Iron is one of the most common elements in ground water. Bythe HN 24:2003 iron concentration in water can‘t be higher than200 μg/l. Water treatment with an acoustic field is a very relevanttopic. Acoustic field is widely used in industrion, medicine,chemical industry and manufacturing. When water is affectedby ultrasound, physical-chemical processes begin. Ultrasoundvibrations lead to dispersion, degasation and coagulation. Ironparticles connect to each other when distance between them istwo times bigger then their own radius. R = 2R. And if thisprocess continues particles connect one by one. In this article teststand and methodics using ultrasonic piezoceramic are shown
