River Street Metal Finishing filters acid to reduce chemical use

River Street Metal Finishing, Inc., located in Braintree, Massachusetts, has been anodizing aluminum parts for the electronics, medical, military and defense, automotive and marine, firearms, and aerospace industries since 1991. By installing an acid filtration system on their three anodizing tanks, River Street Metal Finishing has been able to maintain a more consistent quality of its acid bath, reduce its use of sulfuric acid by 300 to 450 gallons per year, reduce its waste generation by 1,000 to 1,500 gallons per year, save an average of $4,555 per year on material and disposal costs, and improve worker safety.
