Fouling and scaling can be especially problematic in strainers and filters as this equipment typically consist of a perforated or mesh screen that captures solid particles while allowing the fluid to pass through. When these screens become contanimated with fouling or scaling, they cannot function effectively. Implementing advanced clean-in-place (CIP) technology, particularly ultrasonic CIP, can effectively address these issues.
CIP systems that use ultrasonic technology truly enhances cleaning by effectively removing and preventing the buildup of minterals, biological material and contaminants on the strainer screen. Implementing this solution will allow you to maintain optimal strainer and filter performance.
When solid particles accumulate on a perforated or mesh screen, the open area is reduced, causing flow restrictions. These fouling particles can include debris, sediment, biological material, and other suspended solids present in the fluid. Over time, all this buildup leads to increased pressure drop, reduced flow rates, and diminished strainer performance. Additionally, fouling may create an environment conducive to bacterial growth and biofilm formation. Scaling causes a similar consequence through a build up of minerals like calcium, magnesium, or silica. This can be a particular problem for strainers as this is the very thing the strainers are working to filter out of water.
Factors contributing to fouling and scaling in strainers include:
The composition of the fluid being filtered plays a significant role. Fluids with high levels of suspended solids, organic matter, or dissolved minerals are more likely to cause fouling and scaling in strainers.
