Abstract

Recently, people are very conscious about water saving in view of chronic shortages of water and the environmental issues. In this study, we have conducted the comparison and verification of the air-bubble effect against city water spouts with air-bubble generated by the co-developed nozzle. The nozzle, ETC nozzle, is designed for water consumption volume and cost saving. A resistance strain gauge technology, a high-speed camera technology and a photocatalysis technology was used on the nozzle evaluation.
