Scaling, Membrane Fouling & Chemical Cleaning in RO Plant

Monitoring overall plant performance on a regular basis is an essential step in recognizing when membrane elements are becoming fouled. Performance is affected progressively and in varying degrees, depending on the nature of the foulants. RO cleaning frequency due to fouling will vary by site. A rough rule of thumb as to an acceptable cleaning frequency is once every 3 to 12 months.
 

RO pretreatment
 

If you have to clean more than once a month, you should be able to justify further capital expenditures for improved RO pretreatment or a redesign of the RO Operation. If the cleaning frequency is every one to three months, you may want to focus on improving the operation of your existing equipment, but further capital expenditure may be harder to justify.

It is important to clean the membranes when they are only lightly fouled, not heavily fouled. Heavy fouling can impair the effectiveness of the cleaning chemical by impeding the penetration of the chemical deep into the foulant and in the flushing of the foulant out of the elements. The Training Program provides a practical understanding of chemical cleaning, which can be expensive, time-consuming, and decrease plant performance when it is frequently performed, and learn how to use suitable chemical cleaning. This session will also teach you the most effective and low-cost chemical cleaning.
