“They have a regular pork farm system and use wood chips in the trucks while hauling the pigs. The truck wash system separates out the wood chips with a Key Dollar side hill separator. The water from this goes to a Key Dollar micro-screen separator with a 325 mesh screen. The water then goes to settling tanks and then to the fields for watering. The wood pulp floats off and the solids go to the soil.”– Testimony for the 325 Mesh Stainless Steel Screen
