The average volume of waste water in dairies is currently 1.3 l/kg milk. This results in considerable waste water disposal costs. GEA technology paves the way for major potential savings by minimizing the use of fresh water and reducing the volume of residual sludge.

Hygiene is the most important factor in milk processing and the production of dairy products. This necessarily results in the use of considerable volumes of water for cleaning purposes. In addition, considerable quantities of waste water with volatile milk constituents, fats and proteins occur when milk is being processed, particularly during evaporation and spray-drying.
GEA supplies ideal modules for this application in the form of special decanters which save money boost efficiency and are user-friendly. After aerobic or anaerobic biological treatment of dairy waste waters, the residual sludge is sent through a clarifying decanter which efficiently dewaters the sludge before the clean water is recycled back into the process.
