What is Reverse Osmosis?
RO is a kind of newly developed membrane separation technology in the 1960s. It is working on the principle that water pass through the RO membrane whose bore diameter is 1/10000um (1/60000 size of Escherichia coli, 1/3000 size of virus) from higher concentrated side to the lower one by pressurize. So that the industrial pollutants and impurities such as heavy metal ions, bacteria, viruses separated from the input water.
RO unit is the key part of the whole system as it determines the output water quality. It mainly consists of booster pumps, membrane shell, RO membrane, control circuit and so on. The salinity filtering ability of RO host can be above 99% if with reasonable design. So the design reasonability will directly determine the cost-effective and operating convenience of the system. And power-saving, operating pressure, transmission and desalination rate and saltness of output water of RO membrane should be taken into consideration when design.
