The verification report found in this document reviews the performance of the Hydromatix 786E Ion Exchange Rinsewater Recycling System. The 786E system is used in various Metal Products and Machinery (MP&M) industries to treat rinse wastewaters, and features special provisions to minimize the regenerant waste volume produced. The 786E system treats rinse wastewaters by removing the cations and anions resulting from electroplating, cleaning, and anodizing operations, and minimizes the regenerant wastes produced by reusing portions of the regenerant waste solutions. Regeneration of ion exchange resins consists of a series of acid and base rinses which result in restored resin functionality. The regeneration technology utilizes a process logic controller (PLC), sensors, and associated plumbing for regeneration of the resins and for collection and reuse of portions of the regenerant waste solution. This verification report quantified the rinse wastewater treatment by measuring the volumes and concentrations entering and leaving the 786E system, and characterized the regeneration procedures by measuring the regenerant waste volume produced and by determining the regeneration efficiency.
