A solution: Going ultraviolet

摘要

The water industry, with good reason, is very conservative and the familiarity of chemical disinfection by chlorine or ozone, easily monitored by redox potential, is somehow reassuring whilst monitoring electromagnetic radiation is largely unfamiliar - in spite of the fact that the pharmaceutical industry has relied on UV disinfection for over a quarter of a century. However, more and more water companies are discovering that UV as a primary disinfection strategy reduces the environmental, health and safety risks associated with large scale chlorination or ozonation and gives significant savings in both capital equipment expenditure and operational costs.
