Its working principle is to apply a certain pressure to water so that water molecules and ionic mineral elements pass through the reverse osmosis membrane, while most of the inorganic salts, organic matter, bacteria, viruses, etc. dissolved in the water cannot pass through the reverse osmosis membrane, thereby strictly separating the pure water that has permeated and the concentrated water that cannot permeate. When sampling, ultrapure water equipment often needs to sample ultrapure water of different water depths in layers to judge the water quality. Existing ultrapure water equipment does not have a sampling function and can only be sampled by manually opening the water storage tank.
