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
