Walchem ORP Controller Application

Blue Sphere recently completed a project utilizing ozone gas for disinfection of septic waste at a large industrial cable producer.

The system utilized a Walchem ORP controller, upgraded with an 4-20ma output card to ramp the ozone generators up and down to meet demand.  The Walchem controller output was tied to a custom control panel which included a PLC.  The ORP controller is mounted outdoors at the point of ORP measurement for simple calibration.

Walchem ORP controllers and ozone gas systems are available from Blue Sphere Water Technology for waste water and process water applications.
