We are designing, supplying & installing Sewage Treatment Plantss as per size, budget, treatment, and requirements. We will provide prefabricated & civil structure based STP.
Electro coagulation (EC) is a water treatment process whereby an electric field is applied across plates to remove various contaminants from water. An Electro coagulation water treatment system represents a major advancement in wastewater treatment. A revolutionary electrical-based technology for treating complex waste streams economically and on-site.
Current is applied to the electrolytic cell plates, causing trace amounts of the plate material to be dissolved into the water. The action is similar to adding separation chemicals (polymers) to a chemical treatment system, but much less expensive. As previously defined, the electrical current and trace dissolved metals from the electrolytic cell plates because suspended matter came together, forming larger particles. Flotation during the reaction in the cell housing, oxygen bubbles are formed and attached to the coagulated matter, causing it to rise to the surface in the separation tank, where it is removed and transferred to the sludge holding tank. The air bubble separates from the separated contaminant, allowing it to sink to the bottom of the sludge holding tank, where it stays until it is properly disposed of by the customer.
A membrane bioreactor (MBR) is generally a term used to define wastewater treatment processes where a perm-selective membrane, e.g. microfiltration or ultra filtration, is integrated with a biological process, specifically a suspended growth bioreactor. MBRs differ from ‘polishing’ processes where the membrane is employed as a discrete tertiary treatment step with no return of the active biomass to the biological process. Almost all commercial MBR processes available today use the membrane as a filter, rejecting the solid materials that are part of the biological process, resulting in a clarified and disinfected product effluent.
Residence time (HRT) of sewage in a reactor is low due to the high concentration of bacteria & 100% removal of bacteria, there is no need to dose Hypochlorite. There is no need for secondary settling & sand, carbon filtration, which requires NO MANPOWER to operate. MBR: The Sewage Treatment Plants is programmed through PLC based controls so it runs automatically, which reduces the operating cost too.
The MBBR (Moving Bed Bio Reactor) system consists of an aeration tank with special plastic hexagonal- shaped, carriers that provide a surface where a bio-film can grow. The carriers are made of a material with a density close to the density of water. Generally, these are high-density polyethylene (HDPE), which has a density close to 0.95 g/cm3. The carriers will be mixed in the tank by the aeration system and thus will have good contact between the substrate in the influent/sewage wastewater and the biomass on the carriers.
The MBBR system is considered a bio-film process. Bio-film processes in general require less space than activated sludge systems because the biomass is more concentrated and the efficiency of the system is less dependent on the final sludge separation. MBBR systems don't need a recycling of the sludge, which is the case with activated sludge systems. Some other advantages compared to activated sludge systems are:
