Defense Distribution Depot Red River
Existing paint particulate filters were loading up with paint and sagging, resulting in paint by-passing the filter. Research was conducted to locate a rigid filter to correct they by-pass problem. A new type of styrofoam filter system was purchased from Air Filtration Company, Inc. of Iowa which not only solved the by-pass problem, but also eliminated a solid waste stream. Used filters are dissolved in spent paint solvents which are recycled on-site.
Additional savings were gained when it was noticed that paint filters were loaded unevenly with paint. Maintenance procedure were altered to only replace loaded filters instead of the entire filter bank. After publicizing the success in the newsletter of the facility the entire Army Depot adopted the filters reducing waste an additional 50%
This process eliminated 48,000 pounds of hazardous waste a year. By eliminating paint by-pass these filters also decreased air emissions.
