Manual Jet Wash

The Milton Roy Model SC5200 Streaming Current Detector (SCD) is an on line electrokinetic charge analyzer that measures the net ionic and particle surface charge in a chemically treated water or wastewater sample. The SCD allows continuous monitoring and control of the coagulation process, thereby providing:
Combines a SCD and process controller in a single unit, eliminating the need for additional control instruments in closed-loop dosing applications.
Once installed, the SC5200 is immediately ready to control coagulant dosing pumps or control valves that accept a 4–20 mA process signal.
Features the latest generation of Streaming Current Technology, delivering superior performance based on extensive research and development.
Incorporates key enhancements in electronics, sampling systems, and overall design for greater process stability, faster response, reliable operation.
Builds on over a decade of successful SCD applications in water treatment, with innovations that enhance operational efficiency and control accuracy.
A SCDs designed for wastewater treatment, enabling effective coagulant feed control for belt presses, centrifuges, and dewatering equipment.

The Automatic Jet Wash is an optional patented sample cell cleaning system available on Milton Toy SCD’s. The system 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.
