| | There are two common methods of
disinfecting water, chlorine and ultraviolet (UV) treatment.
Chlorine,
in the past, has been more widely accepted than UV.
Recently, however, chlorine has been strongly criticised. It not only
affects water taste and odour as it disinfects, more importantly, research
suggests that chlorine
produces cancer causing by-products.
Chlorine
|
UV
(Nature Flow
Treatment System)
|
|
Long
retention time required (20-45 minutes).
|
Fast
disinfection (3-5 seconds).
|
|
Corrosive.
|
Non-Corrosive.
|
|
Has
a distinctive odour, can be tasted, and modifies pH, connected with the
production of carcinogens.
|
Does
not affect odour, taste, pH, chemical composition, and does not leave any
harmful by-products.
|
|
High
maintenance.
|
Low
maintenance.
|
|
Expensive
to run.
|
Generally
cheaper to run than chlorine.
|
|
Sodium
Hypochlorite degrades back into sodium chloride (salt) and therefore it
becomes inactive on storage.
|
Lamps
only need replacing when recommended hours have been reached.
|
|
Hazardous
when transporting, storing, and handling.
|
No
hazardous chemical.
|
Ultraviolet
disinfection solves the environmental and safety problems associated with
chlorination whilst being reliable, efficient and cost effective.
