Zohal Engineering Solutions

An Effluent Treatment Plant (ETP) is an industrial wastewater treatment system designed to remove contaminants, heavy metals, toxic chemicals, and other pollutants from industrial effluents before they are discharged into the environment or reused. ETPs are essential for industries such as electroplating, chemical manufacturing, pharmaceuticals, textiles, and food processing to comply with environmental regulations.

✔ Customizable Design: Tailored solutions for different industrial wastewater types.
✔ Multi-Stage Treatment Process: Includes physical, chemical, and biological treatment.
✔ Heavy Metal & Toxin Removal: Removes hazardous substances like chromium, nickel, zinc, cyanide, and acids from electroplating waste.
✔ Sludge Management System: Ensures safe disposal of solid waste.
✔ Automated Control Systems: PLC-based monitoring for efficient operation.
✔ Compliance with Pollution Control Norms: Meets CPCB, EPA, and local environmental standards.

1. Pre-Treatment:

   • Screening & Grit Removal: Eliminates large particles and debris.
   • Equalization Tank: Balances fluctuations in wastewater flow and pH.

2. Primary Treatment:

   • Coagulation & Flocculation: Uses chemicals to aggregate suspended particles.
   • Sedimentation: Removes settled sludge and precipitated heavy metals.

3. Secondary Treatment:

   • Biological Treatment: Uses bacteria to break down organic pollutants.
   • Aeration & Activated Sludge Process: Enhances decomposition of organic matter.

4. Tertiary Treatment:

   • Filtration & Polishing: Removes fine particles and dissolved solids.
   • Reverse Osmosis (RO) & Activated Carbon Treatment: Ensures water is purified for reuse.
   • Disinfection (Chlorination/UV Treatment): Eliminates bacteria and pathogens.

5. Sludge Treatment & Disposal:

   • Dewatering & Drying: Reduces moisture content in sludge.
   • Safe Disposal: Complies with hazardous waste management protocols.

�� Electroplating & Metal Finishing: Removes heavy metals, acids, and cyanides.
