Treatment of Dairy Waste Water

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.

High amount of waste water in dairies

Milk Splash

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.

Saving money and boosting efficiency with decanter centrifuges

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.
