PRE-TREATMENT PH-3020D The PH-3020 system incorporates: a digital (dual) pH controller that monitors and adjusts both base and acid pH ranges; a circulation pump; and chemical peristaltic pumps. Once the pH set points (high or low) is satisfied, the permissive interlock system of the controller will provide an output signal for the purpose of downstream release and/or post processing of the water. (For additional details, refer to the pH Permissive product sheet) Balances water pH A balanced pH promotes: solids to settle out quicker; emulsified oils to become more buoyant; and some metals to precipitate.
