Evaluation of a Particulate Filtration System for an Alkaline Paint Stripper at Letterkenny Army Depot
Abstract
During metal pretreatment operations, U.S. Army depots use a variety of chemicals that become hazardous waste when no longer useful. Alkaline paint strippers are widely used to remove paint coatings from steel parts. At Letterkenny Army Depot (LEAD) in Chambersburg, Pennsylvania, these solutions are typically disposed of every six months, generating up to 2,200 gallons of liquid waste and three 55-gallon drums of sludge. By removing this sludge continuously, it is thought that the ongoing reaction between the sludge and active paint stripper can be prevented, thereby resulting in less depletion of the active bath ingredients and an ultimate reduction in hazardous waste. As part of its pollution abatement and environmental control mission, the U.S. Army Toxic and Hazardous Materials Agency (USATHAMA) is pursuing R and D projects to assist depots in meeting the Army goal of a 50 percent reduction in hazardous waste by the end of 1992 compared with 1985 baseline levels.
