SC2200 STREAMING CURRENT DETECTOR TheMUIon Roy Mcdel SC22CX) Streaming Current Elector ©CD) Ls an on line dectrokinetk charge analyzer thai measures the net ionic and particle surface charge in a chemically treated water or wastewater sample. The SCD allows continuous rnonitoring 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 automatic operation The SC2200 is designed to be used with the RM6200 Remote Monitor Station or the RC7200 Remote Controller Station. Jt is a complete SCD that can be directly linked with computer systems, recorders, or suitable process controller* Mounted remotely, it can be separated from the monitor or control sta* tion by up to 3000 feet without affecting signal reliability. Special coaxial cable is not required. The 5C2200 represents the most advanced level of Streaming Current Technology available today. The 5C2200's electron- ic*, sampling sytfern 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 SC2200 incorporates a number of key improvements that provide even greater stability, response, and improved operation over previous successful designs. In addition, the SC2200 is the first of a new generation of SCO's designed to operate In wastewater treatment. Special probe designs and electronic advances have opened the door to controlling coagulant feed to belt presses, centrifuges, and other dewatehng equipment. JET WASH SAMPLE CELL CLEANING The Automatic Jet Wash U an optional patented sample cell cleaning system available on Milton Roy SCO's. The system is designed to maintain cell cleanliness and signal reliability by automatically flushing the sample cell on a predetermined cycle. Rushing 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. 5C2200 MODEL SELECTION GUIDE Output Signal Probs> Cleaning Options 0 = Standard Manual Jet Wash Operating Voltage Probe Configuration F ■ Slar>o>d Flow Through Other Options Automatic )et Wash is factory set at 30 seconds every 2 hours, jet Wash timing is field adjustable.
