Water Softeners

We install, service and supply water softeners.

water softenersIn the UK the formation of scale in water systems costs the industry approximately 1 billion per year. Scale will shorten the life of boilers, pumps, shower heads, washing machines and any appliance that comes into contact with calcium and magnesium irons and heat.

The water softening process removes the hardness minerals that cause hard scale by a process called Ion exchange. It removes the hardness minerals and replaces it with Sodium.

2.72 Light scale formation on the inner surfaces of pipes can be protective against the leaching of metals such as lead or copper, but heavier deposits are likely in hard water areas. These deposits increase the surface area and therefore the potential for microbial colonisation (biofilm formation) and can provide protection from the effects of biocides. In hard water areas, softening of the cold water supply to the hot water distribution system should be considered. This is to reduce the risk of scale being deposited at the base of the calorifier and heating coils, especially at temperatures greater than 60 °C, and the potential for scale build-up within the system pipework and components (eg TMVs) which may significantly reduce flow and adversely affect the efficiency of the system.

2.73 System materials need to be of a type that are resistant to corrosion (eg copper, stainless steel) as very soft water, natural or artificially softened, may lead to increased corrosion of the system pipework and materials. Where water softening systems are used, these should be fitted before any biocide treatment application. Suitable sample points should be fitted before and after the softener to allow for the operational testing of hardness and microbiological sampling if contamination is suspected.

Water softeners are available in simplex and duplex configurations and sizing is determined by a number of factors including water hardness, flow rate, pipe size, daily water consumption, pressure and applications.

Why we install water softeners-

A water softener is a unit that is used to soften water by removing the minerals that cause the water to be hard. When water contains a high level of calcium and magnesium it is called hard water. Hard water constitutes several problems throughout your industries.

Hard water is known to clog pipes, harbour bacteria and have severe cost implications where there are heat transfers i.e. hot water calorifiers. Hard water will creates a scale build up inside your pipes and water appliances reducing the efficiency of your water heater. This means more energy is used to heat water which will result in increased energy expenses.

How a water softener works –

The ion exchange process of softening water is basically the same for all water softeners. Hard water contains calcium and magnesium ions. Water softeners use resin beads, which hold sodium ions. When hard water passes through the resin beads inside the softener, the beads attract and hold the calcium and magnesium ions and give off the sodium ions. After this ion exchange process, the water leaving the softener is soft. Once the resin bed is loaded with calcium and magnesium ions, it must be cleansed (or regenerated) so that it can continue to soften water. Salt water is used to wash the resin beads. The brine solution loosens the hardness ions, which have built up on the resin beads; then the system backwashes and flushes the hardness minerals away. Once again, the resin beads hold sodium ions, and the system is ready to soften more water.

Why you should service your water softener –

Your water softener contains many moving parts that will wear with time.  It is important to replace certain parts of the water softener on a regular basis to ensure that slippage does not occur and the plant continues to protect your assets.

  • Our routine service will include:
  • A full strip down of each valve to check pistons seals and spacers are not worn.
  • Service checks to brine assembly and injectors.
  • Service checks to all operational valves associated with the water softener operation.
  • Full regeneration of each unit and checks to all stages of regeneration to ensure correct operation.
  • Service checks to brine well and system to ensure correct operation,
  • Resin bed clean.
  • Service checks to the controller to ensure correct operational sequences.
  • Service checks to all softener calculations to ensure correct flow rates and regeneration times.
  • Full report all findings and any recommendations for improvements.
