Effluent Treatment Plant in Pharmaceutical Industry

Effluent Treatment Plant in Pharmaceutical Industry

by

Introduction

The pharmaceutical industry is one of the most essential sectors worldwide, producing life-saving drugs, vaccines, and medical products. However, the production process generates a large amount of wastewater that contains active pharmaceutical ingredients (APIs), solvents, antibiotics, chemicals, and organic compounds. If discharged untreated, this wastewater can cause serious environmental and health hazards, including antimicrobial resistance, soil contamination, and water pollution.

This is why the Effluent Treatment Plant (ETP) for the pharmaceutical industry has become an essential requirement. An ETP ensures that wastewater is treated to remove hazardous substances and meet discharge standards prescribed by the Central Pollution Control Board (CPCB) and international norms.

3D Aqua Water Treatment Company, with over 20 years of expertise, is a leading manufacturer and supplier of customized ETP solutions ranging from 1 KLD to 50 MLD, serving pharmaceutical companies across India.

In this detailed guide, we will explore:

  • Characteristics of pharmaceutical effluent
  • Treatment processes involved in pharmaceutical ETP
  • Benefits of installing ETP in pharma industries
  • 3D Aqua’s role as the best ETP manufacturer and supplier in India

Why Effluent Treatment is Crucial in Pharmaceutical Industry?

Pharmaceutical wastewater is highly complex compared to other industrial effluents. It contains:

  • High levels of organic matter from fermentation and synthesis processes
  • Antibiotics and APIs that can lead to antibiotic resistance in microbes
  • Solvents and chemicals harmful to aquatic ecosystems
  • Heavy metals from catalysts used in drug manufacturing
  • Pathogens from biological waste

If untreated, pharmaceutical effluent can cause:

  • Toxic impact on aquatic life
  • Soil infertility due to chemical accumulation
  • Spread of antibiotic-resistant bacteria
  • Threats to human health through contaminated water sources
  • Legal consequences due to non-compliance with CPCB norms

Thus, a pharmaceutical effluent treatment plant is not just a regulatory requirement but also an ethical responsibility of the industry.

Characteristics of Pharmaceutical Wastewater

Pharmaceutical effluent varies depending on the manufacturing process but generally shows the following characteristics:

  • pH: 4.5 – 9.0
  • BOD (Biological Oxygen Demand): 700 – 3000 mg/L
  • COD (Chemical Oxygen Demand): 1500 – 6000 mg/L
  • TDS (Total Dissolved Solids): 2000 – 10,000 mg/L
  • Heavy metals: Chromium, lead, cadmium, mercury, etc.
  • Toxic compounds: Antibiotics, phenols, organic solvents

This makes advanced multi-stage treatment mandatory for pharmaceutical wastewater.

Treatment Process in Pharmaceutical Effluent Treatment Plant

A pharmaceutical ETP is designed with multiple stages to ensure removal of hazardous compounds.

1. Pre-Treatment

  • Screening for large solids
  • Equalization tanks to homogenize effluent
  • Oil & grease trap to remove hydrocarbons

2. Primary Treatment

  • Coagulation & Flocculation: Addition of chemicals (alum, PAC) to remove suspended solids
  • Neutralization: Adjusting pH for further treatment
  • Primary Clarification: Sedimentation of heavy particles

3. Secondary Treatment (Biological Process)

Pharma wastewater often contains biodegradable organics. Biological treatment helps in reducing BOD & COD.

  • Activated Sludge Process (ASP): Microbes degrade organic matter in aeration tanks
  • Moving Bed Biofilm Reactor (MBBR): Biofilm carriers increase microbial activity
  • Sequential Batch Reactor (SBR): Advanced aeration system with high efficiency
  • Anaerobic Reactors: For high COD load effluent, producing biogas as a by-product

4. Tertiary Treatment (Advanced Processes)

Since pharmaceutical effluent contains toxic and non-biodegradable substances, tertiary treatment is crucial:

  • Activated Carbon Filtration: Removes residual organics and colors
  • Membrane Filtration (UF/NF/RO): Removes dissolved solids and trace pharmaceuticals
  • Advanced Oxidation Processes (AOP): Ozone, UV, or Fenton’s reagent to degrade complex organic molecules
  • Disinfection: UV or chlorination to kill pathogens

5. Sludge Handling

  • Dewatering via filter press or centrifuge
  • Stabilization of sludge
  • Safe disposal as per hazardous waste rules

Advanced Technologies Used in Pharmaceutical ETP

Pharmaceutical wastewater often requires hybrid and advanced technologies:

  • MBR (Membrane Bioreactor): Combines biological treatment with membrane filtration for high-quality output.
  • ZLD (Zero Liquid Discharge): Evaporation and crystallization to ensure no discharge.
  • AOPs (Advanced Oxidation Processes): Effective against non-biodegradable pollutants.
  • Electrocoagulation: Removes suspended and dissolved pollutants using electrochemical reactions.

Benefits of ETP in Pharmaceutical Industry

  1. Environmental Protection – Prevents contamination of rivers, lakes, and groundwater.
  2. Regulatory Compliance – Meets CPCB and WHO discharge standards.
  3. Water Reuse – Treated water can be recycled for cooling, gardening, and utilities.
  4. Energy Recovery – Biogas from anaerobic digestion can be used in boilers.
  5. Corporate Responsibility – Enhances company reputation as eco-friendly.
  6. Cost Saving – Reduces freshwater dependency and lowers disposal costs.
