UV disinfection for swimming pools

A study conducted by researchers at
the University of Illinois, shows that
exposure to byproducts of chemical
disinfection commonly used in
swimming pools can cause early
ageing, birth defects, asthma and
bladder cancer. The findings suggest
that the best method of pool
disinfection is a combination of
ultraviolet (UV) treatment and
chlorine, rather than the traditional
method of chlorine treatment alone.

Hanovia offers a safer method of
non-chemical pool water disinfection
with its UV systems. Water circulating
through the pool is exposed to a
specific spectrum of UV light, which
is absorbed by micro-organisms’
DNA, resulting in permanent,
irreparable inactivation of the microorganism.

In addition, UV light initiates
photo-chemical and photo-oxidation
reactions that destroy chloramines,
the byproducts of chlorine disinfection.

This reduces the associated
health risks along with unpleasant
odours, eye and skin irritation, and
corrosion to pool hall structures.
