Pipelines and sensors are blocked or sealed by grease deposits within a short time. In holding tanks, grease accelerates... Read more »

The longer untreated sewage or black water are stored in holding tanks, the more likely it is for anaerobic conditions to develop. Natural biological processes within the sewage consume oxygen and this consumption needs to be compensated. Anaerobic conditions can lead to the formation of... Read more »

The lower layers will then no longer be pumpable for discharge purposes and have to be manually removed from the tank, requiring a considerable amount of time and effort. To avoid having to execute this most... Read more »
