| 16 | (I)Supply and installatio testing and commissioning of sewage treatment plant 40KLD(Pakage Type) : PROCESS DESCRIPTION – MOVING BED BIO REACTOR (MBBR)/ Fluidised Media Reactor (FMR) with Tertiary Treatment 40Cum/day Capacity The Moving Media Bio Reactor Technology is a advanced biological treatment process which has a combination of activated.sludge process and attached growth process. The bio reactor has lot of packing material called carrier media in suspension. and provides a large surface area for micro organisms to grow and degrade the organic matter in aerobic condition. Due to the use of carrier media, the higher concentration of bio mass is developed which helps to reduce the basin size, accept higher loading rates and take shock loads. The sewage after screening and grit removal flows by gravity into the BIO REACTOR wherein the attached growth, aerobic microbes will utilize pollutant in presence of oxygen thereby, further reducing BOD. The air required will be provided through coarse bubble air diffusers provided on the aeration grid at the bottom of reactor and using positive displacement, twin lobe, root type air blower for supply of oxygen The PP media is provided in the aeration tank to allow the aerobic microbes to grow and get attached. This media remains in fluid state in the aeration tank thereby keeping large number of microbial colonies moving in the tank and provide high concentration of bio mass available at all the time. The microbes get exposed to bio degradable organics in presence of oxygen and convert it into cell biomass, water molecule and carbon-dioxide. The microbial colony grows on plastic media. The excess bio mass gets sloughed and moves with treated water into subsequent unit. This sloughing action is a continuous process and the microbes keep on growing and sloughing. This is a very fast process and hence system becomes self sustaining. The dead bio mass generated will be separated in the CLARISETTLER TANK wherein tube media is provided for providing additional surface area for settlement of bio mass and thereby reducing the space requirement. The solid-liquid separation is achieved in this tank and clear supernatant will flow by gravity. The treated wastewater will be disinfected with Chlorine and allowed to react in CHLORINE CONTACT TANK prior to suitable disposal. (II) Designing (hydraulically, structurally & aesthetically), providing, constructing, hydraulic testing, commissioning and giving satisfactory trials of STP consisting of Inlet chamber(RCC), Fine bar Screen chamber(manual) RCC with steel screen, Oil & Grease Remover(RCC), Grit separator, Equalization Tank( 2 Tanks of 50% Capacity each), Air Grid for Equalization Tanks, Feed Pumps(2 No), Moving Bed Bio Reactor(s) with plastic media (of appropriate density, size and quantity to keep very high MLSS > 15,000 mg/lit), Air Blowers for MBBR, Tube Settler assembly, Sludge Drying Bed of appropriate size, Chlorine Dozing System, Chlorine contact tank, Foundation for all E/M equipments, Associated piping work with required valves, gates, drains, pathways, Electrical control Panel with interconnecting cable, spare parts for 2 years of operation, etc. complete as turnkey job with all involved civil, electrical, digital and mechanical works as per detailed specifications for civil, electrical and mechanical components with all duties and taxes complete.
