20" X 2.5” Lime, Scale & Iron

The ASC Anti-scale inhibitor cartridge is designed to replace most standard 20” water filter cartridges and has 5.7 lbs +/- of Polyphosphate in the refillable cartridge. The ASC polyphosphate refillable water filter cartridge inhibits the build-up of scale in a water system and can be installed on the incoming main, if required.
Limescale is caused by the presence of calcium and magnesium salts dissolved in water in the form of soluble bicarbonates. Through the effect of heat, these salts are transformed into insoluble carbonates and tend to agglomerate as crystals, forming a calcareous scale on the surface of pipes, coils, and storage tanks used for the production of hot water for domestic or industrial use.
Over time, the scale obstructs pipes and forms thick cement-like encrustations in heating systems. This leads to inefficiency and to a drastic reduction in energy output, as well as to high service and maintenance costs.
Polyphosphate treatment is widely used in hotels, coffee shops, and restaurants, and homes, is safe to drink, simple, effective, and economic solution for the problem of scale deposits.
When dissolved in water, the polyphosphate prevents the formation of calcium carbonate encrustation by acting upon its crystallization, affecting the hardness of the water.
Overtime, it will also break down existing deposits. Polyphosphates also provide effective protection against corrosion by creating a thin protective film on the surface of the pipes, coils, water heaters, Ice machines, pool equipment, solar hot water systems,  coffee equipment and steam ovens etc. The result and benefits will be:

Prevent "red" (from iron) and "black" (from manganese) water

Reduce soluble lead and copper in potable water

Clean or dissolve precipitated mineral scale already existent in water distribution lines

Prevent and/or retard scale formation (from minerals depositing) and corrosion (from low pH and/or dissimilar metals) in the water distribution system

Poly Phosphate
water conditioning can eliminate the use of an ion exchange water softener in many cases, and is usually more economical and environmentally friendly, not needing to regenerate, wasted water and salt purchases.
