A water treatment apparatus comprises a monochromatic light source 4 whose axis coincides with a geometric centre in an entrance opening 3 in a section A in a water conduit 1. The section A is made of transparent material. A light beam emitted by the source 4 is interrupted periodically by a screen 5 which is attached to a core 6 on an electromagnet 7 which is connected in series, through a timer 8, to a circuit which comprises a coil 2 and an electrical voltage source. The invention can most advantageously be used in different spheres of agriculture and industry, where there is a requirement for water having stimulating properties.
