Water purifying method and system. |
摘要 |
<p>Water contaminated by small amounts of bacteria, pyrogens and iow molecular weight organic compounds is treated by passing said contaminated water through a microporous polyolefin membrane having a multitude of rectangularly shaped nodule areas, each nodule area containing a plurality of strip-like microfibrils arranged in a longitudinal direction from one surface of a nodule to the side opposite said surface thereby forming a plurality of strip-like micropores in each nodule, said micropores being contiguous with each other from one surface to the other surface of the membrane thereby forming a micro-stacked structure, the mean pore diameter of said micropores ranging from 0.03 to 0.8 p.</p> |
