Aerobic biological treatments of industrial effluents

In France, there are an increasing number of liquid effluent treatment plants on industrial sites. In many cases, biological purification using bacteria to eliminate biodegradable pollution is at the heart of the treatment process. This method remains difficult to master for industrial effluents, as it is often dysregulated by the different pollutants present in the effluents and their considerable variability.

Quality requirements resulting from technological developments in industry mean that the manufacture of process water is becoming increasingly technical.

At the same time, waste treatment is becoming a priority to which companies are devoting more and more effort.

In all industrial sectors (chemicals, food, paper, oil and petrochemicals, textiles, metallurgy, surface treatment), the water treatment specialist has to make its experience and know-how available to manufacturers (see
