The main concern with chemical treatment is the formation of disinfection by-products that are left behind in the water. In particular, chlorine is suspected to increase the levels of carcinogenic substances as a result of reactions with organic material in the water.
During the early days of water treatment, scientists discovered that in nature the sun was responsible for natural control of bacteria in rivers and lakes.
ESG Waterwise Ultra Violet Systems are designed to reproduce the power of the sun, producing ultra violet rays to destroy pathogenic micro-organisms within a matter of seconds.
Ultra Violet disinfection is a non-chemical treatment, destructive to all micro-organisms.
Ultra Violet light with a wavelength of 254 nm is the most effective range for disinfection, often referred to as the "Germicidal Range".
The Ultra Violet light penetrates the outer cell membrane of the organism, passing through the cell body, where it dissociates the DNA (deoxyribonucleic acid) structure of the organism, thus preventing further multiplication.
