The Moving Media Bio Reactor Technology is aadvanced 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. A typical sketch of bio reactor showing various components is given below. The MMBR / FAB Technology has following advantages over Conventional Systems like : 1 Low on civil works 2 Low space requirement 3 Low on operating cost due to higher Oxygen Transfer Efficiency. 4 Low on maintenance cost 5 Easy to operate with semi-skilled manpower 6 Higher efficiencies in pollutant removal 7 Effective removal of nitrates and phosphates 8 Quick retrieval of system after shutdown / power failure SPECIFICATIONS OF SEWAGE TREATMENT SCHEME Raw Sewage Characteristics Temperature Ambient ph 7.0 - 8.0 Total Suspended Solids 210 mg/l BOD 5 days at 20° C 170 mg/l COD 340 mg/l Oil & Grease 30 mg/l MPN 06 to 107 per 100 ML Treated Sewage Quality pH 6.5 - 8.5 Total Suspended Solids < 30 mg/l BOD < 20 mg/l COD < 100 mg/l Oil & Grease < 10 mg/l MPN < 1000 per 100 ML Moving Media Bio Reactor (MMBR) / FAB (Fluidised Aerated Bed) Process Designing, providing, constructing, hydraulic testing, commissioning and giving satisfactory trials of STP consisting of inlet chamber, screen chamber, grit separator, MMBR / FAB (based on technologies providing attached growth on plastic meddi kept suspended in the waste water due to low density of plastic and provided with compressed air for aeration with very high MLSS of greater than 15,000 mg/lit.) tank, secondary clari settler, sludge sump, sludge thickener, chlorine contact tank, chlorinator room/shed, sludge centrifuge, associated piping work with required valves, gates, drains, pathways, administration block cum laboratory, laboratory equipments, spare parts for 2 years of operation, etc. complete as turnkey job with all involved civil, electrical and mechanical works including HT Substation,Transformers,DG Sets ,Metering cubical,Instrumentation & control works etc.as per spacification inclusive of following items, units as per detailed specifications for civil, electrical and mechanical components with all duties and taxes, etc. complete.
