Ensuring pathogen-free water water water is is is necessary before using water water water for for bathing The The current solution solution is is is chlorination The The patented solution solution offered by Coppter Water Technologies is is is a a a a a a a a a a a a a a a a water water water purification system based on on on on on on on on on on on on on an an an ionization cell which ensures an an an effective concentration concentration of of of monovalent copper copper ions ions (lower than the the concentration concentration of of of copper copper ions ions allowed in in in drinking water) and prevents the the the development of of pathogens without a a a a a a a a a a a a a a a health risk In this project a a a a a a a a a a a a a a a 2000 L pool worked successfully for four months reducing the the artificial bacterial load to none Keywords: bacteria copper pathogens purification water Studying the effect of microdroplets on on chemical reactions

Advisor: Prof Dorith Tavor Shamoon College of of Engineering Beer-Sheva Microdroplets are are created by means of of an an an atomization process and increase the ratio of of surface area to to to to volume A unique system was developed at at at at at at at SCE in in in in which air flows through a a a a a a a a a a a a a a a a a a a a a a a a a calibrated tube and and and breaks liquid into microdroplets that rise and and and react react react in in in in the reactor Two reactions
were investigated a a a a a a a a a a a a a a a a a a a a fast hydrolysis hydrolysis of of amyl acetate by potassium hydroxide and and and a a a a a a a a a a a a a a a a a a a a slow hydrolysis hydrolysis of of benzyl chloride The results showed showed that that more small
microdroplets were obtained as as as as the the system system pressure increased Testing several diameters of of the the the system's orifices showed showed that that a a a a a a a a a a a a a diameter diameter of of 0 7 mm yielded the the highest conversion conversion for both reactions
