Usually, the screen is formed with wedge-shaped bars spaced from 0.02 inches to 0.06 inches apart. The most commonly used method has a stationary screen mounted on an incline with the slurry applied to the top edge of the screen (Figure 1). The liquid passes through the screen and is drained away.

Understanding Mechanical Solid-Liquid Manure Separation

The cost of mechanical liquid-solid separation systems can range from $10,000 $50,000. Separating out a portion of the solids from liquid manure would be beneficial for several reasons such as: (i) reducing the possibility of clogging pipes, and (ii) producing a valuable solid material that can be easily stored or field applied.
