What is the recommended rate of filtration for a vacuum diatomite filter?

The recommended rate of filtration for a vacuum diatomite filter is 1-2 gallons per minute per square foot. This range is crucial because it balances the efficiency of the filtration process with the integrity of the filter media. A filtration rate that is too high could lead to insufficient removal of solids, which compromises the effectiveness of the filtration and may lead to issues such as filter cake formation that can hinder performance.

Operating within the 1-2 gpm/ft² range ensures that the diatomaceous earth filter can adequately separate particulates from the liquid being filtered. This rate allows for optimal interaction between the liquid and the diatomaceous earth, ensuring thorough filtration while maintaining the filter's operational integrity. Understanding this filtration rate is essential for achieving clean water results and for the effective operation of facilities performing material separation.
