Package Sewage Treatment Plants

There is a Worldwide recognition that decentralized wastewater treatment is a better and more efficient alternative to a centralized wastewater treatment system when considered from the angle of investment and energy consumption. There are many areas within cities, towns, and villages that are impossible to cover through centralized treatment systems which take care of proper treatment and disposal of sewage.

In line with our innovative approach, we now bring to you Packaged Sewage Treatment Plants that are compact and can be used in a decentralized manner anywhere for wastewater treatment, delivering the best solution we have implemented so far. The technology used by us is an advanced version of MBBR.

Sintex Packaged Sewage Treatment Plants are based on anaerobic and aerobic processes and are designed to have dual functions for the efficient treatment of domestic wastewater from toilets, bathrooms, kitchens, and washing areas.

Operation Principle

          Solid Separation Zone (Anaerobic Zone)

The first stage transforms the influent solids into settled solids while allowing scum to float on the surface. It is a primary sedimentation zone in which settled sludge is stabilized by anaerobic digestion. The treatment efficiency of the chamber is in the range of 30% BOD removal.

      Aeration Zone (Aerobic Zone)

The second stage is in the aerobic zone along with plastic media inside the tank which in turn increases the surface area and retains micro-organisms long enough to digest the organic substances. Clearwater overflows to the next treatment chamber. Air is provided through blowers and higher contact time with the Biofilm on the plastic media facilities for efficient digestion. BOD removal is around 60%.

      Final Sedimentation Zone

The final stage involves sedimentation where organic waste is settled in the sedimentation zone. The settled waste in the bottom is pumped back into the solid separation zone as a return sludge having active biomass (MLSS) to increase the efficiency of the system. The output from this zone is the effluent that meets the stipulated pollution control Standards.

      Optional

For more Stringent effluent parameters, we also offer a Tertiary Treatment Plant (TTP) addition to the system which does the job of filtration that further improves effluents.
