Laboratory Water Purification Overview

Water for most laboratory and clinical applications is usually purified from drinking water.  Impurities must be removed and additional contamination from water purification components and bacterial growth managed effectively. Depending on the water quality required, a number of purification technologies are used to remove these impurities. It is vital to use a combination of water purification technologies to effectively remove contaminants to levels required for critical applications.

Types of water purification technologies

Water purification technologies are efficient at removing specific types of impurities down to very low levels in the parts per billion (ppb) and parts per trillion (ppt) range. Others are able to remove a large proportion of several impurities and contaminants. In general, the technologies used in water purification systems have remained relatively unchanged over the past decades.
