Abstract
A clean water system is single important building block of ecosystems and has an apparent relationship between healthy ecosystems and healthy people. The global water conditions have been deteriorated, the vital water resources should be kept clean. A development of new water purification technology is urgent nowadays, since the original biological treatments are not sufficient for the reason that they have some disadvantages, such as high cost and low efficiency. Thus, this paper presents the detailed experimental data about the development of the water purifier by a venturi-type nozzle with electrodes using electrochemical technology, called electrolysis. Several pairs of iridium/ruthenium-coated titanium plates were used as electrodes. Optimal applied current, number of electrodes and flow rate of water were decided for decomposition of representative solution(p-nitrosodimethylaniline). And the electrodes were installed in the tube with the venturi nozzle for generating cavitation. By the bubbly flow induced by electrolysis of the electrodes, the cavitation effect of water could be enhanced with relatively lower powered water pumps. Finally, the prototype of a water purifier with electrodes and venturi nozzle was developed and proved its advantages for decomposition of algal bloom. As a result, the energy saving high efficiency water purifier has been developed in this study.
