Filtration Optimization

Filtration is one of the most important steps in water treatment today. Proper care and maintenance is key to meeting new compliance regulations and extending the life and performance of your filtration system. Check out Bob Cashion’s article, Using Media Inspection & Maintenance for Filtration Optimization on Water Online.

Cashion’s article provides insight to the overall importance of the filtration process and how the process has changed with the current importance being placed on TOC reduction and disinfection byproduct (DBP) regulations.  Mechanical applications of the filtration process for both gravity and pressure filters are examined to provide a better understanding of the importance of operations and maintenance practices for optimized performance of filtration systems.

Proper care of filtration media is discussed in depth to show the contamination issues that occur and the effects biofilm growth can have on overall water quality. A cost analysis chart shows the difference in costs between media cleaning practices verses complete media change-out and how it can become a maintenance expense rather than capital improvements.

Furthermore, practical solutions utilizing Blue Earth Products’ chemical cleaning solutions are discussed in detail and completed case studies from three various filtration facilities are used to exemplify the cost savings of media cleaning over media change-out.
