Navigating the Complexities of Silica in RO Systems
Silica scale is one of the most difficult scales to control, prevent, and remove from a reverse osmosis (RO) membrane system. Once on a membrane, it is very difficult to remove and requires specialized cleaners. It is important to understand the different types of silica found in water and how silica scale forms to prevent scaling events.
