Coarse Seperating Zone
After passing through the inlet flow distribution
system, the wastewater flows into the coarse separationg
zone. This area allows large oil droplets and heavy
solids to separate. This zone is important for many
reasons: 1) to further equalize and quiet the flow,
enabling the entire Entry Area of the coalescer to receive
well distributed flow; 2) to reduce the oil and solids
loading entering the coalescer; and 3) to provide space
for future up-grades.
