SUPRAdisc II™ ZD Series Depth Filter Modules

Pall’s SUPRAdisc™ II Zero DE (ZD) module Series is a unique combination of Pall’s SUPRAdisc II design for lenticular 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 SUPRAdisc II ZD Series combines a 100% cellulose depth filter sheet matrix and Pall’s SUPRAdisc II design with its patented Inside-Outside Separator Technology that differentiates from classical stacked disc lenticulars in their filtration and handling characteristics. The SUPRAdisc II 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 use of Diatomateous Earth (DE) or Perlite. SUPRAdisc II ZD filter modules are available in multiple grades, suitable for microbial reduction, fine filtration and clarifying filtration in various Food & Beverage applications.

Specifications

Conditioning

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

Regeneration2

SUPRAdisc II ZD filter modules may be rinsed with clean water (in forward or reverse direction) to increase total throughput optimizing economic efficiency. Optimal regeneration of SUPRAdisc II ZD modules 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 1 ½ of the filtration flow rate with a counter pressure of 0.5-1 bar (7.2-14.5 psi).

2When rinsing in the reverse flow direction it is critical to control particulate and microbial levels of the rinsing water, so that the filtrate side of the sheet media is not contaminated. Water used for reverse flow flushes should be particle-free, and if the filter will not be sanitized prior to re-use the water should be free of microorganisms. The actual time required for optimal regeneration 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.
