What is STP and ETP?
Important systems like STPs (sewage treatment plants) and ETPs (effluent treatment plants) are made to handle various wastewater kinds for a range of uses.
Sewage Treatment Plant
Treating domestic sewage from homes, businesses, and institutions is the main objective of sewage treatment plants (STPs). Screening, primary settling, biological treatment (using trickling filters or activated sludge process), and disinfection are some of the steps involved in removing contaminants and pathogens from wastewater before it is released into natural water bodies or used again for non-potable uses. The intention is to stop the spread of waterborne illnesses and make sewage healthy for the environment.
Effluent Treatment Plant
ETP, on the other hand, deals with industrial effluents, taking care of the unique pollutants and complications related to industrial wastewater. Industries produce effluents that are contaminated with a variety of substances, including oils, chemicals, heavy metals, and organic compounds. To remove or reduce these pollutants, ensure environmental regulations are followed, and stop environmental degradation, ETPs use specialized treatments like chemical coagulation, sedimentation, biological treatments, and cutting-edge methods like membrane filtration or reverse osmosis.
