GORE™ Membrane Filter Sock and Tube assemblies provide excellent filtration efficiency and economical performance in high flow rate and/or high feed solids applications due to a combination of GORE™ membrane's unique properties and extensive application and manufacturing expertise.
GORE membrane filter socks and GORE® filter tube assemblies are used in Kraft pulp mills, Chlor-Alkali plants and other process or wastewater filtration applications in chemical processing industries. GORE™ membrane filter socks have a unique microporous membrane surface that prevents particles from becoming imbedded inside the membrane structure. The membranes are available in several different micron ratings and are laminated to a polypropylene felt, a polyester felt, or a felt made with Gore fibers depending on the chemical and thermal requirements of the application.
Markets & Applications
Kraft Pulp Mills
GORE membrane filter socks are used in white liquor and lime mud wash tubular pressure filters in the pulp and paper industry.
The membranes, available in several different micron ratings, are laminated to a polypropylene felt support. An all welded construction and special EPDM O-rings are used to greatly reduce the potential for bypassing found in other sock constructions.
- Higher throughput
- Less frequent acid washings
- Better upset recoverability
- Longer effective life
Depending on your location, GORE membrane filter socks can be purchased directly, through licensed agents or OEM's. Please contact us for more information.
Chlor Alkalai Processing
GORE® Filter Tube Assemblies as well as our all ePTFE GORE® Membrane Filter Socks and our CPVC patented GORE® Filter Tube Support Elements are used to purify the brine regardless of the brine source in the Chlor-alkali process. This replaces the old three step filtration (clarifier, sand filter, precoat filter) with a one step filter using our filter products that do not require any precoat. There are over 100 installations worldwide successfully using this precoat-free technology.
