SS/MLSS Analyzer



Overview

SMART series intelligent multi-parameter universal controller has high accuracy, its unique professional design can be applied in water, chemical, pharmaceutical, food and hygiene in the production process of the most extreme physical and chemical environments. SMART series intelligent multi-parameter universal controller has modular bus structure, highly scalable functionality, high reliability and comfortable operation.


Measurement principle

Turbidity/Suspended Solids Concentration refers to the degree of hindrance of suspended solids in water to light transmission.

Turbidity means that when a beam of light passes through a liquid medium, part of the light will be refracted on the surface of the insoluble particles. The degree of light refraction is related to the size and shape of the particle. The intensity of the scattered light has a certain proportional relationship with the size of the particles.

When a beam of light passes through the suspended object to be measured, the light is absorbed by the measured object, and only a small part of the light is transmitted through after reflection and scattering. According to Lambert-Beer law lnS = CK * MLSS, the concentration of suspended matter has a certain proportional relationship with the transmittance of transmitted light.


Typical application

▲Source water monitoring

▲Filter backwash detection

▲Filter monitoring

▲Driking-water quality monitoring

▲Separation process monitoring

▲Cooling water monitoring

▲Circulating water detection

▲Sludge treatment monitoring

▲Aeration tank monitoring


Feature

Installation

▲Avoid bubble interference

▲The inclined surface of the probe faces the direction of the fluid, and the smooth sensor surface has a self-cleaning effect

▲Keep a distance of 20cm from the side wall or bottom, try to avoid the interference caused by the side wall

▲It is forbidden to install where suspended solid particles are easy to settle


Calibration

The turbidity measurement with NTU or FNU as the unit of measurement does not require calibration.


Application Case

★Chlor-alkali: monitor the working status of the secondary brine filtration membrane

★Sewage: inlet, sludge treatment, dehydration, aeration tank and outlet, detection and control of water treatment process

★Drinking water: detect and control all steps of the drinking water treatment process
