What Causes High Pressure Drop in Liquid Filtration?

Pressure drop is an important signal in liquid filtration. A rising pressure drop can mean that filter media is collecting particles as expected, but it can also indicate undersized equipment, too fine a micron rating, high solids loading, high viscosity, or blocked filter media.

Key Selection Questions

• What liquid is being filtered?
• What particle size needs to be removed?
• What flow rate and pressure drop are acceptable?
• How often can the filter media be replaced or cleaned?
• Is the filter used for pre-filtration, process filtration, or final filtration?

For final product selection, review the application with real operating conditions rather than relying on one specification alone.
