Which Scaltrol hard water treatment system is right for you?
- Choose the SC-50 or the SC-100, depending on your average water usage.
- For the typical household that uses 50,000 gallons of water per year, the SC-50 is the right choice. (Buying the SC-100 is more economical and reduces the frequency of replacing the cartridge).
- If your water consumption is higher, choose the SC-100.
- Both units provide hard water solutions for your whole house. They are easily fitted to your cold-water lines to protect against mineral scale and staining.
Controlling Hard Water Scale
Scaltrol’s water scale solutions were designed to control mineral scale from water sources that cause corrosion and decrease the efficiency of your appliances and plumbing.
Without a preventative scale control solution, your appliances eventually become clogged with scale buildup – sometimes past the point of fixing.
Since most water sources are saturated with large amounts of minerals, including calcium carbonate (lime scale), calcium sulfate, iron, and manganese, the Scaltrol units are installed at the water supply.
The concentration of minerals depends on your environment, based on rock formation, pH level, oxygen content, and temperature. Any increase or decrease in temperature can cause minerals to precipitate (i.e., form scale).
Preventing scale formation
To counteract mineral build-up, Scaltrol scale control units dispense a measured amount of polyphosphate which deposits a microscopic film to all surfaces.
The mineral molecules, which have a positive charge, are then attracted to – and held in suspension by – the negative charge of the polyphosphate, which acts as a sequestrant. Since the mineral molecules are no longer able to bind together, scale cannot form.
