SC5200 STREAMING CURRENT DETECTOR
DESCRIPTION
The Milton Roy Model SC5200 Streaming Current Detector
<SCD> is an on line electrokinetic charge analyzer thai mea-
sures the net kmk and partide surface charge in a chemically
treated water or wastewater sample. The SCD allow* con-
tinuous monitoring and control of the coagulation process,
thereby providing;
* Consistent water quality
* Uniform chemical dosing under varying conditions
* Reduced chemical costs
* Automatic operation of the treatment process
The SC520O is a complete SCD and process controller in one
package Once installed, it is ready to control any coagulant
dosing pump or control valve that accepts a 4*20 mA process
signal. No other control instruments are required for a dosed
loop control.
The SC5200 represents the most advanced level of Streaming
Current Technology available today. The SC520Cs electron-
ics, sampling system and overall design are the direct result
of years of studies and research and development aimed at
advancing the technology. Though SOD'S have been an ac-
cepted pan of water treatment for over a decade, the SC5200
incorporates a number of key Improvements that provide
even greater stability, response, and improved operation
over previous successful designs
In addition, the SC5200 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 dewatcring equipment.

JET WA5H SAMPLE CELL CLEANING
The Automatic VL Wash is 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 Hushing the sample cell on a predetermined
cyde. Rushing is accomplished by Injecting water at high
velocity through the bottom of the sampling cell, which
scours the cell surfaces and force* 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.
