What is the filter rate for Diatomaceous Earth (D.E.) filters?

The filter rate for Diatomaceous Earth (D.E.) filters is typically around 2 gallons per minute per square foot (gpm/sq ft). This specific filtration rate is important because it helps maintain the effectiveness of the filter while preventing issues associated with overloading the system. D.E. filters are known for their ability to trap very fine particles and contaminants, providing high water clarity and quality. Operating at the correct filter rate ensures that the D.E. medium can effectively capture debris while allowing for adequate water flow, preventing pressure buildup that could damage the filter system. Thus, understanding the proper filter rate is crucial for the efficient operation of a D.E. filtration system in swimming pools.
