Membrane Cleaning Chemicals lie at the heart of any reverse osmosis
system, it is therefore essential that the membranes are maintained
in a good clean condition and this should be considered to be an
important part of any reverse osmosis maintenance program. Effective
cleaning usually requires some knowledge of the type of foulant and
the cleaning options available.
It is essential to clean RO membranes at an early stage of
fouling. It is often difficult to clean excessively fouled membranes
and irreversible damage may occur during the cleaning process.
Cleaning with a suitable ROC membrane cleaner is strongly
recommended when one or more of the following parameters change by
10 – 15%, after data normalization:
An increase in product water conductivity or salt passage.
An increase in pressure drop across the plant.
An increase in feed pressure.
A decrease in normalized permeate flow (NPF) output or flux.
If any of the above performance parameters deteriorates by
more than 30%, it may be impossible to recover plant performance by
routine cleaning practices using a suitable membrane cleaner. Our
Chemicals are effectively formulated and cleaning includes High pH
and Low pH Cleaners with inhibitors.
Our Product is a proprietary blend of mono-polymers and cleaning
compounds. The cleaning compounds attack the organic and inorganic
fouling. The polymers protect the membrane surface from damage which
can be caused by the harmful cleaning chemicals.
Salient Features :
High purity product - synthetic grade.
Fast acting - effective in removing a wide range of scales
Does not contain any harmful metal corrosion inhibitor which
might adversely affect membrane performance.
Usage Tips :
When adjusting the ph of cleaning solutions or plant feed
water always refer to membrane manufacturer's or oem's instructions.
Our cleaners are used in dilution with potable water that is
free of residual chlorine or other oxidizing agents to make the
cleaning solution. The cleaning solution must be stirred to avoid
localized variations in ph. The cleaning solution is prepared by
addition of recommended dosage of product. After adjusting the ph of
solution as desired, the cleaning solution is then circulated
throughout the system without exceeding pressures, temperatures and
flow rates recommended by the membrane manufacturer. Cleaning
efficacy can be further improved by heating the cleaning solution
and alternately circulating the solution for 15 minutes and then
soaking the membranes for 15 minutes. This should be repeated as
many times as necessary. Dosage depends on severity of fouling.
We have following types of RO Membrane Cleaners.
1. Low pH R.O. Membrane Cleaner
2. HIgh pH R.O. Membrane Cleaner
