For membrane filtration, maintenance management is very easy, and rejection performance of turbidity and bacteria is excellent. Since it is principally spreading on a small-scale water purification plant. Recentry, it is also expected to spread the middle and large-scale water purification plant. Therefore it is required the more efficient membrane filtration system, since it becomes mass processing by the large-scale water purification plant. By this study, it considers as a following subject: (1) Improvement in the water-purifying recovery rate by construction of a multi-stage membrane filtration system (2) Improvement in the stability and the water-purifying performance of the total membrane filtration system and the membrane filtration of each stage (3) Construction of an efficient method to watch over breaking hollow fiber (4) Examination of the recycling method for a disposal membrane module (5) Development and establishment of the chemical cleaning method, and examination of the non-chemical cleaning method (6) Evaluation and the proposal (case study) of efficient mass membrane processing technology For the purpose of establishing the design requirement of the membrane filtration water-purifying institution, it is an energy-saving and space-saving type at 10O,OOOm^3/day scale, the actual proof experiment is advanced. This paper reports the outline of this system and the result obtained until now.
