These figures have been determined in accordance with in-house test methods and the methods of the Technical / Analytical Work Group within the European Depth Filtration Association.
1The permeability was measured under test conditions with clean water at 20 °C (68 °F) and a Δp of 1 bar (14.5 psi).
Regeneration
Depending upon the application and the nature of the adsorbed contaminants, AKS series filter sheets may be regenerated by means of rinsing with clean water in the forward direction. However, the achievable regeneration efficiency must be determined by monitoring filtrate quality.
Maximum backpressure during all operations is 0 bar. Any backpressure will cause damages to the sheet media.

General Instructions for Use
In order to maximize the required adsorption of impurities, particle filtration must occur upstream of carbon-impregnated filter sheets.
Filtration Guidelines
Typical flux rates used on food and beverage fluids are 150-250 L/m2/h (3.7-6.2 gal/ft2/h).
Higher fluxes may be possible according to the application. Due to the various factors, which may affect the adsorption process, Pall recommends an initial scaled-down testing as a reliable method of qualifying filter performance.
For additional operating guidelines, including rinsing of sheets prior to use, please refer to instructions provided by Pall.
