Effluent Treatment Plant for Dairy Industry

Our Effluent Treatment Plant for dairy industry is specifically designed to treat wastewater generated from milk processing, cleaning, pasteurization, cheese/butter manufacturing, and CIP operations.

Our advanced systems efficiently remove fats, oils, grease (FOG), lactose, proteins, dissolved solids, and biodegradable organic matter, ensuring the treated water is safe for reuse or discharge. Each plant is customized based on wastewater characteristics, processing capacity, and regulatory requirements to ensure seamless treatment and compliance with CPCB/SPCB norms.

We use advanced technologies like:

• Membrane Bio Reactor (MBR)

• Moving Bed Biofilm Reactor (MBBR)

• Activated Sludge Process (ASP)

• Sequential Batch Reactor (SBR)

• Fluidized Media Bio Reactor (FMBR)

• Fluidized Aerated Bio Reactor (FAB)

• Submerged Aerobic Fixed Film Reactor (SAFFR)

Product Description

We provide high-performance ETP for dairy industry that treats wastewater from milk reception, fermentation, equipment washing, and product processing, ensuring compliance with pollution control standards.

Dairy effluent typically contains high BOD, COD, fats, oil & grease, lactose, proteins, suspended solids, and disinfectants. Our ETP plant design for dairy industry integrates anaerobic, aerobic, and hybrid biological treatment systems to ensure efficient removal of organic pollutants and achieve high-quality effluent output.

Anaerobic Treatment

Uses UASB reactors, digesters, and filters to break down high-strength organic load and generate biogas.

Aerobic Treatment

Uses diffused aeration, activated sludge, and biofilm processes to remove remaining organic matter and nutrients.

Hybrid Systems

Combines anaerobic and aerobic processes to efficiently manage fluctuating load and complex dairy wastewater composition.

For small or cluster-based dairy processing units, Common Effluent Treatment Plant (CETP) helps achieve treatment efficiency at lower operational cost and supports Zero Liquid Discharge (ZLD) goals.

Functionality

The effluent treatment plant for dairy industry follows multiple treatment stages to remove solids, organic matter, nutrients, and pathogens.

Preliminary Treatment:

Removes sand, grit, milk residues, and floating fats through screening and skimming.

Primary Treatment:

Uses chemical coagulation and flotation methods to remove suspended solids and FOG.

Secondary Treatment:

Biological treatment processes (aerobic/anaerobic) reduce COD, BOD, lactose, and dissolved organic matter.

Tertiary Treatment:

Advanced filtration, activated carbon filters, UV/ozone disinfection for polishing and reuse readiness.
