Biological Treatments

To treat industrial water, the use of bacteria is common. The bacteria eliminates organic elements (sugars, proteins, fats…). The bacteria then degrades organic pollution in an aerated environment (aerobic tanks) or a simply agitated environment (anaerobic tanks). It is common to smooth the pollution with buffer tanks to avoid sudden load variations. However, if the production of sludge is important, dewatering can be considered as an option.

Physical and Chemical Treatments

Using physical and chemical techniques captures many organic or mineral compounds: metals, greases, suspended materials, emulsions…

 The treatment usually happens in three steps:

  1. Chemical – to coagulate / flocculate / precipitate pollution
  2. Physical – to separate the aggregates that form (clarification, flocculation primarily)
  3. Dewatering the formed sludge to discharge or reclaim

Reverse Osmosis

Ovive partners with many membrane providers which allows us to choose THE right membrane. That’s how we offer all maintenance parts for DT type modules. After all suspended materials are eliminated, the pretreated effluent goes through reverse osmosis.


To meet needs that arise every once in a while, Ovive offers mobile containerized reverse osmosis plants.

The layer collecting the permeate is ‘trapped’ between two membrane layers.

Reverse osmosis technology uses semi-permeable membranes that let water pass, but block and discharge ions and molecules. The effluent is then separated into a stream of pure water (the permeate) and a concentrated discharge (the concentrate).

After studying your ionic balance, Ovive can predict the conversion rate of a reverse osmosis facility.

Fine Screening

This process can be a treatment in itself or a step in a succession of processes.Our operating experience has led us to select systems that are versatile and easy to maintain.
