Controlling Sulfate Scaling In RO Systems
Controlling sulfate scaling in reverse osmosis membranes is critical to the longevity of the membrane elements and successful operation of the RO system. Historically, membrane elements with barium sulfate, strontium sulfate or calcium sulfate were unable to be cleaned requiring costly membrane replacement. In recent years, great strides have been made both in controlling and cleaning sulfate scaling.
Controlling sulfate scales is more difficult than controlling calcium carbonate scaling. Simple pH adjustment through the addition of acid into the feed water to the RO was fairly successful at controlling calcium carbonate scale. The primary acid used for pH adjustment is sulfuric acid, which increases the level of sulfates in the feed water, which in turn increases the scaling potential for sulfate scales. Increased recovery requirements for RO systems intensified the scaling potential even more. It became evident that successful operation of RO systems at higher recoveries would require chemicals designed to inhibit various types of scaling and fouling. With proper dosing, a well-engineered scale inhibitor can successfully control scaling and fouling.
Once that it had precipitated out of solution, sulfate scale was impossible to clean out of the membrane. High pH cleanings had no affect and low pH cleanings were equally unsuccessful. The fact that the sulfate scale would not dissolve or go back into solution, made cleaning the membranes a fruitless task. Membrane replacement was inevitable. In recent years, new membrane cleaning formulations have been developed that combine organic acids with specific dispersants which has the ability to soften the sulfate scale enough to allow the flow of the cleaning solution to remove the scale as a semi-solid material which will trap in the cleaning skid filters.
For the greatest success in controlling sulfate scaling in an RO system, it is necessary to implement the use of a quality scale inhibitor, formulated for reverse osmosis systems and engineered for control of high levels of sulfate scales. Additionally, a new generation membrane cleaner with the ability to remove sulfate scale should be used for the low pH cleanings. It is always advisable to follow a low pH cleaning with a high pH cleaning using a cleaner formulated for use in RO systems.
