| abstract | (57) [Summary] [PROBLEMS] To remove chlorine-resistant protozoa using a membrane filtration device and to make available existing facilities. SOLUTION: A disinfection device 20 for a water purification facility and a water purification pond 24 are provided. In between, a membrane filtration device 22 is provided. This membrane filtration device 22 The water to be treated is water that has been treated in advance by the coagulation sedimentation device 16 and the rapid filtration device 18 and has a water quality that can be distributed. Thus, the membrane filtration device 22 can perform low-pressure, high-flow-rate processing for the purpose of removing only the chlorine-resistant protozoa. Thereby, the chlorine-resistant protozoa can be reliably and efficiently removed. Existing facilities other than the membrane filtration device 22 can be used, and this facility can be configured by modification. |
