In the laboratory, water is the most used reagent. However, it is not respected and its purity is not being taken care of. This leads to a negative impact on laboratory experiments. The accuracy and precision of the experiments are getting lost due to impure water. For each type of experiment, there is a need for a certain purity or grade of water. Using tap water for all laboratory purposes kills the aim of getting good results. To obtain better purity in water, it is necessary to have a lab water purification system. Water purification system for laboratory helps in maintaining purity of water in the laboratory. The water purification system for the laboratory serves as a one-stop solution for getting the desired amount of quality and quantity of laboratory water at the desired level.
Tap water usually contains microorganisms, dissolved gases, ions, organic and inorganic compounds, and particles. Most of these contaminants will influence the results of the experiments. Hence, usage of tap water as such is impossible in the laboratory for sensitive experiments.
There are three types of water - Type 1 water, Type 2 water and Type 3 water.
Tuned to the laboratory's needs, it is necessary to design a water purification system for the laboratory. The purification process should be available in the minimum time in the lab water purification system. Demand for lab water systems has increased drastically over the years because parts-per-million was a lesser level of contamination. But nowadays, even parts per trillion have been seen as major contamination in water. A few years ago, only ionic contaminants were given importance. But these days, gases and organics are also carefully watched in water.
Eight methods are usually used to purify water. They are
Initially, tap water has to be converted into pure water. Then the water system should be converted into ultrapure water. Thus, extracting ultrapure water from tap water is a minimum two-step process, which demands much time, finance and energy. As the number of treatment steps increases, the loss of water also increases as in each step, some water is lost as an impurity. Additionally, there is a need for pre-treatment before the passed into major purification technology. Pre-treatment removes larger suspended molecules, which will block the filters in membrane filtration. Post-treatment chlorination is used for the prevention of bacterial growth during the storage of water in larger tanks. High pure water is reactive to minute molecules. Hence, the storage time of filtered water should be kept minimal.
The success of a laboratory depends on the reliability of pure water as it impacts the repeatability and accuracy of results. Desired purity of water is different for different methods and instruments. One should look carefully at the purity and conductivity of water needed for each experiment and accordingly, run the required combo of purification methods. It will help to optimize the expenditure needed for running the process. For quantity of water, quality can’t be traded off and vice-versa. One can’t use low grade water for sophisticated equipment. Also, it is not advisable to utilize pure water for washing the glassware initially. However, after the experiment, high pure water should be used for washing.
