The ability to remove many dissolved substances efficiently, yet produce good tasting finished water.
RO does not add any other chemical to your water. It merely separates the dissolved substances from the incoming water.
RO performs a separation without a phase change. Thus, the energy requirements are low.
RO systems are compact, and space requirements are less than with other desalting systems, e.g. distillation.
RO equipment is standardized-pumps, motors, valves, flowmeters, pressure gauges etc. thus,the learning curve for unskilled labour is short.
Many RO systems are fully automated and designed to start-up and shutdown automatically through interlocks. Thus, RO plants usually require little labour.
Due to their modular design, maintenance is easy. Scheduled maintenance can be performed without shutting down the entire plant.
The modular design also makes expansion an easy option.
