The preparation methods of laboratory water

1, distilled water, laboratory is the most commonly used one kind of pure water, although making machine is cheap, but extremely slow and fee of water and energy consumption, the application will gradually decrease. Distilled water to remove most of the water pollutant, but cannot remove volatile impurities, such as carbon dioxide, ammonia, silicon dioxide and some organic matter. Fresh distilled water is sterile, but after storage bacteria easy breeding; In addition, the storage container is very exquisite, if be inert substances, ion and container shape substances can cause secondary pollution to precipitation. 2, liquid detergent: application of anion and cation ion exchange resin to remove the water, is to use a traditional for a longer time for the pure technique, after processing can obtain a certain purity of ultrapure water, but there is still a soluble organic matter in water, can effect to reduce the pollution of ion exchange column, the liquid detergent is also easy to cause bacteria breeding. 3, the water seepage, the principle of its generation is under the action of pressure, water molecules become pure water by reverse osmosis membrane, the impurities in the water by reverse osmosis membrane intercept discharge. Anti permeation and overcome the many shortcomings of distilled water and liquid detergent, using reverse osmosis technology can effectively remove salt dissolved in water, colloid, bacteria, virus and bacterial endotoxin and most of the impurities such as organic matter. Reverse osmosis water treatment machine, liquid detergent production machine, washing powder production machine, laundry detergent washing powder production machine production factory house, the previous: liquid detergent handle making machine which of several systems
