20110108490 | 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 - An efficient filtration process of water from a tank is performed over a small volume of water and not on the totality of the water from the tank. The process includes emitting ultrasonic waves in the tank; and adding a flocculant agent to the water. The tank bottom is covered with a suctioning device which suctions a water flow with flocculated particles, discharging to a collecting effluent line and the effluent flow of the suctioning device is filtered from the collecting effluent line. Filtered flow is returned to the tank. A suctioning device is used in the efficient filtration process. | 05-12-2011 |
