Suspended solids and colloidal materials cause membrane fouling in RO system. In order to take some measure of the degree of this fouling problem, SDI test is required.
RO element specifications usually call for the SDI value to be below 5.
Water sources in a RO system often change their water quality and this often needs to be done weekly or monthly.
Features:
According to the ASTM D4189-07 Norm
Available in Seawater and Common Water Type
In-Field flow calibration
Uniform water distribution and complete venting
Quick and convenient
Easy installation and simple tools
Lightweight and portable
Special regulator for stable pressure
Excellent seal of advanced O-ring
