Could be slight worsening to slight improvement depending on whether salts are concentrated or removed from the land applied 

waste stream

Not Applicable

A filtration or screening device, settling tank, settling basin, or settling channel used to separate a portion of solids from a liquid 

waste stream.

Using amendments and separation could create high organic residues that when land applied could increase soil organic matter in 

excess of the application of untreated manure

Some alternatives are used to treat the waste stream to the point water can be reused by livestock. Liquid/solid separation is almost 

always the first step

Separation could favorably alter the waste stream to better provide the needs of growing feed and forage, but this would be minor

Not Applicable

Solid/liquid separation allows for better management of solid and liquid manure streams. Improperly managed solid manure may 

result in particulate emissions, however.

Solid/liquid separation can help to reduce emissions of VOCs via better management of aerobic solid systems and anaerobic liquid 

systems.

Separation may have an impact on the release of a number of manure constituents

Liquid/solids separators are very successful in facilitating the reduction of odor emissions from manure, particularly when solids are 

allowed to remain in an aerobic environment
