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
First Claim
1. A process for filtration of water in a tank, wherein the process is adapted to eliminate turbidity from water in the tank, and wherein the process comprises:
- a. emitting ultrasonic waves into the water in the tank, wherein one or more ultrasonic wave emitters are positioned within the tank to broadcast the ultrasonic waves to the total volume of water in the tank and the ultrasonic waves are emitted into the water with a frequency of from 20 to 100 kHz and power in a range of about 10 W to about 45 W;
b. adding a flocculant agent to the water to flocculate suspended solids in the water;
c. suctioning a portion of water in the tank containing flocculated solids with a suctioning device to provide a suctioning device effluent flow, wherein the suctioning device suctions a water flow comprising settled flocculated solids from a bottom of the tank avoiding resuspension of flocculated solids, thereby providing for removal of the flocculated solids from the water in the tank without filtering the total volume of water in the tank;
d. discharging the suctioning device effluent flow to an effluent collecting line;
e. filtering the suctioning device effluent flow from said effluent collecting line to produce a filtered flow; and
f. returning the filtered flow to the tank.

Abstract
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.

26. A process for filtration of water in a tank, wherein the tank comprises a large recreational water body having a surface area of at least 6,000 m2, and wherein the process is adapted to eliminate turbidity from the large recreational water body by filtering only a portion of the total water volume in the tank and not the complete volume as in traditional filtration systems, wherein the process comprises:
-
a. emitting ultrasonic waves into the water in the tank, wherein one or more ultrasonic wave emitters are positioned within the tank to broadcast the ultrasonic waves to the total volume of water in the tank and the ultrasonic waves are emitted into the water with a frequency of from 20 to 100 kHz and power in a range of about 10 W to about 45 W; b. adding a flocculant agent to the water to flocculate suspended solids in the water, which in combination with the ultrasonic waves allows for a more efficient filtration process; c. suctioning a portion of water in the tank containing flocculated solids with a suctioning device to provide a suctioning device effluent flow, wherein the suctioning device suctions a water flow comprising settled flocculated solids from a bottom of the tank avoiding resuspension of such floccules, thereby providing for removal of the flocculated solids from the water in the tank without filtering the total volume of water in the tank as in traditional filtration systems; d. discharging the suctioning device effluent flow to an effluent collecting line; e. filtering the suctioning device effluent flow from said effluent collecting line to produce a filtered flow; and f. returning the filtered flow to the tank.
