Reverse osmosis equipment can be divided into primary reverse osmosis and secondary reverse osmosis, the following details the difference between the two:
Reverse osmosis equipment is a device used to produce pure water, reverse osmosis membrane will be the raw water (tap water, groundwater, etc.) for the second filtration to achieve the standard of drinking water, the reverse osmosis membrane filtration precision in the The filtration precision of reverse osmosis membrane is 0.0001 micron, which can effectively remove colloids, bacteria and heavy metals in water.
In the reverse osmosis equipment production process, whether the water is qualified, generally through the conductivity to show. Conductivity is not the instrument to measure the purity of water, it is mainly measured through the reverse osmosis membrane filtration of water ion content, the lower the content of ions in the filtered water, the less ions. Relatively speaking, the higher the purity.
Reverse osmosis equipment according to the different production processes are divided into a reverse osmosis (single-stage reverse osmosis) and two reverse osmosis equipment (two-stage reverse osmosis equipment).
The difference between the two is relatively simple, through a reverse osmosis membrane filtration equipment is called a reverse osmosis, water through two reverse osmosis membrane treatment is the secondary reverse osmosis equipment.
Generally a reverse osmosis equipment conductivity is generally around 30, the conductivity of the second reverse osmosis equipment in the following 10.
The other difference between the two is that the production equipment is the process and equipment accessories are different.
