Effluent Treatment Plant for Dairy Industry

Effluent Treatment Plant for Dairy Industry

by

Introduction

The dairy industry is one of the fastest-growing sectors in India. From milk collection centers to large-scale dairy processing plants, massive volumes of water are consumed every day for processing, cleaning, cooling, and other activities. This water, after use, becomes wastewater containing milk solids, fats, proteins, detergents, and chemicals. If released untreated, dairy effluent can severely impact soil, groundwater, and nearby water bodies.

This is where an Effluent Treatment Plant (ETP) for dairy industry becomes crucial. An ETP ensures wastewater from dairy plants is treated to meet government norms before it is discharged or reused. It helps industries maintain compliance, protect the environment, and reduce water wastage through recycling.

In India, 3D Aqua Water Treatment Company stands as a trusted name in designing and supplying customized ETP solutions for the dairy industry, from 1 KLD to 50 MLD capacity. Whether you run a household-level small dairy unit, a cooperative milk society, or a large industrial-scale dairy plant, 3D Aqua offers reliable, cost-effective, and advanced effluent treatment plants tailored to your needs.

Why Effluent Treatment is Important for Dairy Industry?

Dairy effluent is highly biodegradable but has high BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand) levels. Untreated discharge can cause:

  • Water Pollution: High organic load depletes dissolved oxygen in water bodies, killing aquatic life.
  • Soil Degradation: Proteins, fats, and chemicals alter soil structure, reducing fertility.
  • Odor & Hygiene Issues: Decomposed milk residues cause foul smells, attracting pests.
  • Legal Penalties: CPCB and SPCB regulations mandate treatment before discharge.
  • Wasted Resources: Valuable water that could be recycled is lost if untreated.

Thus, installing an Effluent Treatment Plant (ETP) is not only an environmental necessity but also a legal and financial advantage for dairies.

Effluent Characteristics of Dairy Industry

A typical dairy wastewater stream includes:

  • Milk residues (casein, whey proteins, lactose)
  • Fats and oils
  • Detergents and sanitizers
  • Cleaning chemicals
  • High organic load (BOD & COD)
  • Suspended solids and sludge

Average Dairy Effluent Parameters

  • pH: 6.5 – 8.5
  • BOD: 1000 – 3000 mg/L
  • COD: 2000 – 5000 mg/L
  • TSS: 200 – 1000 mg/L
  • Oil & Grease: 50 – 200 mg/L

These parameters make treatment mandatory before discharge to municipal drains, rivers, or land.

Process of Effluent Treatment in Dairy Industry

3D Aqua designs ETPs using proven technologies for dairy wastewater treatment. A standard process involves:

1. Pre-treatment

  • Screening for large solids
  • Oil and grease removal
  • Equalization tank to balance flow and load

2. Primary Treatment

  • Coagulation and flocculation to settle solids
  • Clarification for suspended particle removal

3. Secondary Treatment

  • Aerobic Treatment (Activated Sludge / MBBR / SBR) for BOD & COD reduction
  • Anaerobic Digesters for high-strength effluent with biogas recovery

4. Tertiary Treatment

  • Filtration (sand, carbon, UF membranes)
  • Disinfection (UV, Ozone, Chlorination)
  • Reverse Osmosis (RO) for water recycling

5. Sludge Management

  • Sludge thickening and dewatering
  • Safe disposal or use as bio-fertilizer

This ensures effluent meets CPCB norms and can be reused for:

  • Gardening and landscaping
  • Boiler feed (after RO)
  • Cooling tower makeup
  • Floor and equipment washing

Benefits of ETP for Dairy Industry

15 kld etp plant
  • Environmental Protection – Prevents water and soil contamination.
  • Regulatory Compliance – Meets CPCB/SPCB discharge norms.
  • Cost Saving – Reduces fresh water demand through recycling.
  • Energy Recovery – Biogas from anaerobic digestion can be used in boilers.
  • Sustainability – Enhances dairy industry’s green credentials.
