<p>The present invention relates to a process and apparatus for application of corrective agents, particularly agents for restricting proliferation of anabaena on water surfaces wherein the process comprises continuous withdrawal of a certain amount of water from the water surface, adding a corrective agent to water being so withdrawn and introducing the mixture being formed back onto the water surface. Apparatus for making the above-described process comprises a water nozzle (1) attached to a vessel, (7) whereby between the inlet and outlet thereof there is arranged an axial-flow pump (2) and an outlet of a corrective agent supply pipe (5). Said water nozzle (1) outlet portion (10) has the form of a Venturi tube with axis in the direction of the vessel (7) movement, wherein the supply pipe (5) outlet in the water nozzle (1) is at the point of the smallest cross section thereof.</p> |
