Title:
FILTER FOR FILTRATION COLLECTION OF PARTICLES FLOATING IN WATER, AND METHOD FOR FILTRATION COLLECTION OF PARTICLES FLOATING IN WATER AND METHOD FOR CONTROL OF WATER QUALITY USING THE FILTER
Document Type and Number:
WIPO Patent Application WO/2008/015792
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a novel filter for use in the filtration collection of particles floating in water which can filtrate particles floating in water readily and quickly and can collect the particles with efficiency, and to provide a method for the filtration collection of particles floating in water. [MEANS FOR SOLVING PROBLEMS] A filter comprising a substrate and a porous soluble powder accumulated on the substrate. Particles floating in water are physically filtrated by using the filter. Subsequently, the soluble powder in the filter is dissolved with an acid to collect the filtrated particles.
