Deionized Water And Some Common Water Purification Processes

water deionization process You got the answer right!

These laboratories need different levels of water purity for the different levels of sensitivity of their analysis and experiments.


Water can be found in each laboratory type, be it medical, pharmaceutical, chemistry, and microbiological. The whole water purification process is long and involves many steps. Activated carbon -known as adsorption media and works effectively removing chlorine in water by a catalytic mechanism and dissolved organics by adsorption. Ultraviolet disinfection -It uses ultraviolet light which is a powerful sterilizing agent to kill bacteria and identical microorganisms. Ion exchange -This process removes various metals particularly heavy metals present in water however ion exchange will retain microorganisms. Ok, and now one of the most important parts. Reverse osmosis -Osmosis is the movement of water from higher concentration to lower concentration as caused by the osmotic pressure. As a result, So there’re still impurities found in distilled water similar to silica, ammonia, and identical organic compounds. Storage of distilled water is also important to keep it from contamination.

water deionization process Distillation -Water is heated and the condensed vapor is trapped and collected. In reverse osmosis, water is passed through a filter using a higher pressure than the osmotic pressure to separate the impurities. There are also different kinds of water types in accordance with their use in the laboratory. Type This is the ultrapure water which has very low levels of ions, organic molecules, bacteria, and particles. It is commonly manufactured by combining purification technologies like activated carbon, reverse osmosis, ion exchange resins, ultraviolet photooxidation, filtration processes, and electrodeionization. It is used for analytical methods like high pressure liquid chromatography, gas chromatography, and ‘inductivelycoupled’ plasma mass spectrometry. Seriously. Type This send water type is known as pure water and may contain a minute percentage of ions, organic molecules, and possibly a small quantity of microorganisms. Contrary to popular belief, tap water can’t be used for just about anything in the lab because of the impurities found in it. Now look. There are different kinds of water types corresponding to the different needs of a laboratory.
