Alvest - Livestock Wastewater Treatment

The aim of this system, which was designed for a hog farm being constructed in a valley surrounded by farm fields, is to keep the hog operation from polluting the environment by eliminating all external discharge of liquid wastes. First, very fine mesh screens remove the solids, then a membrane bioreactor removes BOD and nitrogen. In the final step. RO treatment is carried out and the resulting water is reused. The RO concentrate is used as compost. In this way, the system successfully achieves zero emission.
