Abstract
A fluid treatment apparatus comprises a duct portion (10) having an elongated tubular duct (12), inlet and outlet ports at or adjacent opposite ends of the duct (12), a separate vane portion (11), mounted internally of the duct (12) and carrying a helical guide vane (17), which extends longitudinally of the duct (12) between said inlet and outlet ports (13,14) to promote a helical fluid flow therebetween, and an elongated ultra-violet light source (22) extending longitudinally of the duct (12). The helical guide vane (17) is formed on the separate vane portion (11) f the apparatus and thus the apparatus is simple to construct, since the helical guide vane (17) is formed prior to insertion into duct (12).
