Automatic SDI Monitors – EZ SDI

Product Description

–The EZ™ and Enhanced SDI monitors
automatically and consistently monitor the silt
density index of RO feedwater. Monitoring the
SDI is very useful to determine fouling problems
before the membranes need replacement.

–The EZ SDI™ is microprocessor controlled and
fully automatic, allowing operators to quickly and
regularly check the effectiveness of the RO
pretreatment system.

–The EZ SDI™ is designed for permanent
installation. In order to prevent stagnant
conditions in the sample line, the monitor
continuously allows a side stream of sample to
flow through the monitor up to the point where the
sample enters the filter. A specially designed
orifice controls the rate of this side-stream flow.
The orientation of the flow control orifice also
allows air in the sample line to be separated from
the sample before the sample enters the filter
holder.

–The EZ SDI unit performs one test at a time, while
the EZ SDI-4 performs up to 4 tests between filter
change-outs.
