Sewage Treatment Plant

We provide Sewage Treatment Plants on turnkey basis. These Sewage Treatment Plants are set up for the treatment of the sewage waste that is produced by canteens, residential colonies etc. These involve collection, primary treatment, biological treatment and tertiary treatment to make it recyclable. We design the Biological Treatment Plants based on proven extended aeration technology, which is either based on suspended growth or attached growth as in the case of Fluidized Aerobic Bioreactor and Submerged Aerobic Fixed Film reactor. The selection of technology is based on capacity of plant, the operating staff at site and the investment capacity.

Sewage treatment Plant, or domestic wastewater treatment, is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. The task of designing and constructing facilities for treating wastewaters falls to environmental engineers. They employ a variety of engineered and natural systems to get the job done, using physical, chemical, biological, and sludge treatment methods. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds.

• The nature of the municipal and industrial wastes that are conveyed to them by sewers
• The amount of treatment required to preserve and/or improve the quality of the receiving bodies of water.

Discharges from treatment plants usually are disposed by dilution in rivers, lakes, or estuaries. They also may be used for certain types of irrigation (such as golf courses), transported to lagoons where they are evaporated, or discharged through submarine (underwater) outfalls into the ocean. However, outflows from treatment works must meet effluent standards set by the Environmental Protection Agency to avoid polluting the bodies of water that receive them.

• Aerobic STP :
  

  Oxygen/Air is continuously supplied to the Biological (Aeration) Reactor either by direct Surface Aeration system using Impellers propelled by Pumps or Submerged Diffused Aeration system using Air Root Blowers for Air supply through diffusers. Aerobic condition leads to complete oxidation of Organic Matter to Carbon Dioxide, Water, Nitrogen etc. thus eliminating Odor problem caused due to incomplete oxidation. Also Air supply aids in uniform and efficient mixing inside the tank.

• Anaerobic STP :
  

  Here sewage partially decomposed in closed Biological Reactor in absence of Air which leads to reduction of Organic Matter into Methane, Hydrogen Sulfide, Carbon Dioxide etc. The plant is widely used to treat wastewater sludge and organic waste because it provides volume and mass reduction of the input material to a large extent.
