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.
