SC4200 STREAMING CURRENT DETECTOR The Milton Roy Model SC42CO Streaming Current Detector <SCD) is an on line electrokinetic charge analyzer that mea* sures the net ionic and particle surface charge in & chemically treated water or wastewater sample. The SCDallows con- tinuous monitoring and control of the coagulation process, thereby providing: • Consistent water quality * Uniform chemical dosing under varying conditions • Reduced chemical costs • Reduced manual supervision and/or automate operation The SC4200 represents the most advanced level of Streaming Current Technology available today. The SC42CC5 electron- ire, sampling system and overall design are the direct result of years of studies and research and development aimed at advancing the technology. Though SCO's have been an ac- cepted part of water treatment for over a decade; the SC420Q incorporates a number of key improvements hat provide even greater stability, response, and improved operation over previous successful design* In addition, the SC4200 is the first of a new generation of SCO's designed to operate in wastewater treatment- Spedal probe design* and electronic advances have opened the door to controlling coagulant feed to belt presses, centrifuges, and other dewatering equipment. JET WASH SAMPLE CELL CLEANING The Automatic Jet Wash t± an optional patented sample cell cleaning system available on Milton Roy SCO's. The sy&tem Is designed to maintain cell cleanliness and signal reliability by automatically flushing the sample cell on a predetermined cycle. Flushing is accomplished by injecting water at high velocity through the bottom of the sampling cell, which scours the cell surfaces and forces contaminants into the sample stream drain. Cleaning frequency is field adjustable to suit the application. Signal output Is automatically locked during the cleaning cycle to ensure control stability.
