Softening Processes in Swimming Pool Technology

Natural water released from the soil contains, in addition to other elements, Calcium and Magnesium salts.  The sum of both substances gives the total hardness. Changes in the pH value or temperature can cause precipitations. These visible precipitations (lime) can deposit on piping, basin walls, chillers, attraction walls, fountains and steam raising units. These deposits may cause local mechanical or thermal charges that may, sooner or later, result in breakdowns of plant components!

These precipitations can be avoided with a water softener, type DOUCEMAT by ProMinent, that works with the ion exchange principle and ensures supply with soft water. The ion exchange principle is achieved with the use of exchanger resin. This resin detracts Calcium and Magnesium ions from the water and substitutes Sodium ions. After depletion of the resin, it is re-activated with a salt spring regeneration (time or quantity-dependent). This procedure can be repeated as frequently as required.

As a result, the operation time of the steam raising unit, the use of the swimming pools or the optic impression of an attraction remain unclouded! The softening device by ProMinent is just one of many different components in the complex system of water treatment.
