Before US Centrifuge Systems

A private manufacturer of metal roasting pans sprays 20 gallons of paint per day onto the pans. Half of the paint over spray was building up short of the wash water used to remove excess paint on an extended pan located directly in front and below the chain conveyor line. The operator was flushing off this mass of live paint with a hose directly into the booth sump at the end of the shift. Since it was impossible for the polymer to de-tackify these globs of paint, they plugged the upper water spray manifold. The centrifuge being used at this time was drastically undersized for this operation and filled up within two hours. Large amounts of foam being generated from the high paint solids content in the booth water required de-foamer.

Beyond the Centrifuge

US Centrifuge Systems expanded its research and development in 1999 with a successful waste-to-energy system that can now convert up 8 tons of waste within one hour of operation into renewable energy. Sister company Organic Power Solutions was established, and now, high-value co-products are created and used in the production of in-house renewable energy or sold to third-party utility companies.

The water wash paint booth had to be entirely cleaned out every four weeks, resulting in four operators working costly non-production 10-hour days. Eighteen drums of live paint sludge were generated at a sludge disposal cost of $400 per drum.

Solutions

US Centrifuge Systems added a short water flood sheet to the front of the booth directly below the conveyor chain in order to catch all of the over spray as an atomized paint particle. A high efficiency PVC unit replaced the upper standard metal pipe manifold. The manufacturer's manual centrifuge was replaced with a US Centrifuge Systems automatic centrifuge, and the US Centrifuge Systems engineers set up automated chemical feed with inline draw down tube.

Results

All paint over spray enters booth water as an atomized spray paint particle. Live paint clumps are nonexistent now. This manufacturer experiences quick and thorough de-tackification of all paint solids from improved manifold and efficient removal of paint solids from the automatic centrifuge.

After installation of the US Centrifuge Systems Centrifuge, the only manual labor requirement is changing the sludge drum when filled. Sludge is relatively dry and compact with no solvent content and is landfill disposable at a much lower cost. The booth is cleaned out only once per year, yielding no drums of live paint sludge.
