10. Rouge Monitor is designed to improve facility operations in ultra pure water systems by enabling the user to directly monitor the rouging rate or corrosion rate and assist in determining when re passivation is required to prevent unacceptable levels of contaminants in the water These contaminants are mostly iron chrome and nickel compounds resulting from a small amount of corrosion of the stainless steel pipework and vessels Corrosion of the stainless steel in these ultra pure water systems is kept very low through a passivation process which may need to be re done at intervals to maintain the passivation Once the passivation layer becomes depleted through continued operation of the system the corrosion rate will begin to increase as will the rate of contamination of the system by the corrosion products producing rouge in the ultrapure water The Rouge Monitor provides a low cost method of measuring the rouging rate through a very sensitive electrochemical measurement method based on a special version of the RCS Corrater range of instruments specifically designed for these very low conductivity waters Equipment Configuration The Rouge Monitor comprises of three pieces a probe that is inserted into the ultra pure process stream a local electrochemical transmitter and a remote display control and data logging unit The probe has two stainless steel electrodes glass sealed into a stainless steel probe body and welded to a sanitar
