The C-series features a controller on the RO system that constantly monitors the quality of the permeate water and is also linked with safety controls on the system, to ensure the unit cuts out on low & high pressure, high & low conductivity, and full permeate tank signal. It will also run various pre and post flush cycles to maximise the life of the membranes.
The constant monitoring is automatic and the programming is all pre-set to ensure protection of the system at all times and to maximise the quality of the pure water.
The C series RO systems recovery rate is 75%. All C-series ROs have an intergrated carbon filter to remove chlorine to prevent membrane damage.Features:

RO plants must be supplied with softened and de-chlorinated water. A duplex softener is recommended for continuous operation. Utilising softened water for the feed to the RO will reduce the scaling potential on the membrane and therefore lengthen its working life. De-chlorination of the feed will reduce oxidation damage to the surface of the membrane. Membranes can also be fouled by Iron, Manganese, organics and microorganisms. For boreholes and other private supplies a full water analysis is advised before installing an RO so that a pre-treatment system can be specified.Site Requirements
The site requirements of an RO on site are vital for its sucessful operation. Apart from the RO requiring a certain quality of water, free from potential foulants, the system must be fed with sufficient volume and pressure. The flush phase of an RO requires more water than during normal service. The flush phase flow rates can be found in more information.
The site should also have sufficient space to allow siting, installation and ongoing maintainance.
The diagram above shows a typical plumbing layout involving a reverse osmosis system. The softenened water is fed to a Carbon cartridge filter on the inlet to the C-series RO. Water is then forced at high pressure through the membranes and the resulting permeate can then be collected in the permeate storage tank. Level probes (which are included in the RO system) control the operation of the RO. A delivery pump (suitable for use with RO water) may be used to boost the treated water to service.
