AQUA offers various polyphosphate cartridges that defer in sizes and with defined characteristics.

Polyphosphate salts are anti-scaling chemical agents. Therefore ideal for use with hard calcareous water, and where eliminating of scale and corrosion is required.

A polyphosphate cartridge consists of a plastic canister filled with crystal salts of different mesh. The canisters can vary in size. Once the polyphosphate salt has dissolved a chemical reaction takes place withholding the suspended particles. This prevents scaling and depositing of the particles along pipelines or inside mechanical components, avoiding inefficiency.

To be efficient, all polyphosphate cartridge require a determined time of water contact. However, thanks to its fast dissolving effect this period is relatively short.

Polyphosphate cartridges have a low pressure drop. Usually they are used in industrial applications. Standard regulations require that only minimal dosage is allowed when applied to drinking water. Therefore, in these cases, it is necessary to have an accurate and controlled dosage guaranteed by a dosing pump (see our Dosing Systems Product Guide).

It is important to fully understand the use of such cartridges so as to determine the correct application. For applications and maintenance, please refer to the data sheet indicated for each model.
