In hard water areas, Scale and Scum come into your home because of the hardness minerals in your water supply. Scale coats the inside of your pipework with a hard, heatproof layer that makes your heating system burn more fuel, and Scum kills the bubbles in your bath and makes you use extra washing powder.

Hard Water

Hard water delivers lime-scale right at the heart of your plumbing system.
Scale blocks pipes, furs up boilers, affects the functioning of appliances.
Scum takes the bubble out of your bath water and leaves a sticky, dull residue on your hair, skin and clothes.
Rinsed crockery and glassware looks streaky, baths and sinks look smeary.
Towels and nappies may feel stiff and rough after washing.

Soft Water

Immediate savings on heating energy.
Cuts down on repair, replacement and maintenance of pipes and appliances.
Puts the sparkle back into baths, sinks, showers, crockery and glassware.
No more blocked shower heads, scum rings in the bath or furred kettles.
Acts as a natural conditioner on fibres as well as your own hair and skin.
Gives rich lather from very little soap and crystal clear water for rinsing.
Saves on washing machine and dishwasher chemicals.

How Water Softeners Work

In brief, water softeners are designed to remove calcium and magnesium (the cause of scale and scum) from hard water. They are intended to treat the whole house, so are installed where the water supply enters the premises.

Hard water pumped into your home passes through a bed of resin crystal beads in the unit which capture the lime scale and minerals by an ionising process. When the beads become exhausted, they need to be regenerated by flushing through a salt water solution.

Ion Exchange

Ion Exchange softening is the only water treatment that effectively removes hardness salts (Calcium and Magnesium). These salts are replaced by sodium, whose higher solubility avoids salts incrustation. Feed water passes through a resin bed inside the softener vessel. In this moment hardness salts are captured by the Ion Exchange beads. When resin is completely depleted it should be started a regeneration. Regenerations are commanded by the control valve.

Water softening happens through a process called ion exchange, which uses an ion exchange resin. The resin comprises of tiny polymeric beads which are specially formulated so that they can be charged with certain ions. Calcium and magnesium, the causes of scale and scum from hard water, are referred to as ions, and as water passes through the resin, the calcium and magnesium ions swap places with the sodium ions on the resin. Sodium salts, unlike calcium and magnesium, are highly soluble so sodium does not cause scale or scum. When all the sodium ions have been exchanged for calcium or magnesium, the resin must be regenerated by recharging it with sodium ions. This is done by flushing the resin with salt solution (brine).
