Applications:

- Commercial Use: Effectively reduces scale by separating hardness so they cannot precipitate and form deposits when heated. These cartridges are used with many commercial-grade coffee and tea brewing machines, ice makers, beverage dispensing equipment, and water misters.

- Residential Use: As part of a water treatment system, phosphate cartridges are used to maintain distribution systems. The corrosive properties of water can be attributed to low pH; high temperature and total dissolved solids. Phosphates are used in water treatment to sequester inorganic contaminants (iron, manganese, calcium, etc) and to maintain water quality.

- Pre-Treatment To Reverse Osmosis (RO): Provides protection by removing contaminants such as chlorine, and organic, and binds hardness that can foul RO membranes, thus reducing the efficiency of the membrane.
