The role of Salt in Water Softeners
Water softeners contain a bed of ion-exchange resin. The minerals (principally calcium carbonate and magnesium carbonate from chalk and limestone areas of the country) which are the cause of so-called 'hard' or 'very hard' water (ie containing >200mg/l Calcium Carbonate equivalent) attach to this resin so that the water leaving the water softener ends up 'soft'. Soft water regions of the country have <100mg/l calcium carbonate equivalent so have less need for water softeners. Softened water saves money by reducing eg washing powder and shampoo consumption, and helps to prevent washing machines, dishwashers etc. becoming clogged up and thereby failing. Everyone in 'hard' and 'very hard' water areas, namely the counties of:
Hampshire (excluding Isle of Wight)
in the south of England should seriously consider having a water softener, if they haven't already got one, fitted as a matter of sound economics and to help the environment (less consumption of cleaning products saves energy from production through end-use and disposal / water treatment).
Water softeners are easy to run - all that is needed is to add salt which refreshes the ion exchange resin - essential to maintaining the output of soft water from the machine.
Type of Salt for Water Softeners
The most modern water softeners take salt replenishment to the next level. With these machines, all you have to do is slip two SALT BLOCKS into the machine. These avoid mess from possible spillage and their light weight (each block weighs just 4Kg) makes refilling your machine a really simple matter. We supply salt blocks for HARVEY'S water softeners in waterproof plastic packs for easy, safe storage and replenishment.
