Abstract
A method and a system is provided for inactivation of Infectious Pancreatic Necrosis Virus (IPNV) comprising illuminating a liquid containing IPNV with a lamp emitting a continuous broad band of ultraviolet (UV) light. The UV lamp may be “tuned” to optimize IPNV inactivation. The lamp may be a medium pressure UV lamp that emits UV light having wavelength between 260-400 nm and preferably, between 260-300 nm. The pressure of the lamp may be greater than 1.6 bar, 3 bar and preferably is 7 bar. The lamp may be composed of PS (synthetic quartz).
Claims14
An ultraviolet (UV) liquid treatment apparatus comprising:
- a conduit having an inlet to receive liquid to be treated containing Infectious Pancreatic Necrosis Virus (IPNV) and an outlet to discharge treated liquid;
- and
- a UV lamp tuned to optimize IPNV inactivation,
- wherein the lamp is a polychromatic lamp that emits UV light substantially in a wavelength range between 260 and 400 nm and exhibits a pressure greater than 1.6 bar or a monochromatic lamp that emits in a single wavelength selected from a wavelength range between 260 and 400 nm.
