What should you avoid when buying a STP or ETP plant?


Sewage Treatment Plant (STP) and Effluent Treatment Plant (ETP) are the mechanism of clearing the waste water before releasing it into the water bodies. The STP are used profoundly to treat the water of the domestic and sewage waste, whereas ETP’s are used for clearing the impurities and pollutants coming out of factories and industries. Well, before discussing about essentials which should be taken care off before buying the STP or ETP we need to know the exact use of STP and ETP.

What is STP?

The sewage Treatment plant is used for the purpose of removing impurities, pollutants and chemicals out of the waste water, the STP are implanted mostly for treating domestic waste water. Municipalities use to setup the STP plants for treating the domestic waste water, so that, they could release it to some fresh water body or may use it for further purposes. The treatment of water in STP goes in three steps.

  • First or primary step is to remove solid particles from the waste water, sedimentation is applied for removing solid particles of pollutants.
  • Secondary step is to break down the organic matters by using biological filters.
  • Third and last step is to clean the water further for removing the remaining impurities.

What is ETP?

The Effluent Treatment plants are primarily used in industrial plants for treating waste water coming out of industries, these plants use to treat chemical substances present in the water coming out of plants and then after treating such contaminated water they release it into the water bodies or use it for other purposes. The treatment of water in Effluent Treatment plants goes in four primary steps and these steps are.

  • First step is Physical Treatment, which is to remove solid particles and other impurities by Methods like sedimentation, coagulation.
  • Second step is Chemical processes such as pH adjustment or to remove the chemically active pollutants from the water.
  • Third step is the Biological Treatment which is used to treat the organic pollutants that can be present in the waste water.
  • Fourth and last step is to remove specific contaminants or adjust the treated water as per the regulation made by statutory provisions about the treated water.
