Seitz® HS Series Depth Filter Sheets

Filter sheets for craft breweries  

The Seitz HS Series Depth Filter Sheets were developed to meet the production needs for various products including beer, gelatin, sweeteners and craft brewing industries, especially those with complex conditions and high filtration temperature.  The high stability enables long production runs of aqueous and higher viscosity fluids at low and high temperatures. Available in multiple grades, the homogenous and consistent media is suitable for microbial reduction and applications requiring fine, clarifying, and coarse filtration. Get the quality your business deserves with the Seitz HS series of depth filter sheets and enjoy: 

  • Reliable microbial reduction with tighter grades
  • Media stability due to high wet strength; easy to remove after use, especially with sticky fluids
  • High economic efficiency due to a long service life  
  • High solids retention, very good permeability, excellent filtrate quality
  • Each individual filter sheet is laser etched with the sheet grade, batch number and production date for full traceability.

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).



Seitz HS 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.


  1. Rinse with warm water 60 °C (140 °F) for 15 minutes
  2. 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).


3When rinsing in the reverse flow direction, it is critical to control particulate and microbial levels in the rinse water so that the sheet's filtrate side is not contaminated. Water used for reverse flow flushes should be particle-free, and if the filter will not be sterilized prior to re-use the water should be free of microbes. Backwashing should be in a diagonal direction from outlet to inlet in a plate and frame filter.
