What is the flow rate for DE filters?

The flow rate for diatomaceous earth (DE) filters is generally recognized as 2.0 gallons per minute per square foot (gpm/ft²). This standard is based on the optimal performance of DE filters, which are designed to efficiently remove small particles from water by utilizing the unique properties of diatomaceous earth, a naturally occurring sedimentary rock.

At this flow rate, DE filters can effectively trap particulates while maintaining sufficient water flow, ensuring clarity and sanitation in filtration systems, such as in swimming pools or industrial applications. Deviating from this flow rate may lead to compromised filtration efficiency or increased pressure on the system, potentially causing operational issues.

Understanding the specifics of this flow rate is crucial for anyone working with water filtration systems, as it directly impacts the effectiveness and longevity of the filters in use.
