Industrial effluents


The average amount of wastewater produced in dairies is currently 1.3 liters per kilogram of milk. This results in significant wastewater disposal costs. GEA sludge Decanters pave the way for significant savings by minimizing the use of fresh water and reducing the volume of residual sludge.

High volume of waste water in the dairy industry

Hygiene is the most important factor in milk processing and the production of dairy products. This inevitably leads to the use of large amounts of water for cleaning purposes. In addition, milk processing, especially evaporation and spray drying, generates significant amounts of wastewater containing volatile milk components, fats and proteins.

Cost savings and efficiency improvements with GEA sludge Decanters

GEA sludge Decanters are ideal for the treatment of dairy wastewater. After aerobic or anaerobic biological treatment of dairy wastewater, the residual sludge is treated with a GEA sludge Decanter. The sludge is efficiently dewatered before the clean water is returned to the process. Transportation and disposal costs are minimized.
