Better filtration, less money
Keller set out to develop a sustainable process which incorporates a dry separation system for wet paint overspray. The result is a system they say reduces overall costs up to 85% by using a regenerative filtration system that eliminates disposable filter media or water based wet scrubber costs, as well as minimizing related energy consumption.

Finisher's Think Tank: Rinsing: An Important Part of the Cycle
The following points may apply to specific metal finishing operations, such as: plating, painting and powder coating, anodizing, colorizing, oxidizing and other specialties.
Read MorePhosphates in Wastewater
I am charged with finding the sources of phosphorus in our plant. Our main process effluents are from mass finishing and washing machines. I have not found significant phosphorus in these fluids, and yet, we are close to the limit. What am I missing?
Read MoreBetter Transfer Efficiency
To protect and preserve the brass plating, we coat these parts with a clear lacquer using a conventional air spray gun. Needless to say, we get poor coverage on the parts with a lot of overspray. Consequently we use a lot of lacquer. Because of the rising prices of coating materials, I’ve been asked by management to reduce our manufacturing costs.
Read MoreDecontamination of Metal Finishing Area
We have a finishing room at one of our plants, and we have outsourced the plating. We also did pickling and bright dip in the room, and we now want to decontaminate it so that we can sell the equipment, or at least dispose of it properly. Our main concerns are cyanide, silver and nickel.
Read MoreDo We Have a Large Load?
We have a captive metal finishing operation and are looking at a process that will have a waste stream with 10,000 ppm Chemical Oxygen Demand at an average flow rate of 4 gal/min that will be discharging into our city’s wastewater treatment facility, which has a capacity of 2.5 million gal/day. Is this a large load for such a facility?
