Guidelines for the Use of Stainless Steel in Municipal Waste Water Treatment Plants (10076)
Stainless steel piping has become a standard material of construction for municipal waste water treatment plants built in the United States over the past 25 years. Since the late 1960s, over 1600 municipal waste water treatment plants have been built with stainless steel aeration piping, transfer piping for digester gas and sludge, sliding gates, valves, tanks, screens, hand rails, and other equipment. Stainless steel was selected originally over galvanized and painted carbon steel to reduce the higher maintenance and replacement cost associated with these less corrosion-resistant materials. Overall experience has been good to excellent.
