Kleen* MCT524
Membrane Cleaner - FDA/GRAS Approved and Kosher
Features
 Highly effective cleaner for use with Thin Film
Composites (RO/NF) and hollow fiber mem-
branes (MF/UF).
 Excellent results are achieved when used to
remove organic foulants and biological slime
 Liquid product, which allows shorter mixing
time
 This formulation meets FDA requirements
(GRAS) for membrane process applications
 Improved results are obtained when used in
conjunction with Kleen* MCT403 or Kleen
MCT503
Description
Kleen MCT524 is a high pH liquid formulation
designed to remove organics, silt, microbiological
accumulation; and other particulate deposits from
Reverse Osmosis (RO), Nanofiltration (NF), ultrafil-
tration (UF) and microfiltration (MF) membranes
used in food applications. It is also an excellent
cleaner in pure water applications. This highly ef-
fective product provides superior cleanings result-
ing in longer system running time.
Typical Applications
During the operation of a membrane separation
system, organic materials and suspended solids in
the incoming stream can accumulate on the
membrane surface. The presence of organic ma-
terials also provides an environment conducive to
microbiological activity, which can result in micro-
biological fouling. Fouling from these species
impedes the flow through the membrane. This can
result in unacceptably low production, high oper-
ating pressure, or an excessive pressure drop in
the system, which may lead to irreversible mem-
brane damage. Before these foulants accumulate
to a level where product water flow or quality de-
clines or membrane damage occurs, they should
be removed through a clean-in-place (CIP) off-line
cleaning. Indications of the need for cleaning in-
clude a significant decrease in normalized perme-
ate flow, a significant increase in pressure drop
across the system (or individual stage), or an in-
crease in the normalized salt passage such that
product quality is unacceptable.
Your GE representative can assist you with moni-
toring your system and determining when clean-
ing is advised.
Kleen MCT524 contains a blend of solubilizing and
complexing agents designed to specifically
remove organic and particulate foulants from the
surfaces of the membrane. Used in tandem with
an acidic cleaner for scale removal, regular clean-
ings with Kleen MCT524 can help to preserve the
life of your membranes.
Depending on the nature of the fouling, a soak
period may be necessary for optimum results.
Consult your GE representative for details.
Application
For improved results in food applications, Kleen
MCT524 should be used in combination with low
pH cleaners such as Kleen MCT403 or MCT503.
