Acid-metal processes operate at an optimum acid concentration. Contaminant metal ions are allowed to increase to a point where the efficiency of the process becomes unfavorable. When reduced productivity is due to process stoppages in order to dump acid solutions contaminated with metal-salts,or suspended solids, the Scanacon acid management system SAR-ModuFlex or MiniFlex and SAFU, CycloSAFU or ASRA filtrations systems offer the opportunity for continuous production without outages to dump waste acid, clean process tanks and piping and replenish with fresh acids.

Increased productivity by gaining control over the main variables that govern the pickling, etching or milling reaction ensures consistent and repeatable processing times. In some cases, reductions of 40% in processing times can be achieved by optimizing circulation rates, resulting in significant increased productivity.
