The Fleck 2900 and 3900 Duplex commercial water softeners above, is one of the most popular commercial water softening systems used in the industrial water treatment industry.
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 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 exchange elements and the insides 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 on the surfaces of the heat source, thereby causing premature failure.
A cost effective way to solve these problems is to remove the dissolved hard mineral salts from the water and exchanging them with “soft salts” which are more soluble at high temperatures and therefore do not form hard scale. This is achieved by using one of our wide range of fully automatic commercial water softeners. They work by a process know 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 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 water (brine) through the column of resin which displaces the captured Calcium and Magnesium ions and replaces them with the Sodium ions in the brine. Throughout the regeneration period, the unwanted ions and the subsequent rinse water 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 commercial water softeners and can be repeated as necessary over many years without significant loss of performance.
Siata water treatment valves and programmers
Siata valve are used on commercial water softeners, demineralization systems, filtration systems. The valve can be used as top mounted on the water softener vessels, or side mounted. The microprocessor can be mounted on top of the valve, or remotely.
