrigation & cooling tower. Sludge withdrawn from the clarifier tank is transferred to sludge holding tank and sludge drying bed where sludge has been thickened and digested and finally either disposed-off eco-friendly manner or used as manure. CHARACTERISTICS OF TREATED WATER (a) ph : 6.5 to 7.5 (b) Oil & Grease : <10 mg/l (c) B.O.D. : <10 mg/l (d) C.O.D. : <30 mg/l (e) Total Suspended Solids : <10 mg/l 1.9 STORM WATER MANAGEMENT Storm water harvesting system will be provided within the project site as per CPCB guideline on Rainwater Harvesting & Artificial Ground water Recharge. Storm water from roof-top will be collected via storm water drainage network and will led into recharge pits proposed to be provided within the site. Storm water drainage will be designed in line of existing drainage pattern and considering the natural flow direction of water. First flushing system will be provided to prevent water from first rain to enter the ground as it is believed to contain several impurities. Rain water harvesting system is designed considering maximum peak hourly rainfall (50 mm/hr). Thus pits are designed to accommodate the maximum possible rainfall taking in M/s Comely Buildtech India Pvt. Ltd. 16

17 consideration peak hourly rain-fall for that area. Retention time for water in pit is considered to be 15 minutes. De-silting chamber is provided with each RWH pit.

Evergreen, native species will preferably be planted at the project site. Native species are adapted to natural conditions and also requires less aftercare and maintenance. Trees with large & round canopy will be planted. Plantation will act as noise buffer and will 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. Phytoremediation is one of the most successful available technologies of restoring the degraded environment. For this project area of m 2 (50 % of the open area) is proposed to be put under green cover. Green cover will comprise of: A peripheral green belt Planters along the roads M/s Comely Buildtech India Pvt. Ltd. 20

21 Lawns/parks 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 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 SO 2 and NO 2 should be preferred 9.
