Microbial control in Reverse Osmosis Systems

Reverse osmosis (RO) is a membrane technical filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective," this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.

The Reverse Osmosis is a wonderful invention for purifying water, but all face a problem: Biological pollution on the carbon filter, membranes, tanks and pipe system.

Special care is required to choose the oxidizing agent, to prevent damage to the membrane.

With it`s unique characteristics eOxide LQ 85 is a very appropriate product for this purpose. eOxide LQ 85 is highly effective against biofilm, the main reason for loss of efficiency and reduced membrane life in RO systems. eOxide LQ 85 will keep the sysem clean without damaging the membrane and the equipment.
