Aseptic water for medical use can be obtained by ultra-microfiltration system. However, sometimes bacteria contamination was found in the filtration circuit. This study was done to investigate the efficacy of an apparatus producing hypochlorous acid. Prior to placing of this apparatus, water contaminations of the circuit had been investigated for 3 years. Bacteria were observed 8 times out of 128 tests in first usage of the system in early morning. The main cause of contamination was thought to be the back flow from the faucet to the circuit. This problem was soloved by placing the apparatus between the ultra-microfilter and the faucet to keep the concentration of chloride about 130 ppm in the circuit. After placing of this apparatus, no babteriq has been found. In conclusion, this apparatus is effective for preventing bacteria contamination of the filtration system.
