The B-series is the simplest of our reverse osmosis systems and unlike the C-series it doesnt have flow gauges, pressure gauges and a TDS meter. It is however built to the same high standards on a 304 stainless steel skid and using a high quality pump and membranes.
The B series RO systems recovery rate is 75%. All B-series ROs have an intergrated carbon filter to remove chlorine to prevent membrane damage.Pre-treatment:
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 B-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.
