BioMate*

Biocides for Membrane Systems

Customer
Benefits

Features

• Highly effective in reducing bacterial growth
and slime build-up

• EPA registered, non-oxidizing biocides

• Specifically formulated to be compatible with

thin film polyamide, polysulfone and PVDF
membranes

• May be fed continuously, intermittently or in a
clean-in-place mode

• RO performance is enhanced when using
BioMate with Kleen* MCT membrane cleaners.

BioMate* MBC781 is an EPA-registered, non­oxidizing biocide used to sanitize reverse osmosis
(RO) systems and membranes. BioMate MBC781 is
fed continuously to the feedwater of these systems.
A treatment program that includes BioMate
MBC781 with other cleaning formulations from GE
Water & Process Technologies results in more effec­tive membrane cleaning and decreased cleaning
frequencies.

BioMate MBC881 is an EPA-registered, broad­spectrum biocontrol agent used as an intermittent
treatment to reduce slime build-up in RO mem­branes. For optimal results, the system should be
cleaned with Kleen* MCT882 and Kleen MCT511, or
Kleen MCT442 and Kleen MCT411 prior to the start
of the BioMate MBC881 treatment.

BioMate MBC2881 is an EPA-registered, non­oxidizing biocide used to sanitize RO systems and
membranes. BioMate MBC2881 may be used as an
intermittent treatment to the feedwater of these
systems. BioMate MBC2881 is applied by injection
into the feed stream during operation of the mem­brane plant while permeate is discharged to the
drain. Normal dosage time is 30 minutes per appli­cation.

Biogrowth Control Program

Biofouling is one of the most costly problems facing
the water treatment industry. The colonization of
naturally occurring microorganisms on membrane
surfaces shortens membrane element life and
inflates operating costs. Combating and eliminating
biofouling is essential for optimal membrane per­formance.

The Biogrowth Control Program can assist in con­trolling microbiological activity in a few simple
steps:

• Conduct microbiological tests and normalize RO
performance data

• Clean with Kleen MCT membrane cleaners

• Sanitize pipework and pretreatment equipment

with biocides

• Set up continuous, optimal injection of BioMate
biocide dosage and monitor bacteria levels and
system performance

• Record and normalize operating data.

The Biogrowth Control Program is highly effective in
reducing microorganism growth and slime build-up,
resulting in a significant increase in RO system per­formance.
