The need to reduce the hardness of water is the most common form of water treatment. Hard water is created when naturally soft rain water percolates through subterranean rock strata and dissolves many solids including, in particular, calcium and magnesium. There are many areas therefore, where the supply water contains a significant level of these salts. It is called ‘hard water’ because of the water hard deposits created when this type of water is used in many applications.
The deposits are often called scale. However, it is actually more like concrete, forming a thick coating on heat exchanging elements and the inside of boilers, tanks and pipes. In addition, the hard minerals left in solution significantly detract from the performance of soaps and detergents which then have to be used in greater quantities to achieve the necessary cleaning performance. This not only adds to the level of deposits occurring inside systems and equipment, it also adds significantly to the chemical waste discharged into our sewer systems.
The other main problem created by scale build up is the reduction in efficiency of all heat exchange systems due to the insulating effect of the deposit. This will increase the energy costs and, in addition, can create overheating.
A cost effective way solve these problems is to remove the dissolved hard mineral salts from the water, replacing or exchanging them with ‘soft salts’ which are more soluble and therefore do not form hard scale. This is achieved by using one of our wide range of fully automatic water softeners.
They work by a process known as ion exchange. The hard water passes through a high quality exchange resin column inside a pressure vessel. The resin removes the calcium and magnesium ions from the solution and exchanges them for sodium ions. When the resin is about to become exhausted the softener commences the regeneration phase which is initiated by timer or volume control. The actual regeneration is achieved when the softener draws a solution of common salt – called brine – through the column if resin which displaces the captured calcium and magnesium ions and replaces them with the sodium ions in the brine. Throughout the subsequent rinsing is flushed to drain and does not enter the service line. The regeneration period takes between 60 and 120 minutes, depending upon the size of the softener, and it can be repeated as often as necessary over many years without significant loss of performance.
Simplex water softeners, or single column water softener, are best suited to steady demand applications up to m
Duplex softeners function similarly to simplex units, except that they consist of two resin columns where one is
