Effluents from food and beverage factories contain degradable organic pollutants. Since industrial wastewater contains a diversity of impurities and therefore specific treatment technology called ETP is required. To reduce the usage of fresh water in industries..
Besides, why is ETP important?
ETP plays an important role in treating industrial wastewater as well as sewages generated from households. Packaged effluent treatment plants help both small- and medium-sized industries by disposing of the effluents generated at their facilities. Otherwise, it would be difficult for them to properly treat wastewater.
Secondly, what chemicals do ETP plants use? ETP Chemicals
- Urea/DAP.
- Anticipant liquid/powder.
- Sodium bi Carbonates for PH enhancement.
- Chlorine.
- Alum.
- Silica.
- Ferrous Sulphate etc.
Keeping this in consideration, how does ETP work?
Effluent: Treated industrial waste water. Sludge: Solid part separated from waste water by ETP. To clean industry effluent and recycle it for further use. To reduce the usage of fresh/potable water in Industries.
What is difference between STP and ETP?
National Standards for Waste Water Effluent from industry must meet the National Standards for waste water set by Government. So, Effluent Treatment plant ETP or Sewage Treatment Plant (STP) should design & operated in such a way that it treats the waste water to these standards.

Effluent Treatment Plants (ETP) 2. Sewage Treatment Plants (STP) 3. Common and Combined Effluent Treatment Plants (CETP). Wastewater treatment is a process, wherein the contaminants are removed from wastewater as well as household sewage, to produce waste stream or solid waste suitable for discharge or reuse.What is bar screen chamber?
A bar screen is a mechanical filter used to remove large objects, such as rags and plastics, from wastewater. It is part of the primary filtration flow and typically is the first, or preliminary, level of filtration, being installed at the influent to a wastewater treatment plant.What is STP in construction?
STP stands for sewage treatment plant. It plays a vital role in the process of removing the contaminants from sewage to produce liquid and solid suitable for discharge to the environment or for reuse. It is compulsory for larger apartments or larger community buildings to have a sewage treatment plant within the site.What is STP water?
Sewage Treatment Plant (STP) Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent).What is STP in industry?
