4.5 BRIEF WRITE UP ON THE STP PROCESS:The scheme proposed for the treatment of sewage is a compact and effective Sewage TreatmentPlant using the revolutionary “Moving Bed Bio Reactor (MBBR)” technology. The conceptunderlining the Moving Bed bioreactor is to provide continuously operating bio-film reactor,which is non-cloggable does not require backwashing and has a very low-pressure drop. This isachieved by growing the bio-film on smaller carrier elements that move along with the wastewater in the reactor. The air stream constantly keeps the bio media is in suspension and at thesame time provides the required oxygen to the biomass.The system uses specially designed bio-media, which provides a large surface area for biologicalgrowth. The bio-media is made of plastic material, which has a very long life. The media iscylindrical in shape and provides a large surface area in the given volume. The media providesabout 800 m2 effective area for growth of the bio film per m3 of volume.The proposed system will consist of the following major stages:1. Sewage Collection and Pumping System2. Manual Bar Screen and Grit Chamber3. Aeration Tank and Tube-deck Settlers4. Filtration System5. Disinfection System

1. Sewage Collection and Pumping System:Raw sewage will enter the raw sewage sump. Raw sewage transfer pumps will pump the sewageto the STP through the screen and grit removing stages. One Pump will be on duty and the otherstandby.2. Manual Bar Screen and Grit Chamber:A combination of coarse and fine screens will be provided for removal of floating debris from thesewage. The coarse screen will have spacing of 10 mm and will be periodically cleaned. The finescreen will have a spacing of 5 mm and will also be periodically cleaned. The outlet from theScreen Chamber is let into the sewage treatment system.3. Sewage Treatment System:The proposed Sewage Treatment System will have the following major components:a. MBBR Bio Reactor Unitsb. Tube Settler Unit.c. Aeration Systema. MBBR Bioreactors: The MBBR Aeration tanks are located next to each other. Each of thetanks will be provided with aeration pipelines at the bottom, which will be in stainless steel andare manifold to cover half the periphery of the tank. Aeration tank is filled with a specific


18 | P a g e

quantity of the bio-media, which is made of plastic material with a specific gravity just below thatof water, to enable it to remain in suspension.The inlet of the aeration tank is on the top with the sewage falling freely into the MBBR tank. Theoutlet is located on the opposite side, which has a perforated Screen mounted on it, whichprevents the bio-media from flowing out of the MBBR Tank. Both compartments are connectedto each other by a fabricated channel, which has perforated sheets on each side. The outlet of thesecond MBBR is connected to the Tube Settler Unit.b. Tube Settler Unit: Sewage from aeration tank along with biological stabilized solids will flowby gravity to the Compact Tube Settler Unit. The separation of solid from sewage is achieved bylaminar flow developed between the tubes. Due to this, heavier solids slide down along theinside of the tubes, whereas the clear water rises up and flows out.The sludge settling at the bottom of the tanks will be transferred from time to time to the sludge-holding tank. The clear water from the settling tank will overflow into the Filter Feed Tank.c. Aeration System: The Aeration System consists of 2 Nos. Air Blowers. One Blower will be onduty while the other will be on standby. The Blowers will be used for aeration inside the MBBR.4. Filtration System:This consists of a Pressure Multimedia Filter that removes any remaining suspended solids intreated water so as to ensure its total conformance with the discharge standards set by theregulatory authorities. The Filter is to be backwashed at pre-set intervals with water from theTreated Water tank.Disinfection System:The Disinfection System, which comprises of a dosing system, ensures complete removal of anyremaining harmful organisms in the water. The water flowing into the Polishing Filter Feed Tankis dosed with an oxidant above and then allowed to remain in the tank for a predeterminedtime so that there is enough contact time for the oxidant to totally disinfect the water.

SludgeThe excess sludge is pumped to the sludge tank from where de-sludging is to be done once every3 – 6 months (depending on load factors) by pumping out to tankers and disposal engagingcorporation private agencies.

5.0 RAIN WATER HARVESTINGThe storm water disposal system for the premises shall be self-sufficient to avoid anycollection/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 ofprecipitation, characteristics of the tributary area and the time required for such flow to reach thedrains. The drains shall be located near the carriage way along either side of the roads. Taking theadvantage of road camber, the rainfall run off from roads shall flow towards the drains. Stormwater from different areas be connected to adjacent drain by a pipe through catch basins.Separate and independent rain water drainage system shall be provided for collecting rain waterfrom terrace, paved area, lawns and roads. Independent rain water down takes of appropriatesize and number shall be provided in close coordination with Architect. Perforated pipe drainagesystem shall be provided for open-to-sky courtyard/lawn. The storm water runoff from thebasement ramp shall be separately collected and connected to sump at basement. Drain channelshall be provided in the basement level car parking and plant room areas within the floor fillabove the raft. Drain channels shall be provided with adequate slope to affect self cleaningvelocity and shall terminate in sumps. For each sump, 1 no. submersible pumps (1 working) and astand by trolley mounted sump pump (for emergency purpose) shall be provided for disposal ofcollected run-off. Pumps shall be installed in identified sumps and shall be operated by Hi-Lo levelswitches with automatic changeover between both pumps.The storm water disposal system for the premises shall be self-sufficient to avoid anycollection/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 ofprecipitation, characteristics of the tributary area and the time required for such flow to reach thedrains. The drains shall be located near the carriage way along either side of the roads. Taking theadvantage of road chamber, the rainfall run off from roads shall flow towards the drains. Stormwater from different areas be connected to adjacent drain by a pipe through catch basins.The major objective of rain water harvesting is to collect available run–off from roof duringrainfall in monsoon period without any health hazard, if any. The rainfall during monsoon infirst 7 to 10 minutes duration having dust palliatives and acid rain must be drained out to thedrainage network.The roof area is 4758 Sq.m. out of total land area of about 9267 Sq.m, the average annualrainfall from past ten years’ rainfall record is 1576 mm. About 80% of rainfall occurs duringmonsoon in four months considering a loss of 20% due to evaporation, percolation, and evapo-transpiration etc., the composite run off co-efficient may be taken as 0.80. The run-off availableis therefore, 4758.59 x 1.576 x 0.8 (cum) = 5999.63 cum. in 4 months. Therefore, the average dailycollection is 5999.63 / 120 = 50 cu m.

U.G.R., having capacities of 300 cum** should be sufficient to store 6-day collection. This will beprovided with arrangement of draining out the over flow water into storm water drain.** According build bye law, Storage requirements @ 6 Cum / 100 sq. m Roof area. Total Roof Area= 4758.59 Sq.m, Rain water Storage Tank = (4758.59/100) x 6 Cu = 285.51 Cum5.1 AREA CALCULATIONBased on the area statement received from the Architectural Layout, the gross area receiving therainfall for the entire Complex is as follows:Roof Areas 4758.59 m2Green Area 1863.39 m2Roads & Pathways & other services 2645.3 m2Total area 9267.3 m2As per data made available by the Indian Meteorological Department (IMD), the maximum rainfallintensity can exceed more than 80 mm/hr but it occurs once in a few years. The average rainfall intensityis 40 (Avg.) mm which generally occurs in one hour.5.2 RAINFALL & TEMPERATURE DATA OF PURI AS PER INDIA METEOROLOGICAL DEPARTMENT

5.3 RUN OFF (RAIN WATER) CALCULATIONThe runoff is being assessed as per following formula:Runoff = Catchment’s Area * Runoff coefficient * RainfallThe run off coefficient plays an important role in assessing the run off availability and depends on thecatchment characteristics. General values as given in The Gazette of India dated July 28, 2001 are asfollows:S. No. Type of Catchment Runoff Coefficient1. Roof Top 0.802. Green Area 0.203. Roads & Pathways 0.50However, for the purpose of calculations, the higher value of runoff coefficient is being consideredin view of unpredictable nature of rainfall for arriving at total storage volumes.
