Zero Liquid Discharge

A ZLD System is a modern water treatment system that cleans wastewater, recovers reusable water, and eliminates liquid waste. It ensures no harmful liquid is released into the environment.

How It Works:

  1. Cleaning Water: Wastewater is first cleaned to remove dirt and large particles.
  2. Concentrating Waste: The system removes extra water and makes the waste more solid.
  3. Separating Solids: Solid waste (like salts) is separated from the water.
  4. Reusing Water: Clean water is purified and reused in the industry.
  5. Safe Disposal: Solid waste is safely disposed of or reused.

Uses:

  • Industries: Cleans wastewater from factories like power plants, textiles, or food.
  • Chemicals: Recovers valuable chemicals from waste.
  • Mining: Cleans slurry and gets usable water from mining waste.

 

Benefits:

  • Eco-friendly: Helps protect the environment by avoiding liquid waste.
  • Saves Water: Reuses water and reduces the need for fresh water.
  • Cost-effective: Cuts down waste disposal costs and reuses resources.
  • Customizable: Can be adjusted to fit different industries and needs.
  • Reliable: Works smoothly with advanced technology.

Process Flow for Zero Liquid Discharge (ZLD) System

Wastewater Inlet → (Raw wastewater enters the system for treatment)

Pre-Treatment Unit → (Removes dirt, large particles, and suspended solids)

Concentration Stage → (Removes excess water, increasing waste concentration)

Solid-Liquid Separation → (Separates dissolved solids such as salts from water)

Water Purification Unit → (Treated water is purified for reuse in the industry)

Final Disposal System → (Solid waste is safely disposed of or reused)

Key Equipment Involved

Screening & Filtration Unit (Removes large particles and debris)

Chemical Treatment Unit (Enhances separation of impurities and dissolved solids)

Evaporator System (Concentrates wastewater by removing excess liquid)

Crystallizer (Extracts and separates solid salts)

Reverse Osmosis (RO) Unit (Purifies and recycles treated water
