Abstract
A process for separating clean water which has an impurities content of less than 100 ppm from waste materials such as farm manure is disclosed. In a first step, a plate separator splits the waste material stream into a first effluent fraction and a first solids fraction. The first solids fraction then undergoes two stages of pressing to increase the solids contents to about 30 to 40 percent which makes it suitable for granulation or pelletizing. The first effluent fraction is treated in successive stages with various chemical agents resulting in the removal of most of the solids and inorganic impurities from the effluent to achieve drinkable water purity.
