FCCST20BB Aquafilter BIG BLUE 20 softening cartridge

Softening cartridge for Big Blue 20 housings – effective protection against scale

Aquafilter FCCST20BB has been designed for use in 20" Big Blue housings. Its function is to soften water through ion exchange, meaning the removal of calcium and magnesium ions responsible for hardness and replacing them with harmless sodium ions.

In practice, this means a lower risk of limescale deposits forming in plumbing systems, household appliances, heating components, and selected industrial applications. Reducing scale translates into easier equipment operation and better protection of components that are in constant contact with water.

How does Aquafilter FCCST20BB work?

The cartridge is filled with fine-grained ion-exchange resin with a high capacity for exchanging calcium and magnesium ions for sodium ions. This design is responsible for the proper water softening process and allows the effects of high hardness to be effectively reduced.

The FCCST20BB model has been designed so that water enters at one end of the cartridge and exits at the other, passing through the entire ion-exchange resin bed. This ensures that all filtration material works effectively and that contact between water and the media is maximized.

The cartridge also features its own final filter, which prevents resin particles from escaping beyond the filter. This is an important design solution that increases the operational safety of the entire filtration system.

Key advantages of the cartridge

• the cartridge contains technologically treated ion-exchange resin with grain sizes from 0.2 to 0.7 mm
• it is characterized by exceptionally effective exchange of calcium and magnesium ions for sodium ions, softening the water
• used for cold and hot utility water
• prevents scale buildup in household appliances and industrial machines
• the cartridge components have been approved by NSF and FDA
• the cartridge has a PZH hygienic certificate
• designed so that the water flowing through the cartridge penetrates the entire ion-exchange resin bed, ensuring its maximum performance

Application

The Aquafilter FCCST20BB softening cartridge is recommended wherever the goal is to protect systems and equipment against scale buildup. It works well as part of utility water preparation systems in homes, service points, and selected technical applications.

It can be used to protect:

• household appliances,
• heating equipment,
• plumbing systems,
• industrial machines exposed to deposits of calcium and magnesium compounds.

Operation and installation recommendations

Proper configuration of the filtration system has a major impact on the effectiveness and service life of the cartridge. To extend its operating life, a housing with a mechanical cartridge from the FCPS or FCPP series should be installed before the housing with the carbon cartridge.

In practice, preliminary mechanical filtration helps limit the passage of solid contaminants to the subsequent stages of the water filtration system. This is a beneficial solution both for the cartridge itself and for the entire water treatment installation.

Why choose the Big Blue 20 ion-exchange cartridge?

The large Big Blue 20 format makes the cartridge well suited to installations requiring efficient water treatment. The use of ion-exchange media makes it possible to effectively combat hard water problems, which often manifest as deposits on fixtures, reduced performance of heating equipment, and faster wear of components that come into contact with water.

Aquafilter FCCST20BB can serve as a standalone element for installation protection or as part of an expanded water filtration system. Solutions of this type are often combined with other treatment methods, and in more advanced setups they can also complement technologies such as an osmotic filter, reverse osmosis filter, reverse osmosis, or a complete reverse osmosis system.
