RO Membrane Cleaning Chemicals

It is normal to see performance degradation when using reverse osmosis membranes. The decrease in membrane performance manifests itself as an increase in the pressure applied to the membranes and a decrease in the demineralized product water obtained from the membranes. In this case the membranes need to be chemically cleaned with certain periods. Chemical cleaning of membranes is done using specially prepared acidic and basic chemicals. Acidic cleaning for calcified membranes, alkali cleaning for organically contaminated membranes. Membrane cleaning is usually done first as acidic cleaning followed by alkali cleaning. This sequence and the process of exposing the membranes to the cleaning solution may vary depending on the contamination density of the RO membranes. When the reduction of the performance of RO membranes reaches 15%, the membrane cleaning process must be carried out without delay.
If reverse osmosis membranes are responsible for the increase in the outlet water conductivity, free chlorine etc. in the raw water structure. Oxidant substances may be present. In this case, it will not be a positive effect of chemical washing on RO membranes. In such a case, the membranes will need to be replaced.

RO Membrane Cleaning

RO membranes' cleaning is usually done firstly by acidic cleaning and then by alkali cleaning. This sequencing and the process of exposing the membranes to the cleaning solution can vary depending on the fouling intensity of the RO membranes. When the decrease in the performance of RO membranes reaches 15%, membrane cleaning should be done without waiting.

The reason for the increase in the RO product water conductivity can the oxidative chemicals such as free chlorine in the raw water structure. In this case, chemical washing of the RO membranes will not have a positive effect. In such a case, the membranes will need to be replaced.
