What is the maximum filtration rate for pressure filtration?

The maximum filtration rate for pressure filtration is typically in the range of 2 to 3 gallons per minute per square foot. This rate is widely accepted in the water treatment industry because it balances effective filtration with the potential for filter media compaction and clogging. Exceeding this range can lead to a variety of operational issues, including reduced filtration efficiency, increased pressure drop, and the likelihood of breakthrough, where contaminants pass through the filter instead of being captured.

Understanding this optimal range is crucial for operators to ensure that water treatment processes remain effective and compliant with safety standards. By adhering to these filtration rates, facilities can maintain better overall water quality, increase the lifespan of the filter media, and minimize maintenance needs.
