Quantifying and controlling each application uses an ORP probe and meter to measure the ORP as the IE-061 is added and a predetermined ORP set point is set to control the precipitation process. The equipment that we manufacture and are used in this precipitation process is our CFU, ABU, and MBU units. These units all have the ORP precipitation control process as an option to these precipitation and liquid/solids separation systems. We also make the ORP control systems available separately.
