Liquid-Solid Separators, also known as Rotary Drums, separate manure into two components – a thicker portion of concentrated manure solids and a less concentrated liquid portion. With a totally enclosed system for a safe and clean operation and interchangeable perforated, mesh, or combination screens, McLanahan Rotary Drums will remove up to 35% of the total solids based on the manure TS and screen selection. Dairy producers can use Rotary Drums to separate solids from the manure stream, thus improving water quality for use in sand separation, flush flume supply and land applications.
