Reverse osmosis equipment is a kind of equipment used to prepare pure water. Raw water (tap water, groundwater, etc.). ) filtered by reverse osmosis membrane twice, reaching the standard of direct drinking water. The filtration accuracy of reverse osmosis membrane is 0.000 1 micron, which can effectively remove colloid, bacteria and heavy metals in water.
In the production process of reverse osmosis equipment, whether the effluent is qualified is generally expressed by conductivity. Conductivity is not an instrument to measure the purity of water, but mainly to measure the ion content in water filtered by reverse osmosis membrane. The less the content, the less ions in the filtered water. Relatively speaking, the higher purity.
Reverse osmosis equipment can be divided into primary reverse osmosis (single-stage reverse osmosis) and secondary reverse osmosis equipment (double-stage reverse osmosis equipment) according to different manufacturing processes.
The difference between the two is relatively simple. The equipment filtered once by reverse osmosis membrane is called primary reverse osmosis, and the water treated twice by reverse osmosis membrane is called secondary reverse osmosis equipment.
Generally, the conductivity of primary reverse osmosis equipment is about 30, and that of secondary reverse osmosis equipment is below 10.
Another difference between the two is that the technological process and equipment accessories of manufacturing equipment are different.
