Definitions

  • the invention relates to water softening systems, and particularly to water softening systems using electrical water softening devices.
  • Limescale causes furring in many household appliances, such as kettles and showerheads. Scale also appears for example in baths, basins and toilets. Shampoos and detergents do not lather as they should and instead produce scum. These are the visual symptoms, but there are many hidden ones. Particular damage is caused to pipes and water heaters by internal limescale encrustation, which often results in a substantial waste of energy. For example, just 3mm of scale can cause up to 25% loss in heating efficiency. Eventually it is necessary to replace items such as pipes and hot water cylinders. However, at the same time, the minerals present in hard water are essential to humans and animals. Studies have shown that high levels of calcium in drinking water can reduce the incidence of heart attacks, compared to the incidence of heart attacks in areas having softer drinking water.
  • aerials ie. conducting wires
  • electronic watersoftening units are controlled by pre-programmed microchips to provide the aerials with electrical signals having a combination of different frequencies and amplitudes.
  • the electromagnetic radiation given off by such aerials interacts with the dissolved salts present in hard water, causing the formation of sub- microscopic clusters.
  • These clusters act as nucleation seeds for the precipitation of calcium carbonate when the water is heated. Precipitation, in the form of larger crystals, occurs on these seeds in the body of the water and not as a hard deposit of limescale on the inside of the pipes.
  • the treated water which contains less dissolved free calcium appears to behave much like chemically softened water. There is reduced encrustation, better lathering and less scum formation in the hot water. At the same time, but unlike chemically softened water where all the minerals are removed, the cold water from the tap can be safely used for drinking. There is no need for a separate "hard water tap" and no health risks whatsoever.
  • a typical test for hard water is to measure the amount of lather created by soap.
  • the poor lathering of soap associated with hard water is caused by the reaction of the soap's soluble compounds with dissolved free calcium.
  • the clusters created by an electronic water-conditioning unit convert more of the dissolved free calcium in the water into crystals in suspension than would otherwise occur.
  • the resulting water, with less dissolved free calcium now behaves as if it were chemically softened. Soap will create more lather despite the fact that the total amount of calcium, dissolved and suspended, remains the same.
  • the treated water is safe to drink. There is no need for a separate drinking source, no health risks and no salt effluent.
  • the method preferably includes raising the iron concentration of the water to at least about 70ppb (parts per billion) (or 70 micrograms per litre).
  • the method may further include the step of measuring the rate of flow of the water.
  • the method preferably includes controlling the rate at which the iron concentration is increased in accordance with the measured rate of flow of the water.
  • the invention also provides a water softening system for carrying out the above method, the system comprising a magnetic or alternating current electrical water softening device attached to a water supply at a first location, and dosing means attached to said water supply at a second location upstream of said first location for increasing the concentration of iron in the water reaching said water softening device.
  • said first and second locations may both lie within said house or building.
  • the dosing means may be a dosing pump or an electrolytic device.
  • the water softening device may be an electronic water softening unit provided with at least one aerial for producing electromagnetic radiation within the water supply.
  • Said water supply may be provided in a pipe, in which case the water softening device and dosing means may be connected or attached to said pipe.
  • the dosing means may be adapted to add a soluble iron salt, such as ferric chloride or ferric sulphate, to said water supply.
  • the water softening system may further comprise flow rate detection means for measuring the rate of flow of water in said water supply.
  • the dosing means may be adapted to add iron to said water supply in quantities which vary according to the measured rate of flow.
  • the water softening system 2 shown in the Figure comprises an electronic water softening unit 4 (for example Water King (RTM) WK1 available from the applicant, Lifescience Products Ltd) attached to a water pipe 8.
  • the pipe 8 directs water from a water supply 10 to a water user 12.
  • the electronic water softening unit 4 is provided- with two aerials 14, each of which is coiled around the pipe 8.
  • the aerials 14 are fed by an alternating electrical supply (not shown separately) provided by said electronic water softening unit 4, in order to radiate electromagnetic radiation into the water within the pipe 8, and thus soften the water in known fashion.
  • a magnetic water softening unit can be used as an alternative to the electronic water softening unit 4.
  • the dosing pump 6 is located upstream of said electronic water softening unit 4, and feeds one or more soluble iron salts (such as ferric chloride, or ferric sulphate) into the water within the pipe 8.
  • An electrolytic device shown schematically as 18 may be provided as an alternative to the dosing pump 6, and may use a sacrificial anode (not shown) to increase the iron concentration of the water.
  • the system 2 also comprises a flow rate detector 16 which measures the rate of flow of the water. This detector feeds signals to the dosing pump 6 so that the rate at which the water is dosed is increased if the flow rate increases.
