Description

Technical Field

[0001] The utility model relates to the technical field of pure water equipment, in particular to pure water equipment for laboratories. Background Art

[0002] Pure water equipment primarily utilizes reverse osmosis membrane technology. Its working principle is to apply a certain pressure to water, forcing water molecules and ionized mineral elements to pass through the reverse osmosis membrane. However, most inorganic salts, organic matter, bacteria, and viruses dissolved in the water cannot penetrate the membrane, thus strictly separating the permeated pure water from the impermeable concentrated water. Traditional laboratory pure water equipment still has various problems and is difficult to meet practical application needs.

[0003] However, the existing pure water equipment is not effective in removing other impurities contained in the water, resulting in poor quality of the produced pure water. The existing pure water treatment equipment also uses activated carbon to adsorb suspended matter, colloids and other impurities, but the adsorption effect of activated carbon decreases significantly with the use time, and manual replacement of activated carbon takes a long time, which affects the use of pure water treatment equipment and has certain inconveniences. Simple activated carbon filtration cannot meet the requirements of laboratory pure water. For this reason, we propose a laboratory pure water equipment. Utility Model Content
