Understanding Lab Water Purification Systems
Water is the most used reagent in laboratories. Impure water can significantly affect the accuracy and reliability of lab research and results. Contaminants and impurities at the bench can impact consistency and reproducibility by altering the behaviour of reactions and skewing analytical measurements, ultimately leading to unreliable and variable experimental outcomes.
With the help of laboratory water purification systems, laboratories can ensure that the water in their lab reaches the required level of purity. There are a number of regulations and standards that require laboratories to make sure that all experiments are carried out with the appropriate grade of water.
In this blog post, we will explore different lab water purification systems (also known as laboratory benchtop units) that you can use to generate lab pure water (type 1, 2 and 3).
Reverse Osmosis (RO) systems
Reverse Osmosis (RO) systems use a synthetic semipermeable membrane designed to only allow water molecules to pass through while blocking larger molecules and ions like salts, bacteria, and other contaminants. The process involves applying pressure to overcome the natural osmotic pressure, pushing water through the RO membrane, and leaving the impurities behind. This makes Reverse Osmosis an effective method for purifying water for general use in the laboratory.
Deionisation (DI) Systems
DI systems remove ions from water by using ion exchange resins. Charged particles to be removed include calcium ions, magnesium ions, sodium ions, and chloride ions. This technology typically follows the RO process to enhance the quality of the purified water by reducing the ions further and increasing the resistivity up to 18.2 megaohm.
Distillation Systems
Distillation systems involve the heating of water, converting it to steam, and then re-condensing it to water. It is effective against bacteria, viruses, and Bio-VOCs. However, it is time-consuming and is a high energy demand solution.
Ultraviolet (UV) sterilisation systems
UV light is used to destroy bacteria, viruses, and other microorganisms in UV sterilisation systems. They don’t remove other forms of contaminants or change the chemical state of the water but are rather utilised to guarantee microbial purity in applications that are very sensitive.
Electro deionisation (EDI) systems
The EDI system produces ultra-purity water through the continuous regeneration of ion exchange resins and membranes, using an electric current. It incorporates ion exchange and electrochemistry to make water with very low conductivity and purity.
