HS-200′s Success VS. Heavy Metals

A metal plating company uses rust preventative in a cleaning bath, resulting in a wastewater that contains suspended solids, 10-20 PPM oil, heavy metals, and calcium and magnesium. The system runs at 36 gpm. The treatment system for the water cleanup is as follows: a sand filter, bag filters, and ion exchange resin tank with a mixed bed resin, and an RO system (removes salts, soaps).

Every day they spent $60 on bags, the resin had to be regenerated every week, and both the resin tanks and RO membranes had to be cleaned every week.  The sand in the sand filter was replaced withHS-200. The oil content of the water is now less than 1 PPM. They are saving $50 per day on bags.  Cleanup of the RO membranes and ion exchange tanks plus regeneration or resins is now done every two to three weeks.

They reduced the cleanup and regeneration costs by one half to one third. Considering that it costs up to $10/cubic foot of resin for regeneration, plus all the disruptions associated with it, the use of HS-200 for water cleanup is extremely beneficial.
