Description: Pre-treatment of animal waste by solid/liquid separation has many advantages. A new mechanical device was developed to separate swine waste into solid and liquid fractions using an endless belt made of filter material and continuously cleaned by air flow. The performance of the micro screening unit was evaluated over a period of 3 mo. The efficiency of this unit in terms of solids removal increased with the content of solids in the influent slurry. For swine waste with dry matter in the range of 3- 8%, the efficiency was between 47 and 59%. The dry matter in the screened solids varied between 14 and 18%, and presented reasonable stacking properties. It was found that as much as 39% of organic carbon32-35% of TKN and 17.8-20.9% of total P were removed from the influent slurry in the micro screening process.
