Simplex and Duplex Water Softeners: What’s the Difference?
Simplex and duplex industrial water softeners work by ion exchange – but what’s the difference
between the two? Find out more here.
(firmenpresse) - The prolonged use of hard water in industrial processes has consequences that can cause
premature damage to expensive plants and equipment, due to limescale build-up. This is rather more
prevalent in the UK, where public water is not suitable for industrial processes due to high
levels of calcium and magnesium. An industrial water softener provides a good solution for
reducing calcium and magnesium ions for industrial use.
So why is there such a need to correct this hardness? The geographic formation of most areas in
the UK is made up of sedimentary rocks, such as limestone, chalk, sandstone, and flint. These
rocks have a high content of calcium and magnesium, and when rain falls on the rock surface,
the minerals dissolve and form hard water. Therefore, in the case of industrial use, it causes
limescale buildup that damages the equipment and reduces the efficiency of boilers, among other
things.
Industrial water softeners work by ion exchange processes to replace calcium and magnesium ions
with sodium ions in two different types of systems: simplex and duplex.
Simplex and Duplex water softeners
During the ion exchange process, hard water passes through a pressure vessel that contains resin
columns and resin beads charged with sodium ions. The sodium ions replace calcium and magnesium
ions to reduce the content of these minerals to the required levels. The unfiltered wastewater
(with a high content of calcium and magnesium) is flushed out into the drainage system. This is
how both the simplex and duplex systems work.
Over time, the resin beads become less efficient, requiring regeneration or rejuvenation. During
the regeneration cycle, the resin column is supplied with saltwater (brine) to remove the calcium
and magnesium ions, which are flushed out into the drainage system. The process takes about 60 to
120 minutes. During this time, there is a cut-off supply until regeneration stops.
Difference Between the Simplex and Duplex Industrial Water Softeners
There are distinct differences between the two systems, and they are as follows:
Resin Columns
The simplex type contains a single column responsible for the process of ion exchange, while the
duplex type has two columns to complete the same process.
Intermittent regeneration
When the simplex type softener undergoes regeneration, the supply of soft water stops because,
during this time, the vessels are not operational to clean and recharge the resins.
On the other hand, with the duplex type, when the resins are nearing exhaustion and need to
undergo regeneration, the second tank automatically picks up and continues feeding the industrial
processes. A continuous supply prevents any interruptions in the workflow.
Application
Because of the temporary cut-off supply of soft water, the simplex type is not suitable in
commercial settings where there is a 24/7 supply requirement. It can only be suitable where the
need is moderate, such as in light commercial applications or large residential buildings, for
instance.
The dual type, on the other hand, is suitable where a constant supply is a requirement.
Get Expert Advice on the Correct System
Soft water is a requirement in industrial settings to prolong the life of machinery and
equipment. It doesn’t contain high levels of calcium and sodium, two minerals that cause damage to
plants because of limescale buildup. Depending on the need for supply, you can choose between
simplex and dual industrial water softeners, however, it is important to consult an expert company
to recommend the type of system suitable for your needs.
