Lime will be dosed in for suppression of foaming tendencies. The clarified water will be filtered in a pressure sand filter after dosing of coagulant (alum) for removal of unsettled suspended impurities. This water will be passed through an activated carbon filter for removal of organics. The filtered water from ACF is then chlorinated & stored in the flushing tank. The attached growth fluidized aerobic bed reactor (FAB) process combines the biological processes of attached & suspended growth. It combines submerged fixed film with extended aeration for treatment of the waste water. The waste water after screening is collected in an equalization tank. The equalization tank is required for preventing surges in flow & facilitating equalization of characteristics over the M/s Aura Buildwell Pvt. Ltd. 54

10 entire quantity of effluent in a given time. A provision for pre-aeration is made in the equalization tank in order to ensure mixing & to prevent the sewage from going septic. The equalized sewage is then pumped into the FAB reactor for biological processing. The water enters the bottom of the reactor & flows up through the fixed film media which grossly enhances the hydraulic retention time & provides a large surface area for growth of biological micro organisms. The FAB reactor is aerated by fine pore sub surface diffusers which provide the oxygen for organic removal. The synthetic media floats on the water & the air agitation ensures good water to micro-organism contact. The FAB treatment is an attached growth type biological treatment process wherein the majority of biological activity takes place on the surface of the PVC media. Continuous aeration ensures aerobic activity on the surface of the media. Micro organisms attach themselves on the media & grow into dense films of a viscous jelly like nature. Waste water passes over this film with dissolved organics passing into the bio-film due to concentration gradients within the film. Suspended particles & colloid may get retained on this sticky surface where they are decomposed into soluble products. Oxygen from the aeration process in the waste water provides oxygen for the aerobic reactions at the bio-film surface. Waste products from the metabolic processes diffuse outward & get carried away by the waste water or air currents through the voids of the media. The aerated effluent passes into a tube deck settler for clarification. The theory of gravity tube settler system is that the carrier fluid maintains laminar flow in the settling media at specified maximum viscosity. These two parameters of a carrier fluid, flowing through a hydraulic configuration, will determine the velocity gradients of the flow, the height of boundary layer at the inclined surface and the residence time within the media. The carrier fluid must be viscous Newtonian, exhibiting a Reynolds number of less than 1000 and preferably, a number under 400. The laminar flow, through the inclined tubes, will produce velocity gradients sufficiently large to form an adequate boundary layer, where the velocity of M/s Aura Buildwell Pvt. Ltd. 55

11 fluid approaches zero. Boundary layers are necessary in functioning tube settlers, to allow suspended solids to separate from the viscous carrier fluid. Under gravitational forces, they will settle to the hydraulic surface of the tube and subsequently from the clarifier media. Since the tubes are inclined at 60 degrees, solids settled on the tubes are continually discharged down. This downward rolling action increases particle contact and hence further agglomeration, which increases the sludge settle ability. Studies show that these agglomerated sludge particles can have a settling rate in excess of ten times the settling rate of the individual flock particles in the influent. These heavy agglomerated masses quickly slide down the 60 degree inclined tube and settle at the bottom of the tank. At the bottom of the Tube deck, where the sludge leaves the Tube surface, the larger agglomerated captures smaller particles in the upcoming stream. This solid contact phenomenon greatly enhances the capture efficiency. Stages of Treatment: The treatment process consists of the following stages: Equalization Bio- Degradation Clarification & Settling Filtration Figure 2: Schematic Diagram of STP M/s Aura Buildwell Pvt. Ltd. 56

12 Sewer System The alignment and slope of the sewer line will follow the road network, drains or natural ground surface and will be connected to the trunk sewers. The discharge point will be a treatment plant, a pumping station, a water course or an intercepting sewer. Pumping stations will be provided at places where the natural slope of the terrain is insufficient to permit gravity flow or the cost of excavation is uneconomical to do the same. PROPOSED RAIN WATER HARVESTING SYSTEM The storm water disposal system for the premises will be self-sufficient to avoid any collection/stagnation and flooding of water. 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 will be located near the carriage way along either side of the roads. Taking the advantage of road camber, the rainfall run off from roads will flow towards the drains. Storm water from various plots will be connected to adjacent drain by a pipe through catch basins. Total 7 rainwater harvesting pits at selected locations, are provided 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 has been 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) For basement parking, the rainwater from ramps will be collected in the basement storm water storage tank. This water will be pumped out to the nearest external storm water drain. 4) The peak hourly rainfall of 35 mm/hr will be considered for designing the storm water drainage system. M/s Aura Buildwell Pvt. Ltd. 57

13 Rain water harvesting will be catered to and designed as per the guideline of CGWB. Peak hourly rainfall has been considered as 35 mm/hr. The recharge pit of 4 m diameter and 3 m depth will be constructed for recharging the water. Inside the recharge pit, a recharge bore will be constructed having adequate diameter and depth. The ground water level in the area is meters bgl. At the bottom of the recharge well, a filter media will be 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 will be 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 will 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 minutes of rainfall is flushed off. No sewage or wastewater will be admitted into the system. No wastewater from areas likely to have oil, grease, or other pollutants will be connected to the system.

22 Total green area measures m 2 i.e % of the open area which will be area under tree plantation along the roads. Evergreen tall and ornamental trees like Saraca asoca, Delonix regia have been proposed to be planted inside the premises. Table 10: Landscape area details S.No Particulars Area in sq.m 1 Landscape area required (@50% of open area) 2 Landscape area proposed (@52.22% of open area) 3 Number of trees required (@ tree/100 sq.m of open area) 4 Number of trees required 1202 (MoEFCC norms) (@ 1 tree/80 sq.m of plot area) 5 Number of trees proposed 1210 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. For this project area of m 2 is proposed to be put under green cover. Green cover will comprise of: A peripheral green belt Avenue plantation Lawns/parks & grass cretes M/s Aura Buildwell Pvt. Ltd. 67

23 Planters Vertical plantation Plantation Plan Healthy and established sapling having 1m height shall be selected for planting in greenbelt to avoid mortality. Pit measurements of 1 m x 1 m x 1 m for big trees and 0.6 m x 0.6 m x 0.6 m for small trees and shrubs are proposed to be dug up at desired point in triangular pattern. The pit should be filled with earth, sand, silt and manure in pre-determined proportions. Saplings planted in these pits will be watered liberally. Trees in peripheral green belt will be grown at the distance of 5 m and plants along the road will be grown at distance of 1-3 m as per requirement. Three tier peripheral plantations will be developed composed of front and rear row of medium and dwarf trees and middle row of tall trees so as to form a curtain of foliage around project site. Avenue plantation will composed of trees and shrubs in ratio of 1:3, whereas lawns and parks will contain trees, shrubs, herbs, grass and climbers. Close plantation also result in tall trees with deeper roots and ultimately yield more bio-mass per unit area and more efficient absorption of pollutants. Plantation of trees in staging arrangement in multiple rows across the direction of the wind is recommended for better trapping and absorption of the pollutants. 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 M/s Aura Buildwell Pvt. Ltd. 68

24 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. 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.
