Experts in the water cycle in industrial environments,  John Cockerill Environment proposes effective and made to measure treatment technologies for process water, which encourages water recycling upstream of use as well as downstream, by purifying used industrial water.

Used in industrial installations for the correct functioning of a process or a product, process water has to be ‘purified’ in order to respond to the specific demands and requirements of each industrial concern.

To achieve this, John Cockerill proposes various techniques which may be put to work successively according to the type of industrial process desired. Water destined for the process can be prepared via two major channels: membrane filtration or ion exchanging resins. According to the quality of the water desired, a finishing treatment – ‘polishing’ – may be required on a bed of resin mix – mixed bed – or electro-de-ionization (EDI).

John Cockerill also proposes alternative sources such as water pumping from surface water or the subterranean water table. The choice of equipment will be dependent on the particular constraints of the project.

Classic pre-treatment techniques:

  • Screening
  • Decantation
  • Sieving
  • Membrane filtration
  • Filtration
  • Ion exchanging resins
  • Lime de-carbonation
  • Iron and manganese removal etc.

Applications :

  • Coolant water
  • Cleaning water
  • Vat water
  • Degreasing baths
  • Medicine components

John Cockerill Environment provides its clients with personalized and global assistance which responds to the economic and environmental challenges of industrialists: reduction of the environmental impact of your activities and improved energy performance of your installations!
