超濾膜/UF membrane：

在膜法分離技術中膜的微孔徑在0.03-0.1μm之間的過濾膜稱為超濾膜，而一般膠體體積均≥0.1m，乳膠>0.5um，大腸菌、葡萄球菌等細菌體積>0.2nm，浮物、微粒子等體積>5μm，因此超濾膜可以過濾出溶液中的細菌、膠體、懸浮物、蛋白質等大分子物質。

In the membrane separaion technology, the fitraton membrane wth micropore diameter between0.03-0.1 u m is caled ultrafraion membrane. Generaly,the volume of coloid is2 0.1 ym, atexis 2 0.5 ym, bacena such as Echerichia col and Staphylcoccus are 2 0.2 yum, suspended sods and paricles are more than 5 yM. herefore,uraltration membranecan filter out bacteria, colloids, suspended solids, proteins and other macromolecular substances in the solution.

超濾/Ultra-filtration：

• 超濾是一種膜分離技術，其膜為多孔性不對稱結構。過濾過程是以膜倆側的壓差為驅動力，以機械篩分原理為基礎的一種溶液分離過程，使用壓力通常為0.1-0.3Mpa。超濾膜分離過程曾被看作是一種單純的物理分離過程。

• 超濾通常用于制取礦泉水、山泉水，是以壓力為推動力，利用超濾膜不同孔徑分離液體中的雜質的過程。目前在水處理行業(yè)中，聚砜、聚丙烯及PVDF中空纖維式是組件應用最多。

• 超濾主要用于將溶液中的大分子、膠體和微粒與溶劑等小分子物質進行分離。目前，超濾的應用領域主要涉及食品、飲料、生物醫(yī)藥、精細化工、工業(yè)廢水處理與回用、地表水前期預處理、中水回用、礦井水前期處理等。

  
  

• Ultrafltaion is a kind of membrane searation tecnolay. is membrane is oorous and asummetic. The ftralon pnces is a kind ofsouion seoaration proces based on heorinciole of mechanical sievino, whichis driven by the pressure dierence between the two sides of he membrane.The oeraing pressureis usuay 0.-0.3ma. Ulrailralion membraneseparation process was once regarded as a simple physical separation process.

• Ultraftraton is usual used to produce mineral water and mountain sping water.tis a proces of eparating impurities from iquid by using ultrafraion membrane with diferent poresizes. At present, in the water treatment industry, polvsulfone, polpropvlene and PVDF hollow fiber are the most widely used component
