Kleen MCT511 

• Compatible with polyamide thin-film composite membranes
• Optimum results are obtained when used in conjunction with Kleen MCT882 and BioMate MBC881.
• Extremely effective against oils and many other organic compounds.
• Excellent results when used to clean biological matter and eliminate biological slime from the membrane surface.
• Buffered to maintain an effective pH over a range of dilutions.
• Enhanced performance at elevated temperatures.
• Liquid cleaner which allows shorter mixing time.
• Low foam formulation
• No adverse effects with repeated use.

Kleen MCT511 is a high pH liquid formulation designed to remove organics, silt, and other particulate deposits from polysulfone, fluorocarbon, and all polyamide thin film composite reverse osmosis (RO) and ultrafiltration (UF) membranes. The product is effectively used in nanofiltration (NF), and microfiltra-tion (MF) application. This product provides superior cleanings allowing longer run times.

TYPICAL APPLICATIONS

During the operation of a membrane separation sys-tem, 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 damage. 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 Betz representative can assist you with mon-itoring your system and determining when cleaning is advised.

Kleen MCT511 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 clean-er for scale removal,regular cleanings with Kleen MCT511 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 Betz representative for details.

Kleen MCT511 is not a biocide. If sterilization of the membrane and equipment surfaces is desired, con-tact your GE Betz representative.

APPLICATION

DO NOT USE Kleen MCT511 on cellulose acetate membrane. For optimum results, Kleen MCT511 should be used in combination with Kleen MCT882, and BioMate MBC881.
