纳滤过程之所以具有离子选择性,是由于在纳滤膜上或者膜中有负的带电基团,它们通过静电互相作用,阻碍多价离子的渗透。纳滤膜可能的荷电密度为0.5~2meq/g

纳滤膜的分离原理

纳滤膜介于ROUF膜之间,对NaCL的脱除率在90%以下,反渗透膜几乎对所有的溶质都有很高的脱除率,但纳滤膜只对特定的溶质具有高脱除率;

纳滤膜主要去除直径为1个纳米(nm)左右的溶质粒子,截留分子量为100~1000,在饮用水领域主要用于脱除三卤甲烷中间体、异味、色度、农药、合成洗涤剂,可溶性有机物,CaMg等硬度成分及蒸发残留物质。

Q & A: MORE >>
  • 1.Central air conditioning yellow water how to do?
    A:
    Central air-conditioning chilled water and condensate water are recycled water, the cycle will be adsorbed in the air of dust, foreign bodies, etc., water will generate microorganisms, so require regular replacement of water, if dirty very interested, or even to add special cleaning agent Cleaning; if condensation in the condenser more scale, will result in cooling effect of central air conditioning decreased, electricity consumption increased, so also regularly open the cleaning condenser. The way to do this is to change the frequency of cooling water and condensate and to clean the condenser……
  • 2.Circulating cooling water algae growth in a lot of how to deal with?
    A:
    Circulating water due to nutrient concentration, temperature and summer prolonged sunshine, bacteria and algae to create a rapid breeding conditions. Much like the mucilage secreted by bacteria, it allows dust and chemical buoys floating in the water to bond together to form slimy sediments. A biofouling sludge attaches to the heat transfer surfaces of the host condenser Heat transfer filler), in addition to causing corrosion under the scale, but also to reduce the flow of circulating water, reducing heat exchange efficiency, increase power consumption and host load, in severe cases will plug the pipeline……
  • 3.Cooler fouling can clean it?
    A:
    Can be cleaned. Cooler fouling is generally divided into two types of tube fouling and tube fouling, as circulating water generally use soft water, so fouling tube generally does not appear, unless your circulating water is not soft water, remove the detergent first Use soft water cycle. Most of the cooler scaling is outside the tube scaling, there are two reasons for its study, first, the circulating water pipe is too high, because the spray water is generally used groundwater that is hard water, so if the tube temperature is too high will make the spray water temperature Rise, the formation of scale in the pipe wall, the second is spray water itself with high Mg and other elements, especially in mountainous areas, the water is relatively hard……
