Description
REVERSE OSMOSIS MEMBRANE CLEANER
RO membrane cleaners is specifically designed to remove iron fouling for silica. It also has effectiveness against calcium carbonate scaling. RXSOL-33-3304-025 performance can be enhanced by adding low / high ph cleaners to the cleaning solution although some minor ph correction may be necessary. It should always be used as recommended by the membrane manufacturer or equipment supplier, in respect to cleaning ph and temperature. it also contains organic dispersants that helps to break down colloidal clay deposits and imparts better efficacy to biocides by penetrating into films. it is specifically developed for removing iron, silica, metal silicates, metal oxides/hydroxides and other colloidal/particulate based foulants from ro membranes. It is also effective to remove calcium carbonate, calcium phosphate and silt.
As RXSOL-33-3304-025 is buffered, the cleaning solution will stabilise at pH 3.6.
High level of active substance.

Applications:
During the operation of a membrane separation system, organic materials as well as suspended solids in the incoming water can accumulate on the membrane surface. The presence of organic materials also provides an environment conducive to microbiological activity, which can result in microbiological fouling. Fouling from these species impedes the flow of water through the membrane. This can result in unacceptably low production, high operating pressure, or an excessive pressure drop in the system, which may lead to irreversible membrane amage. Additionally, accumulation of these foulants on the membrane surface can increase the amount of dissolved material passing through the membrane, resulting in product water of unacceptable quality. Before these foulants can accumulate to a level where product water declines or membrane damage can occur, they should be removed by a clean-in-place (CIP) off-line cleaning. Indications of the need for cleaning include a significant decrease in normalized permeate flow, a significant increase in pressure drop across the system (or individual stage), or an increase in the normalized salt passage, such that product quality is unacceptable. Your GE Infrastructure Water & Process Technologies representative can assist you with monitoring your system and determining when cleaning is advised. RXSOL-3304 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 cleanings with RXSOL-3304 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. RXSOL-3304 is not a biocide. If sterilization of the membrane and equipment surfaces is desired, contact your GE representative.
