Water recycling and reuse

Water is a major challenge for industry, as it is used as a raw material, solvent or carrier fluid to convey energy.

Interests and benefits

To face regulatory, economic and environmental challenges, an industrial strategy must incorporate the optimization of water consumption and reuse.

The motivating factors include:

  • environmental regulations
  • the company’s image – in terms of employee and public perceptions
  • reducing the risk of dependence on one source – avoiding consumption restrictions
  • preservation of water resources
  • long-term savings on the cost of water

Membrane processes: essential technologies for water recycling

Membrane Solutions

Within this context, water recycling, also known as REUSE, is becoming increasingly important in the industrial sector. The main processes used include:

These technologies, which are part of Elmatec’s core skill set, are best suited to your industrial water reuse requirements.

Bacteriological control

In addition to chemical control, Elmatec offers disinfection methods for bacteriological control:

  • Ozone
  • Ultraviolet

ULTIMATE GOAL: Zero Liquid Discharge

The ultimate water and effluent recycling strategy is ZLD (Zero Liquid Discharge).

The ZLD is a closed cycle with no discharge. It paves the way to economic benefits by recovering salts and other valuable chemical compounds.

This type of system is made up of the following components:

  • Pretreatment (physicochemical, pre-filtration)
  • Membrane processes (UF, NF, RO, ED)
  • Evaporator and crystalliser (thermal processes)

 As a specialist in membrane treatments and working hand-in-hand with partner experts in thermal processes, Elmatec offers a complete technological solution for manufacturers wishing to move towards Zero Liquid Discharge.
