The importance of having quality water in laboratories, focuses on the usefulness and need that purified water represents to wash the glass material, in addition to feeding systems that produce ultrapure water; obtaining quality water is the main concern of laboratory users to carry out accurate experiments and optimal and efficient research; so water purification systems play a very important role; and we must be aware of the variety of systems that exist, their advantages and disadvantages.
In water purification systems it does not matter only the final stage, where the result is ultrapure water, but the pretreatment system, since it is at this stage where the greatest composition of contaminants is eliminated, these pretreatment processes are those that guarantee a purified water, which is used in different applications within the laboratories, an inefficient water purification system will affect the productivity of the laboratory, impairing the reliability of experiments and materials in use.
