Does a water softener remove fluoride?

Fluoride levels are not affected when you soften water. A Harvey Water Softener™ only exchanges positively charged ions such as calcium, potassium, sodium and magnesium. Fluoride, chloride, sulphate and nitrate are negatively charged so won’t be removed during the softening process. Reverse osmosis units remove fluoride: If your natural water supply has excessive fluoride, we

How can I find out how much sodium will be in my water when softened?

The simplest route is to call the customer services number for your water supplier. Ask for the sodium level in the water supply and calcium carbonate hardness. (N.B. both sodium and calcium carbonate hardness must be expressed in mg/l. Divide the calcium carbonate hardness level by 2.175 and add the sodium in the water supply).

Why is hardness expressed as different measures?

When hardness is expressed as ‘mg/l as CaCO3’, it’s calculated as if all the calcium and magnesium were present only as calcium carbonate. Hard water is a mixture of calcium and magnesium, together with bicarbonate, sulphate, chloride, etc. Ca – is calcium, C carbon and O oxygen. CO3 means 3 atoms of oxygen are combined

Why don’t water companies soften the water?

Some water companies do soften their water, however, it’s not cost-effective to treat all water supplies. In 1947, the Government published a study which concluded that it was economically beneficial to soften water at the point of use, but uneconomical to treat all water centrally. This sparked the beginning of water softening for private use

Does the water hardness change?

The water quality varies from season to season as a result of rainfall and the source of the water prior to treatment. As the aquifers fill and empty, the amount of calcium and magnesium held in solution will vary. The speed of the water percolating from the surface will affect the hardness and this can

Is my water already softened?

In most cases, no. The only supplier that softens water to some degree is SES Water. The water is purified before it is safe to drink and the quality is improved through a process it calls ‘softening’. Its water treatment process moves the water to the softening tank, here lime is added. The lime reacts
