Zero Liquid Discharge systems - waste water recycling

The advantages of closed waste water systems:

  • - reduction of water and sewage costs
  • - reduction of water consumption
  • - the most environmentally friendly water management solution in the production sector

Closed circuits can be designed as:

  • Partially closed
    - recycles part of the waste water and thus reduces the production of discharged waste water 
  • Completely closed – Zero Liquid Discharge
    - all waste water is recycled back into the production process and no waste water is discharged

For the implementation of closed waste water systems, the following is used:

  • - adsorption on ion exchange resins
  • - separation of substances by membrane processes
  • - distillation using vacuum evaporators
