Solidifying of molten or over saturated solution materials

The invention concerns the exploitation of the process of initiating and/or accelerating and/or controlling crystallization or precipitation in supercooled melts or supersaturated solutions of solids. A problem frequently encountered with this process is that the duration of the process of solidification or crystallization cannot be precisely controlled or the process does not continue long enough to allow adequate solidification or crystallization. According to the present invention, the supercooled melt or supersaturated solution is exposed to ultrasound before being delivered to the conveyor belt in a belt system or while being discharged onto a conveyor belt, or before being delivered to a receptacle drum or while it is fed into a receptacle drum.

Localised energy concentration

ULTRASONIC PARTICLE-SEPARATOR

The movement of particles in a liquid flowing in a duct (2) is controlled by an ultrasonic standing wave having nodal fronts at a small angle to one pair of side walls of the duct. As the liquid flows along the duct, particles responsive to the acoustic energy are held on the oblique nodal fronts and are carried along these by the flow so that they also move towards one side wall (2a). Particles in the vicinity of that one side wall are swept from the nodal fronts by the liquid drag forces. At the duct exit the particles will therefore tend to be concentrated in that portion of the liquid flow that passes nearer said one wall (2a).

Treatment of water

A method of treatment of water contaminated with impurities such as cryptosporidia oocysts includes subjecting the water to an ultrasonic vibration at frequencies of 20,000 Hz or higher sufficient to either rupture cellwalls of the oocysts or make them non-viable thus removing the risk from cryptosporidia and rendering the water potable. Water contaminated with giardia organisms, pesticidal compounds and organic compounds may also be so treated.
