Industrial Sewage Treatment Plant

What is an Industrial Sewage Treatment Plant?

An Industrial Sewage Treatment Plant is a facility designed to treat wastewater generated by industrial processes. Unlike domestic sewage, industrial effluents often contain a mix of organic and inorganic substances, heavy metals, oils, greases, chemicals, and toxic materials. The treatment process aims to:

  • Remove suspended solids
  • Reduce chemical oxygen demand (COD) and biological oxygen demand (BOD)
  • Eliminate hazardous substances
  • Facilitate water reuse or safe discharge into water bodies

Key Components of an Industrial STP

1. Screening Unit

  • Removes large particles, plastics, rags, and debris.
  • Prevents damage to pumps and equipment downstream.

2. Equalization Tank

  • Balances the flow and concentration of pollutants.
  • Ensures a uniform load to subsequent treatment stages.

3. Oil & Grease Trap

  • Separates oils, greases, and hydrocarbons from the wastewater.

4. Primary Clarifier

  • Settles suspended solids and sludge from the influent.

5. Biological Treatment (Aeration)

  • Uses microorganisms to break down organic matter.
  • Common methods: Activated Sludge Process (ASP), Moving Bed Biofilm Reactor (MBBR), and Sequential Batch Reactor (SBR).

6. Secondary Clarifier

  • Separates treated water from biological sludge.

7. Tertiary Treatment

  • Involves filtration, disinfection (UV/Chlorination), and polishing to achieve desired water quality.

8. Sludge Handling System

  • Includes sludge thickening, dewatering (using filter press or centrifuge), and safe disposal.

Types of Industrial STP Technologies

  • Conventional Activated Sludge Process (ASP): A widely used aerobic process involving aeration and sedimentation.

Industries that Require STPs

  • Textile & Dyeing Units
  • Chemical and Pharmaceutical Plants
  • Food and Beverage Processing
  • Paper and Pulp Industries
  • Automobile and Engineering Units
  • Petrochemical and Refineries

Importance of Industrial Sewage Treatment Plants

  • Regulatory Compliance: Industrial units must comply with pollution control board (PCB) norms.
  • Environmental Protection: Prevents contamination of rivers, lakes, and groundwater.
  • Sustainable Water Management: Treated water can be reused in processes, reducing freshwater consumption.
  • Operational Efficiency: Improves plant hygiene, safety, and reduces environmental liabilities.
  • Corporate Social Responsibility: Demonstrates environmental commitment to stakeholders.

Advantages of Using an Efficient STP

  • Reduced penalties and legal risks
  • Lower operational and maintenance costs with modern systems
  • High recovery rate of water
  • Space-efficient and automated operations
  • Improved image and trust among customers and authorities
