PROBLEM TO BE SOLVED: To provide a filter capable of easily obtaining much filtrate by energy-saved power from pollutant water of rivers, ponds, drinking juices, etc. SOLUTION: The filter has a filtration material consisting of a film type flat membrane having, as filtering pores, slit gaps of each distances of many superfine filaments. This filter is energy-saved, simple and high in performance, as compared with a filtration by a hollow-fiber separation membrane. COPYRIGHT: (C)2005,JPO&NCIPI
