Effluent Treatment & Wastewater Treatment Plant
What is an ETP?
- ETP (Effluent Treatment Plant) is a process design for treating the industrial waste water for its reuse or safe disposal to the environment.
- Influent: Untreated industrial waste water.
- Effluent: Treated industrial waste water.
- Sludge: Solid part separated from waste water by ETP.
Need of ETP
- To clean industry effluent and recycle it for further use.
- To reduce the usage of fresh/potable water in Industries.
- To cut expenditure on water procurement.
- To meet the Standards for emission or discharge of environmental pollutants from various Industries set by the Government and avoid hefty penalties.
- To safeguard environment against pollution and contribute in sustainable development.
Design of ETP
The design and size of the ETP depends upon:
- Quantity and quality of the industries discharge effluent.
- Land availability.
- Monetary considerations for construction, operation & maintenance.
Area dimension depends on:
- 1. Quality of wastewater to be treated
- 2. Flow rate
- 3. Type of biological treatment to be used.
- In case of less available land, CETP (Common Effluent Treatment Plant) is preferred over ETP
