Holistic concept for water and recyclables recovery for the food industry in breweries – Part 1

In the food and beverage industry, hygiene and psychological aspects also play a role as consumers disapprove of “mixing” effluent water and food. In this article, strategies for water and recyclables recovery suitable for breweries are proposed. In part 1, pollution arising in brewery effluent water is described and various strategies for water recovery are presented. Part 2 discusses end-of-pipe treatment of effluent water using a combination of biological and membrane processes. Together with possibilities of utilising spent grains, a possible holistic concept is presented.
