SUPRApak™ ZD Series Depth Filter Modules

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 and beverage applications.

 

Features	Benefits
100% pure cellulose depth filter media: no inorganic components	Very low impact on color and flavor Very high purity, low extractables, low ion release Up to 50% less water consumption for conditioning and regeneration
Highly fibrillated cellulose fiber matrix	Very strong filtration media Easy to regenerate High hold up volume for long filtration cycles Very good particle and microbiological reduction
SUPRApak design “edge flow” Technology	Optimized use of depth filter matrix Very high filtration area per module Compact module design Enabling enclosed, more hygienic sheet filtration

Conditioning

 

Prior to use, it is recommended to rinse the filter with clean water at ambient temperature with > 50 L/m².

 

Regeneration¹

 

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.

1. Rinse with cold water (ambient temperature) for 5 min.
   
2. 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).

 

¹ 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.

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