Note how the structure was wetted down to achieve maximum compaction. Earthen gravity separator with a solid biocover. The separator is currently being agitated and pumped to a mechanical separator I an effort to clean out the solids. Note how the structure was wetted down to achieve maximum compaction. Wastewater is pumped to the top of the screen, solids are separated out by a scarping system and dropped off of the end.
Liquids return to the waste storage pond.
The screen may be perforated with differing sizes to increase separation. This picture shows the texture and consistency of solids after being separated by a mechanical separator. An inclined screen on the mechanical separator. You can see the wiping blades. Wastewater is pumped to the top of the screen, solids are separated out by a scraping system and drop off the end.
