Reverse Osmosis

Some applications (e.g. laboratories) have a need for the purest form of water. Calmag supply a range of commercial Reverse Osmosis plants designed to meet these needs. Reverse Osmosis is the most effective form of filtration. Our units work by passing water through a series of filters, and special semi-permeable membranes. As the water passes through each of the stages, different levels of contaminants are reduced to a level of upto 98%.

We have two models of Reverse Osmosis plants available, Compact Model and Pro Model.

Additional Information

C8000 RO Plant is 3 phase form as standard not single phase.
The flow rates quoted are anticipated output after 3 years of operation. Initial output is likely to be higher than quoted.
All plant performance is rated at UK mains water temp of 12°C.
RO Plant requires softened and dechlorinated water. A Duplex softener is recommended for continuous plant operation.
As RO Plants are sophisticated pieces of equipment, they must be serviced at intervals of no more than 6 months, or more frequently if site conditions demand. Failure to do so may invalidate the warranty.
