Biocides for Membrane Systems

Biocides for Membrane Systems

Most currently used membranes designed for reverse osmosis and nanofiltration processes, produced using thin-layer polyamide technology, are not compatible with chlorine and other strong oxidizers. For this reason, the supplied water must be subjected to dechlorination. This in turn carries the risk of growth of bacteria and microorganisms on the membarnes, resulting in lowering the device’s efficiency, or even polluting the permeate.

Description

Since there is no option to chlorinate the supply water of reverse osmosis units, it’s necessary to use other technologies to protect the membranes from microorganism growth and biofilm formation. The usual way to prevent these phenomena is through use of biocides.
Not all biocides are compatible with membranes, some in turn might leak to the permeate and cause it to become unusable. As such, selecting the correct technology is key to getting the desired effects while maitaining a clear permeate, and therefore the safety of the product created with it.
