Cartridge Water Filter
Cartridge filtration units generally operate most
effectively and economically on applications having
contamination levels of less than 50 – 80 ppm. For heavier
contamination applications, cartridges are normally used as
final polishing filters. In the following the basic systems
of cartridge filters are listed
Wound Cartridge Filters :
- the most common type of depth filters
- materials: natural or synthetic yards, which are wounded
around a central tube or former
- numerous applications in the industry
Bonded Cartridge Filters :
- one-piece cordless construction, consisting of resin bonded fibers of solid
particles
- their filtration range is between 5 to 125 micron, good chemical
compatibility/flow rate
- frequent application: viscous fluids, process duties
Pleated Cartridge Filters :
- today's most common cartridge filter system
- materials: cellulose basis, resin impregnation; polyester, micro fiber
glass, polypropylene
- advantages: increased surface area (up to 60 %) compared to traditional
cartridge filters
Metal Fiber Cartridge filters :
- material: stainless steel fibers, connected to a mat
- used in the polymer industry
Hollow Fiber Membrane Cartridge Filters:
- for applications under 0.5 micron, for example used for the removal of
aerosols. Further applications can be, for example microbiology (filtration
range down to 0.01 micron), where sterility is very important
- materials: hydrophilic polyamide/polypropylene
