Introduction: What is an Effluent Treatment Plant?

An Effluent Treatment Plant (ETP) is a crucial facility designed to treat industrial wastewater before it is released into the environment or reused. Industrial processes generate wastewater that contains harmful pollutants, heavy metals, oils, grease, organic and inorganic contaminants that must be removed to prevent environmental damage and comply with government regulations.

With industries growing rapidly in urban hubs like Bangalore, Delhi, Mumbai, and across India, managing industrial effluents is now more important than ever. This blog will walk you through the essentials of an ETP—its importance, working mechanism, suitable capacity for your industry, customization, pricing, and how to stay compliant with CPCB norms. If you're seeking an ETP for industries, especially from a trusted wastewater treatment company in Bangalore or need effluent treatment solutions in Delhi, this comprehensive guide is for you.

Why Your Industry Needs an ETP

Whether you are in manufacturing, pharmaceuticals, food processing, chemicals, textiles, or dairy, your operations are likely producing harmful effluents. Failing to treat these effluents not only leads to severe environmental consequences but also results in penalties, shutdowns, and reputation loss.

Key Reasons to Install an ETP:

• Meet legal norms by Central Pollution Control Board (CPCB)

• Avoid heavy penalties and legal liabilities

• Reduce fresh water consumption by recycling treated water

• Contribute to your ESG (Environmental, Social, Governance) goals

• Enhance your brand image as an eco-conscious business
  
  

Understanding the ETP Process: How It Works

An Effluent Treatment Plant typically consists of a multi-stage purification process that includes the following stages:

1. Preliminary Treatment

• Screening of large solids, plastic, paper, etc.

• Oil and grease trap

2. Primary Treatment

• Sedimentation tanks to allow solids to settle

• Chemical coagulation and flocculation to remove suspended particles

3. Secondary (Biological) Treatment

• Biological processes using bacteria to break down organic matter

• Aeration tanks, activated sludge process, or Moving Bed Biofilm Reactors (MBBR)
  
  

4. Tertiary Treatment

• Filtration, UV disinfection, reverse osmosis, or advanced oxidation

• Ensures treated water meets standards for safe discharge or reuse
  
  

What Capacity ETP Does Your Industry Need?

The right capacity for your ETP depends on the volume of wastewater your plant generates daily. This is generally calculated as KLD (Kilo Litres per Day).

Varuna offers fully customizable ETPs for all industry scales—from micro units to large-scale manufacturing hubs.

CPCB Compliance: What You Need to Know

The Central Pollution Control Board (CPCB) has established effluent discharge norms that vary based on industry type and discharge location (surface water, land irrigation, sewerage).

Key Parameters:

• BOD < 30 mg/L

• COD < 250 mg/L

• TSS < 100 mg/L

• Oil & Grease < 10 mg/L

• pH between 5.5–9.0
  
  

How Varuna Ensures Compliance:

• Advanced automation and sensor-driven ETP systems

• Real-time water quality monitoring with data logging

• CPCB audit and report assistance

• Remote diagnostics and support
  
  

Effluent Treatment Plant Cost Breakdown

The cost of installing an ETP varies depending on the capacity, type of industry, type of effluent, level of automation, and discharge standards.

General Cost Guidelines for Sewage Treatment Plants (STPs)

The cost of an STP can vary based on several factors, including location, system design, capacity, and specific requirements. Actual costs can differ based on site-specific conditions, technology choices, and other variables.
