Riverdale Mills of Northbridge, a manufacturer of welded wire mesh, received a TURI industry grant to reduce the use of hydrochloric acid, sodium hydroxide and ammonium hydroxide in their coating process.
Process Engineer Shuai Duo describes how he isolated the problem and designed a dual roller system that removes the acid from the surface of the wire mesh. This prevents dilution and contamination in the tanks. The acid that is removed is automatically recycled back to the tanks.
