NWT has optimized the aeration and air supply scheme at the industrial production site of one of the largest pulp and synthetic fibre producers in Europe.

The overall plant has a design load of 60 tCOD/d and includes two-stage anaerobic treatment followed by two-stage aerobic treatment, which should be optimised to increase the efficiency of the plant.

Pilot tests were conducted in 2016/2017 and subsequently implemented.
