反滲透膜是一種模擬生物半透膜制成的具有一定特性的人工半透膜,是反滲透技術(shù)的核心構(gòu)件。反滲透技術(shù)原理是在高于溶液滲透壓的作用下,依據(jù)其他物質(zhì)不能透過半透膜 而將這些物質(zhì)和水分離開來。反滲透膜的膜孔徑非常小,因此能夠有效地去除水中的溶解鹽類、膠體、微生物、有機(jī)物等。系統(tǒng)具有水質(zhì)好、耗能低、無污染、工藝簡單、操作簡便等優(yōu)點(diǎn)
Reverse osmosis membrane is a kind of artificial semi-permeable membrane with certain characteristics, which is the core component of reverse osmosis technology. The principle of reverse osmosis technology is that under the action of higher osmotic pressure than the solution, these substances and water are removed from the semi-permeable membrane according to other substances. The membrane aperture of reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter and so on. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation
