Introduction
Loiteh Ltd is an official representative of ITT Water & Wastewater AB to work with ITT Wedeco UV and Ozone products in Estonia
UV radiation
UV radiation with the wavelength of 254 nm kills bacteria and viruses through influences on their cells DNA. The advantage of this method is that no chemicals are introduced into water. The water to be treated must be of very low turbidity and with very small iron content (turbidity < 1.0 NTU; total iron < 0.01 mg/l; color 0 deg.).
In Table below is given the radiation energy required for some bacteria and viruses inactivation.
Required UV254 energy (W • s/cm2) for water 99,9% disinfection
Mycobacterium tuberculosis | 10 000 |
Legionella pneumophila | 3 800 |
Escherichia Coli | 7 000 |
Hepatitis virus | 8 000 |
Poliovirus | 21 000 |
Salmonella typhimurium | 15 200 |
In practice it is recommended to apply higher doses of about 30 000 – 40 000 W • s/cm2.
