Reclamation and Reuse – Introduction

Reclamation and reuse ka matlab hai used or wastewater ko treat karke dobara industrial processes mein use karna. Chemical industries mein yeh practice water conservation aur environmental protection ke liye bohot zaroori hai. It helps reduce fresh water demand and wastewater discharge, especially in areas facing water scarcity.

Treatment Process for Reuse

  • Pre-treatment: Screens or filters remove large solids, oil, grease, and debris.
  • Primary Treatment: Sedimentation tanks settle suspended particles.
  • Secondary Treatment: Biological treatment (like activated sludge or MBBR) removes organic matter and nutrients (BOD/COD).
  • Tertiary Treatment: Advanced filtration, reverse osmosis (RO), or UV disinfection for removing fine particles, salts, and pathogens.
  • Polishing (Optional): Additional processes like activated carbon filters to remove odor, color, or trace organics.
  • Storage and Reuse: Treated water is stored in tanks and reused for cooling, cleaning, boiler feed, or irrigation.

Zero Liquid Discharge (ZLD) – Process

  • Pre-Treatment: Removes solids, oil, and toxic components.
  • RO (Reverse Osmosis): Separates clean water from concentrated brine.
  • Evaporation: Remaining water is evaporated using evaporators.
  • Crystallization: Final brine is crystallized to recover salts.
  • Solid Waste Disposal: Only solid residue is disposed of; no liquid discharged.
