Abstract
There is no and end with the troubles such as in hospital accidents caused by the microorganisms such as Legionella pneumophila, Serratia marcescens, Pseudomonas aeruginosa, etc., not to speak of Staphylococcus aureus. The methods to remove these microorganisms come into operation with various kind of countermeasures, e.g. application of disinfectants, tools, microorganisms as objectives in the individual hospitals, dispensaries, and medical facilities. Meanwhile for removal of microorganisms, removal methods to be made use of in a wide range of utilization are required. Therefore in this study, ultra-fine ferromagnetic ferrite particles are first of all thrown into physiological saline solution. Secondly a concussion contacting test, bubbling test, and other such treatments were conducted. By so doing, this brought about good sterilization effect. Meanwhile when general stray bacilli are allowed to pass through a suspended liquid after a filter was dipped in the liquid by the use of a dehydrated filter, and good sterilization effect was obtained.
