The best way to explain Temporary treatment is to think of a snowflake.
Underneath a very powerful microscope, a snowflake is a very beautiful shape with sharp edges that enables it to cling to things, such as branches of a tree.
Dissolved limestone calcium (chalk) is very similar. In a glass of water we cannot see the calcium as it is clear, however we can sometimes feel the chalk on our tongue. To make it visible to us, we can add a chemical to the water, giving us this result:
The Temporary treatment of hard water through scale reducers includes either chemical treatment or physical treatment.
There are various forms of temporary water treatment. These include:-
(Polyphosphate crystals or Siliphos balls):
Chemical treatment systems work by coating the pipework with a fine residue of chemical which resists the sticking of the dissolved calcium to the pipework leading to central heating boilers or electric showers.
The chemical is of a food grade quality, and the cartridges need to be replaced or topped up approximately every 6 months.
(Magnetic, Electric and Electrolytic):
Magnetic scale reducers should work by ‘hitting’ the calcium ‘snowflake’ with a force powerful enough to cause it to roll up from an irregular shape (like a snowflake), to a regular shape (like a football) allowing it to pass freely through the water.
There is, however, no scientific evidence that magnetic scale reducers work all of the time, and as a result they are often unpopular and can be purchased very cheaply. There is evidence however that electrolytic reducers work best of all scale reducers.
Once the calcium ‘snowflake’ has travelled far enough into the property and can no longer feel the effect of the physical scale reducer, it will open back up and return to its original sharp edged state, sticking once again to pipework, kettles and showers.
For this reason, this type of scale reducer should ideally be fitted immediately before the combination boiler, electric shower and hot water cylinder where it can work most effectively.
