Integrated water purification for water treatment

Wet exhaust and process gas cleaning systems require the use of techniques that separate the emissions absorbed by the liquid.

Whether it is a pre-cleaning, main cleaning or even an conductive final cleaning, these methods serve to reduce disposal costs or to avoid them altogether. As a result, water treatment systems are often an integral part of exhaust gas purification systems.

Areas of application

  • Wet electrofilter
  • Wet absorber
  • Cooling water circuits

 

Multi-stage water treatment

Due to the process, a multi-stage water treatment is sometimes necessary, whereby possibly additional sorption or absorption substances and chemical solutions are dosed.

  • Rotation filter
  • Flotation system
  • Backwash filter
  • Rotation filter
  • Water biology with membrane filter
  • Cross-flow systems
