Patent ID: 8883684

Claim:
A process for treating with at least one chemical compound a body of water comprising at least one living organism selected from the group consisting of fish, mollusks, crustaceans and aquatic plants, said process comprising adding said at least one chemical compound to the body of water and agitating the water with an agitation system, wherein said agitation system comprises a centrifugal pump located on the deck of a well boat, at least one submerged pipe located into the well, and several outlets, wherein each said outlet is equipped with an eductor nozzle, and a connecting pipe connecting said centrifugal pump to said submerged pipe, wherein said connecting pipe comprises a flow meter to measure the flow of a pumped liquid (A) sent to the body of water to be treated, and wherein said eductor nozzle comprises: a nozzle part ( 1 ) through which exits said liquid (A) pumped through the agitation system via the centrifugal pump, wherein said liquid (A) comprises the chemical compound an eductor part ( 3 a ) through which part of the water present in the body of water to be treated is sucked, via at least one suction opening ( 2 b ), said sucked water flow being called induced liquid (B), and a diffuser part ( 3 b ) in which the pumped liquid (A) and the induced liquid (B) are mixed and exit from the agitation system in the form of a total outlet flow (C), wherein the eductor nozzle is such that the total outlet flow (C) exiting the eductor nozzle is from 4 to 6 times greater than the pumped liquid (A) flow rate exiting the nozzle part of the eductor nozzle.
