The research was conducted to develop membrane separation system combined with ultraviolet radiation, ozonation, ultraviolet with hydrogen peroxide, biological treatment, granular filter and iron-packed bed.Fukita proposed design criteria of membrane separation system withoyt dosing alum and to minimize chlorine dosage in potable water treatment. He also found that coliforms and phages were completely eliminated by membrane separation, however, heterotrophic bacteria grew after membrane separation.Ohgaki found that phage was decreased to 0.001% order within 30 seconds contact by ozone and longer contact time was not effective. He also found that ultra-violet radiation was effective to inactivate the phage, however, the effectiveness was not enhanced by using together with hydrogen peroxide.Miya, proposed the most effective arrangement of ultra-violet lamps for ultra-violet treatment of secondary treated sewage.Yamamoto showed that nitrogen could be removed by combining membrane separation and intermittent aeration reactor and phosphate could be removed by zeolite-iron packed column.Several water treatment systems were proposed by combining above components.

研究开发了紫外光、臭氧氧化、紫外加过氧化氢、生物处理、颗粒滤池和铁填充床相结合的膜分离系统。Fukita提出了投加明矾的膜分离系统的设计准则，以最大限度地减少饮用水处理中的氯用量。他还发现，膜分离可以完全消除大肠菌群和噬菌体，但膜分离后异养菌生长。Ohgaki发现，臭氧作用30秒内，噬菌体降至0.001级，较长的接触时间无效。他还发现紫外线可以有效地灭活噬菌体，但与过氧化氢一起使用并不能提高灭活效果。Miya提出了紫外线灯对二级处理污水进行紫外线处理的最有效布置。Yamamoto表明，通过膜分离和间歇曝气反应器相结合可以去除氮，沸石-铁填充柱可以去除磷酸盐。
