We have a customer who treats liquid waste stream with a chemical that causes heavy metals to coagulate and float to the surface. The floating scum is allowed to dry to a hard crust, the tanks are drained and crusty coagulant is shoveled out manually.

They were needing more capacity which would require building another reclamation system. If they could eliminate the wait time for the coagulant to dry out, throughput time would be increased. Using a model 6064 2″ stainless steel Line Vac, they vacuumed the floating scum as it appeared on the surface. When the wastewater tested good, the holding pond was released and recharged with the next batch of waste to be treated.

This method saved them 2 days of waiting for the floating scum to harden.  Within that time they were able to treat an additional batch essentially doubling their capacity.
