The customer is a producer of dairy products including: milk, cheese, sour cream, butter and yogurt. In Sao Paulo City as in many large cities, the industries have to pay to discharge to the municipal wastewater system. This dairy was no exception. The immediate challenges they were facing were scaling issues and the lack of space to expand their treatment plant.


By choosing the Biowater CMFF® (MBBR) process combined with DAF separation the client was able to build the plant as compact as they had planned and still achieve the effluent quaility that they were aiming for. At start up the plant started having wave problems so the crew had to open up some 'breathing holes' which stopped the waves. In addition, foaming occurred which was predicted. Anti-foam products were used and handled the problem.

The customer’s existing process was equalization and DAF flotation, one tank and a DAF that was out of service Unfortunately there was no room for additional tankage. Biowater assessed the situation with their partner in Brazil, Acqua Engenharia. It was decided that the Biowater CMFF® (MBBR) Moving Bed Biofilm Reactor process was chosen because of it’s small footprint and low maintenance. The one tank was divided into two covered MBBR tanks. The existing DAF is now used as a secondary DAF.
