Optimization of an industrial wastewater treatment plant

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.
