In the present invention, dialysis tubing is placed in a chamber, where an ultrasonic or a other mist producer is present. The ultrasonic mist producer will produce mist and small water droplets will be attached to the surface of dialysis membrane (sheet or tubing) and will condense and the water drops will fall back in the solution tank, where the ultrasonic probe produces the mist. When the droplet is attached to the membrane surface, the dialysis will take place.
