PH PERMISSIVE CONTROL SYSTEM
BALANCES WATER PH
The PH-3020D system incorporates: a digital (dual) pH controller that monitors
and adjusts to both base and acid pH set points; a circulation pump; and chemical
injection peristaltic pumps. Once the pH set points (high or low) are 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.
