Principle and characteristics of laboratory ultrapure water machine

Release date: November 26, 2019 23:36:39

Common methods of preparing laboratory water

one , distilled water:

The most commonly used pure water in laboratory, although the equipment is cheap, it is extremely energy consuming and water consuming, and the speed is slow, so the application will be gradually reduced. Distilled water can remove most of the pollutants in tap water, but volatile impurities such as carbon dioxide, ammonia, silica and some organic compounds cannot be removed. Fresh distilled water is sterile, but it is easy for bacteria to reproduce after storage. In addition, the storage containers are also very particular. If the non inert substances are not used, ions and molding materials in the container will be separated out, causing secondary pollution.

two Deionized water:

The application of ion exchange resin to remove anions and cations in water is a traditional process used to prepare pure water for a long time. After treatment, ultrapure water with a certain purity can be obtained. However, there are still soluble organic matters in the water, which can pollute the ion exchange column and reduce its efficiency. The storage of deionized water can easily cause bacterial reproduction.

three Reverse osmosis water:
         The principle of its formation is that under the action of pressure, water molecules become pure water through the reverse osmosis membrane, and the impurities in the water are intercepted and discharged by the reverse osmosis membrane. It overcomes the disadvantages of bacteria, bacteria and water reverse osmosis technology.

Our company produces the laboratory ultra pure water equipment characteristic

The characteristics of laboratory water use is that the water consumption is not large, but the water quality is high. In view of this actual situation, our company has developed ultra pure aquatic products which are particularly suitable for laboratory use, and its process is reverse osmosis Add ultra pure water column Mixed bed equipment, or reverse osmosis plus EDI The electrodeionization equipment has the following remarkable characteristics:

It's automatic with water. When the storage tank is full of water, the equipment stops automatically.
   One machine can be used for both purposes. Pure water and ultra pure water are produced and on-line electricity is used guide It is convenient to use.
   have RO Automatic membrane flushing function, extended RO The use time of membrane.
   It is convenient to upgrade and strengthen the pretreatment system for the water source with more impurities.
   The whole machine has beautiful appearance, reasonable design and layout, and convenient maintenance and replacement of consumables.
   Automatic operation, with tap water shortage protection, system high-pressure protection and stop immediately.
