Product Description

RizonSDI ^® Multi-channel Fully Automatic SDI Instrument It is an online control system designed for continuous and automated desalination processes and other water treatment projects. It can achieve automatic or remote monitoring; precise testing is achieved through safe and economical operation, replacing the cumbersome manual operation and avoiding human error.

The pollution density index SDI value is an important parameter of the water quality index of the reverse osmosis system and is the main means of testing whether the effluent of the pretreatment system meets the requirements of the reverse osmosis feed water. Its size is crucial to the service life of the reverse osmosis system.

Product Features

Fully compliant with ASTM D4189-07 standard
24 hours, 365 days a year continuous automatic operation
Can measure 1-4 different water qualities as needed
It can automatically measure at a fixed cycle according to the set time without external signals; it can also be remotely monitored by external input control signals.
4-20mA analog signal output test results, switch signal output alarm
IP65 enclosure protection level
Alarm types include temperature alarm, abnormal air pressure alarm, diaphragm shortage alarm and pollution index overlimit alarm
Equipped with HSDI-0645-MCE membrane roll, each roll can be tested up to 80-100 times
Optional communication protocol and mobile phone APP function to realize "smart factory"

Product Advantages

Online real-time monitoring of SDI value, large LCD color liquid crystal display
With power-off protection, digital filtering technology, and strong anti-interference ability
Inquire historical and system alarm records at any time
Mobile phone APP function, real-time monitoring can be achieved by mobile phone
When the inlet pressure is less than 3 bar, a booster pump can be configured

Application Areas

Seawater desalination
Municipal water treatment
Petrochemical
Power
Laboratory
Online monitoring
