SUPRApak™ Plus PW Series Modules

Developed from traditional depth filtration technology, SUPRApak modules efficiently combine the filtration mechanisms of surface filtration, depth filtration and adsorption. Highly unique to their design is an entirely new flow configuration, based on the "edgeflow" principle.

Seitz® filter sheet material is wrapped around a central, permeable core. Feed and filtrate channels provide a fluid flow path resulting in maximum utilization of the sheet material, to provide highly efficient contaminant removal and a cost-effective enclosed system alternative to flat sheet filtration. New to the SUPRApak PW Series is an improved layer to layer sealing which offers the following features and benefits:

 

Features	Benefits
Flow configuration based on "edge flow" principle	Up to 6 times higher throughput compared to classical sheet filtration, resulting in longer process uptimes1 Increased adsorption capability and excellent filtrate quality
Sealing line technology	Higher mechanical stability Modules can be steam sanitized Higher dp stability and therefore higher total throughput
Enclosed filtration system	Increased process safety and product quality No drip losses Minimal operator exposure to process fluids
Drainable, low hold-up volume assembly	Higher product yield; lower cleaning costs
High filtration capacity in compact design	Small footprint
Simple, quick installation and servicing	Reduced labor and maintenance costs

Typical applications are found in many fluids in the food and beverage industry.

 

Final Filtration	Enzyme solutions, Sweeteners
Polishing filtration	Sweeteners, Beer, Wine, Flavors, Thin liquor gelatin, Yeast extract, Vinegar
Clarifying filtration	Beer, Wine, Enzymes, Flavors, Thin liquor gelatin, Polyols, Edible oils
Coarse filtration	General particle removal

Technical Information

Operating Characteristics in Compatible Fluids³

Module Size	Grade	Max. Operating Temperature
SUPRApak M, L	PW 5200–PW 7100	80 °C (167 °F) / 8 hours4

³ Compatible fluids are those which do not adversely affect the filter materials of construction.

Module	Dry Weight	Wet Weight Ash	Content5
SUPRApak M (PW 5200 – PW 7100)	5.1 – 5.6 kg (11.2–12.3 lbs)	15.5 –16.5 kg (34.1–36.3 lbs)	40 – 54%
SUPRApak L (PW 5200 – PW 7100)	11–12 kg (24.2–26.4 lbs)	25 – 30 kg (55 – 66 lbs)	40 – 54%

⁵ These figures are determined on typical finished articles. Values differ for individual PW grades. Ash values for the filter sheets in individual batches are available on request.

 

Many applications in the food and beverage industry are ideally suited to the use of SUPRApak technology, resulting in significant commercial and technical advantages.

 

Sanitization⁶

Method	Temperature	Time/Cycles6
Hot Water	85 °C (185 °F)	20 cycles @ 20 min each
Steam	125 °C (258 °F)	10 cycles @ 20 min each

⁶The actual time required may vary as a function of the process conditions. Laboratory tests were carried out up to 10 cycles. Actual field experience shows more cycles are achievable, coupled with proper filtrate quality monitoring.

 

Rinsing⁷

Module Size	Rising Volume/Module	Recommended Flow Rate
SUPRApak M	140 liters (37 gal)	1.5 times filtration flow rate
SUPRApak L	340 liters (90 gal)	1.5 times filtration flow rate
