Simplex
or single column water softeners are best suited to consistent demand applications of moderate total water comsumption. Regeneration is controlled by the multiport valve head assembly. Time clock and delayed regeneration meter controlled softeners are normally programmed to regenerate at 2.00am, or at a convenient period of low water use. 'Immediate regeneration' meter controlled softeners regenerate the resin column as soon as the water meter runs out.
During regeneration the single column control valves will bypass hard water to service unless a bypass closedown facility is specified. Generally, simplex softeners will need to be sized to give at least
one day's softened water 
output before regeneration.
Duplex
Softeners give a continuous supply of softened water. Duplex systems use two resin columns, one in service, the second on standby. The water flow to service is metered and when the service column is exhausted, the control valve automatically switches, putting the second unit online. The exhausted resin in the first column is then regenerated and remains on standby until the second system is exhausted, the the valve switches back to the first column again.
Duplex softeners are normally sized to give one regeneration per column per day, but each column can be generated more frequently if required. Parallel run systems with both vessels on line at the same time are available.
Reverse Osmosis
Is a process that is used to remove a wide range of salts to give water of a high purity - Osmosis is a natural process involving fluid flow across a semi-permeable membrane barrier. It is the process by which nutrients feed the cells in our bodies and how water gets to the leaves at the top of trees.
Reverse Osmosis is therefore considered a much safer route of producing pure water for many commercial and industrial applications, and additionally the plant does not need to be taken out of service for the regeneration as a Demin plant does.
The size of the RO and choice of membrane will be determined by the permeate quantity required, feed water salinity and permeate quality expected. Low energy membranes allow the units to run at pressures around 150-200psi, and as such the pressure booster pumps required to generate the pure water are smaller, and the power consumption is reduced significantly.
