Efficient filtration process of water in a tank for recreational and ornamental uses, where the filtration is performed over a small volume of water and not over the totality of the water from the tank

Abstract

The present invention comprises an efficient filtration process of water from a tank, whore the filtration is performed over a small volume of water and not on the totality of the water from the tank: the process comprises the following steps: (a) emitting ultrasonic waves in the tank: (b) adding a flocculant agent to the water: (c) covering the tank bottom with a suctioning device which suctions a water flow with flocculated particles, discharging to a collecting effluent line: (d) filtering the effluent flow of the suctioning device from said collecting effluent line; and (e) returning the filtered flow to the tank. The present invention additionally comprises a suctioning device used in said efficient filtration process.
