RO Biocide
Biocide for Reverse Osmosis Systems, RO Biocide
RXSOL RO Biocide is a concentrated non-oxidizing biocide based on glutaraldehyde, formulated for microbiological control in industrial water-treatment systems and RO membrane installations.
It is designed to control bacteria, fungi and algae and to reduce biological growth, slime and biofilm formation in RO feed systems, pipelines, pretreatment equipment and associated water-treatment equipment.
Water injection system Biocide
Unlike chlorine and other oxidizing biocides, glutaraldehyde does not rely on oxidation as its primary antimicrobial mechanism. However, glutaraldehyde-based products should not automatically be assumed to be compatible with every polyamide RO membrane. Published membrane literature identifies aldehydes, including glutaraldehyde, as chemicals that can cause irreversible flux loss under some conditions. Therefore, the product should be used in RO systems only at concentrations and exposure conditions validated for the specific membrane.
Key Features of RXSOL Biocide RO Systems

Procedure of Biocide used in Reverse Osmosis Systems
It is a reactive non-oxidising biocide. It reacts with cellular proteins and other biological structures, interfering with essential microbial functions.
The general action can be represented as:
RXSOL RO Biocide→ penetration/contact with microorganism → reaction with cellular proteins → loss of cellular function → microbial inactivation
It is therefore fundamentally different from oxidizing biocides such as chlorine, sodium hypochlorite and bromine.
