| abstract |
A method and a device for the restriction of blooms of micro-organisms in an aqueous system are described. A smaller portion of the body of water in the system is subjected to a radiation treatment, preferably a UV-treatment, whereupon the treated quantity of water is returned to the aqueous system. The UV radiation will induce activation of latent viruses, and when these are returned to the water system, micro-organisms in this system will be killed or inactivated, and new micro-organisms will not be formed. |
