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.

 

²The permeability was measured under test conditions with clean water at 20 °C (68 °F) and a Δp of 1 bar (14.5 psi).

 

Regeneration

T Series Filter Sheets may be rinsed with clean water (in the forward or reverse direction) to increase throughput and to optimize economic efficiency. Optimal regeneration of filter sheets installed in a plate and frame filter may be achieved with serial rinses of warm water followed by hot water. An example protocol is shown below.

 

• Rinse with warm water (60 °C / 140 °F) for 15 minutes
• Rinse with hot water (70 – 80 °C / 158 – 176 °F) for 8 – 10 minutes

 

The rinse flow rate should be equivalent to the filtration flow rate with a back pressure of 0.5 –1 bar (7.2 –14.5 psi).

³The actual time required may vary as a function of the process conditions.

 

Filtration Guidelines

Please contact Pall for recommendations on your specific filtration process as results may vary by product, pre-filtration and filtration conditions.

For additional operating guidelines, including rinsing of sheets prior to use, please refer to instructions provided by Pall.
