Pall’s SUPRApak™ Zero DE (ZD) module Series is a unique combination of Pall’s SUPRApak design for sheet based modules and a pure cellulose depth filter sheet media for Food and Beverage applications. The filter has been designed to give excellent filtration performance and lower filtration costs.
The SUPRApak ZD Series combines a 100% cellulose depth filter sheet matrix and Pall’s SUPRApak design with the unique “edge flow” principle. The SUPRApak ZD filter media was developed to meet the need of the Food and Beverage Industry for filter sheet media, based on 100% pure cellulose fiber matrix material without any content of Diatomateous Earth (DE) or Perlite. SUPRApak ZD filter modules are available in multiple grades, suitable for microbial reduction, fine filtration and clarifying filtration in various Food & Beverage applications.

Prior to use, it is recommended to rinse the filter with clean water at ambient temperature with > 50 L/m².
SUPRApak ZD filter modules may be rinsed with clean water only in forward direction to optimize total throughput and economic efficiency. Optimal regeneration may be achieved with several rinses of cold water followed by warm water. An example protocol is shown below.
a. Rinse with cold water (ambient temperature) for 5 min.
b. Rinse with warm water (max. 60 °C / 140 °F) for 10 min.
Rinsing flow rate should be max. 1 ½ of the filtration flow rate with a counter pressure of 0.5-1 bar (7.2-14.5 psi).
Avoid any backpressure as it destroys the module. Water used for forward flow flushing should be particle-free, and if the filter will not be sterilized prior to re-use the water should be free of microorganisms. The actual time required may vary as a function of the process conditions.
