A new type of ultrasonic spray nozzle was fabricated employing a piezoelectric device. The spray nozzle was designed to disperse chemicals in a water treatment mixing tank. The piezoelectric properties in ultrasonic spray nozzles were optimized to improve the dispersion of chemicals. The piezoelectrics were packaged in an aluminum case with silicone resin for the aqueous solution proof packaging. Chemicals were dispersed with high efficiency and the chemicals consumption was reduced by the ultrasonic fine particle spraying. The concentration of Escherichia coli in mixing tank was decreased remarkably using ultrasonic spray nozzle dispersion compared to the conventional methods.

A new type of ultrasonic spray nozzle was fabricated with piezoelectric devices. The spray nozzle was designed for the chemicals dispersion in the water purification bath. The piezoelectric properties in ultrasonic spray nozzles were optimized for the better dispersion of chemicals for purification process. Ultrasonic spray nozzle was packaged in metal case with silicone resin for the water proof application.
