The sewage water generated from any residential colony, Hotels, corporate offices will be collected in the sewage collection cum pumping sump after flowing through the screen Chamber & oil & grease tank for remove floating matter like paper, plastic, oil & grease etc. The collection sump helps to have a consistent flow of sewage for the STP plant. Collection sump will be kept aerated by coarse air diffusers to avoid foul smell. The sewage is pumped to Inlet Chamber provided with Fine bar screen for removal of fine suspended solids from there it is passed on to Grit channel for removal of grit in the waste water thus increasing the efficiency of MBBR reactor. Overflow of Grit channel by gravity goes to MBBR reactor.
In MBBR reactor plastic media are provided for attachment of bacteria. This media having high void age ratio more than 98% & high surface area 400 m2/m3 which increase more contact time bacteria to organic matter i.e. BOD. The bacteria oxidize the organic matter to CO2& H2O by the aeration principle. Inside the reactor Fine bubble membrane diffusers will provide mixing and oxygen for bacteria. In MBBR reactor dissolved oxygen level will be maintained 2 mg/lt. Twin-Lobe Blowers are provided for aeration. The biological system has to be operated continuously 24 hours and there by constant feed of sewage water is required.
The secondary clarifier/tube settler, which designed on low overflow rate, is provided after the MBBR reactor to enable separation of solids. A steep slope is provided in the secondary settling tank to eliminate the need of scrapper mechanism. A part of the sludge is recirculated to the MBBR reactor in order to maintain MLSS levels and a part is drained to the sludge drying beds. Acclimatized Bacterial Culture will be added into the MBBR reactor to give the advantages as mentioned in the salient points of our offer.If you are not able to understand or handle the process contact the sewage treatment plant manufacturers and suppliers.
Excess sludge needs to be dewatered and dried for easy disposal. The sludge from the tube settler is collected in sludge drying beds. Dewatered sludge will get dried by the natural heat of the sunlight. The sludge will be used as manure.
The Clarifier water collected from the collection launder of the tube settler is then passed to the Chlorine contact tank. In this tank a shot of chlorine dosing is given for disinfection.
The sewage water will be further passed through tertiary treatment comprising of filtration with Dual Media Filter for removal of micro-suspensions, color and odor. The treated sewage water will discharge to irrigation.
We provide complete solutions for sewage treatment plant which includes biological, physical and chemical treatment which are based on latest technologies. Our plant design offer minimum waste generation, low cost operation, minimum footprint area and eliminate water to the Govt. Specified standards.
Sewage Treatment Plant (STP) Technologies:
Modular/Prefabricated Sewage Treatment Plant:
We are engage in designing supreme range of Modular/Prefabricated Sewage Treatment Plants. The modular construction (for noiseless & odourless working) allows the increase of the processing capacity by placing more plants in parallel. All the equipments and control instruments of the plant are placed inside anti-vandal cabinet. These can be installed in a single day, are easily transportable, customizable and flexible in working.
Starting from packaged plants, our range is small stp to Large Size Sewage Treatment Plant (STP) for Residential, Townships, Commercial, Industrial, Hotel, Hospitals, Education Institutions, IT Parks, Farmhouse, Villas etc.
Features:
We are one of the leading waste water management treatment plant manufacturer and supplier. We have hundred plus water treatment plant installation experience.
Service provided: STP-350 KLD STP of capacity 350 KLD at HNGL is designed & installed by us. The approach we employ ensures the best operation and maintenance of the system & hence forth the quality of water at output meets the standards & norms of CPCB.
Service provided: STP of capacity 200 KLD. At DPS, erection & commissioning of STP was done from our end. The inlet stream had a fouling smell and other inadequate parameters like high BOD & high TDS. As a result of our efficient treatment, quality of output stream met as per the guidelines of PCB.
Service provided: STP-50 m3/day We designed and installed STP of capacity 50 m3/day at Essar Steel India Ltd. with the up to date technology in order to get the better clarified sewage water. The system provided by us would have the least recurring maintenance costs.
