Pork Slurry Treatment

Pig slurry treatment system comprising a primary treatment system consisting of equalization, filtration and worm pressing and a DAF system. The purification process continues with a secondary biological treatment system that includes: An anoxic biological system and an extended aeration biological system.

The proportions of both tributaries are variable, which makes the operation and stability of the system complex.
