Milk processing also involves large amounts of water, which are mainly used for system and equipment cleaning. In addition, large amounts of wastewater accrue, typically with load peaks and changing pollutants, depending on the processes of each factory. Effluents are charged with cleaning agents, solids and organic substances such as fats.

DAS equipment has been successfully used by dairies, cheese and milk producing factories worldwide. DAS offers biological wastewater pre- and full treatment solutions from the entire range of available systems, for various business sizes, and each can be individually tailored to the requirements of each client. To economically optimize the operating system, it can be useful to balance uneven wastewater streams that might considerably fluctuate during the course of one day. DAS offers compensating reservoirs that can be integrated into the system.

Biological wastewater treatment with highly energy efficient DAS technology allows, moreover, the multiple use of recycled process water, which significantly reduces water consumption and operating costs. DAS solutions flexibly adapt to fluctuating effluent loads. The biofilm method offers excellent process stability while keeping sludge production low.
