Purification processes for the treatment of waste water
Cohin Environnement has devoted great efforts to the waste water treatment purifying processes and to all the more common processes of water treatment and the associated by-products such as:
  • Pre-treatment
  • Biological Processes
  • Physical-Chemical Treatment
  • Sludge treatment
  • Liquid/Solid Separation
  • Media filtration
  • Tertiary Treatment

PRE-TREATMENT

Our Processes


This first stage of treatment eliminates the coarsest materials (oils, fats, sands, solids)

We can supply you with static or mechanical solutions:

 

  • Decanter
  • Oil remover
  • Desander
  • Separators
  • Sieves

Things you need to know!

Cohin Environnement defines hand in hand with you the technical solutions needed for the pre-treatment of your raw water.

 

BIOTREATMENT

Our Processes


We have solutions adapted to the biological treatment of your waste water thanks to our know-how in the implementation of various processes.

Cohin Environnement can supply solutions for free or fixed cultures:

 

  • Activated sludge
  • SBR
  • Aerated ponds
  • Reed-planted beds

Things you need to know!


We can guide you choosing and implementing the process.

 

PHYSICAL-CHEMICAL TREATMENT

Our Processes

Depending on your type of influent, we can set up treatment like:
  • Flocculation
  • Coagulation
  • Flotation
  • Précipitation
  • Évaporation
  • Neutralization

Things you need to know!

For particularly polluted waters COHIN ENVIRONNEMENT can determine the physical and chemical treatments to be set up to achieve your discharge standards.
