Impurities

Water has the unique ability to dissolve virtually every chemical compound, as well as support nearly every form of life.
Impurities

All laboratory water is initially sourced from a potable water supply, however, this water can contain many substances either in solution or in suspension which can impact and distort scientific data.

Water CycleThese contaminants have the potential to negatively impact on any number of scientific applications. Natural and drinking water contain a number of impurities which will be highlighted in this section of the site.

When it comes to your water purification system, it is important to know both your application and impurities are, as well as the state of your feedwater. If your feedwater is high in carbon dioxide then you may need an extra degasser module with your system; harder water areas may also require additional consumables for more effective running of your systems. Make sure that you know before you start looking to buy your next water purification system.

From drinking water to lab water

The main requirement for drinking water is that it conforms to international standards and has acceptable clarity, taste, and smell. The diagram below provides a brief overview of the water cycle, which highlights that natural water comes from upland sources such as reservoirs, rivers or underground aquifers. The quality of natural drinking water varies according to:

  1. Geography
  2. Season
  3. Source (surface or underground water)
