Municipal wwt plant Switzerland

Activated sludge process. Effected by industrial waste water from paper and textile industry

PE 90.000

Operational start 2014

Motivation: Bulking sludge, requirement of more capacity and improvement of effluent quality

Results: Settling rate of 4 - 5 m/h, 50 % more capacity, reduction of COD, total-N and TSS in the effluent

Municipal wwt plant Germany

Activated sludge process. Effected by industrial waste water (Chemical industry)

PE 32.000

Operational start 2015

Motivation: Bulking sludge (ISV approx. 180 ml/g), requirement of more capacity

Results: Settling rate of 5 m/h, ISV < 70 ml/g; more capacity (updated administration permission: 40.000 PE)

Municipal wwt plant Germany

Activated sludge process

PE 45.000

Operational start 2016/2017

Motivation: Improvement of sludge settleability, effluent quality, process cost savings

Results: No bulking sludge, settling rate of 4 - 5 m/h, 50 % more capacity, reduction of COD, total-N and TSS

Municipal wwt plant Germany
