1 反渗透工艺流程：全自动控制：PLC 自动控制，自动制水、反渗透膜自动冲洗、预处理自动反冲洗、水满自动停机、缺水保护，pH 值自动调节功能，非正常情况报警功能，高度自动化、智能化，使操作方便、简单直观。反渗透膜：美国进口反渗透膜，脱盐率高，耐污染易清洗，产品水水质稳定。纳滤简介原水经预处理后由高压泵加压进入纳滤膜，纳滤膜能截留物质大小约为 1 纳米(1 10-9 米),也就是纳滤膜能截留水中所有的悬浮颗粒、胶体、细菌病毒、分子量200-400 以上的有机物、重金属离子等，能保留水中部分对人体有益的元素，适合于饮用水设备。超滤简介原水经加压进入微过滤器，经过过滤孔径2 10-5 米的微滤膜滤除水中泥砂、胶体、藻类等在颗粒物质，然后进入孔径为 3-100 纳米（1 纳米 =10-9 米）的超滤膜，水中的小颗粒悬浮杂质、胶体、大分子有机物、细菌等小颗粒物质比截留在浓水中排放，透过超滤膜的为产品水。反渗透功能解析：1、石英砂过滤器：去除水中泥砂、铁锈、藻类、腐殖质、胶体等大颗粒悬浮杂质，降低浊度。2、活性炭过滤器：利用活性炭的广谱吸附性能，去除水中有机物、重金属离子、2 农药、洗涤剂、余氯等，除去异味、降低色度。3、保安过滤器：滤芯孔径为 5 微米，滤除水中微粒，确保水质符合反渗透膜进水的要求，减轻反渗透膜负荷。4、反渗透膜：水分子在压力作用下渗透通过反渗透膜，水中的有害离子、细菌、病毒等被截留，并随浓水排掉，透过的水即为纯净水。5、可选用配套设备：软化、杀菌、阻垢、药洗、变频供水等系统。反渗透原理 :对透过物质具有选择性的薄膜称为半透膜，一般将只能透过溶剂而不能透过溶质的薄膜称之为理想半透膜。当把相同体积的稀溶液（例如淡水）和浓溶液（例如盐水）分别置于半透膜的两侧时，稀溶液中的溶剂将自然穿过半透膜而自发地向浓溶液一侧流动，这一现象称为渗透。当渗透达到平衡时，浓溶液侧的液面会比稀溶液的液面高出一定高度，即形成一个压差，此压差即为渗透压。渗透压的大水取决于溶液的固有性质，即与溶液的种类、浓度和温度有关而与半透膜的性质无关。若在溶液一侧施加一个大于渗透压的压力时，溶剂的流动方向将与原来的渗透方向相反，开始从浓溶液向稀溶液一侧流动，这一过程称为反渗透。反渗透是渗透的一种反向迁移运动，是一种在压力驱动不借助于半透膜的选择截留作用将溶剂中的溶质与溶剂分开的分离方法，它已广泛用于各种溶液的提纯与溶缩，其中最普遍的应用实例便是在水处理工艺中，用反渗透技术将水中的离子、细菌、病毒、有机物及胶体等杂质去除，以获得高质量的纯净水。反渗透技术参数：反渗透水处理技术是当今世界最为普及也最为成熟的纯净水生产技术。反渗透纯水机的核心部件是反渗透膜，是利用反渗透原理，运用水压，使水由较高浓度的一方渗透至较低浓度一方，此时在较高浓度方的所有细菌及不纯杂物、可溶性固体物和对人体有害的有机物和无机物均不能渗入高精密的反渗透膜。反渗透膜是由美国太空总署研发，现已广泛应用于工业和民用领域，用高科技特殊材质精制而成，膜孔小于万分之一文档编码:CY5H8Z3V6M6

m。换言之，大肠杆菌比此膜孔约大五千倍。因此除了水分子及少量溶于水中的微量离子能反渗透外，其余一切均全部被拒于膜外瞬时即被高压水流冲出，由废水管道排除，水分子在反渗透膜内层再凝聚为H2O纯水，贮存于无菌压力水箱中。因此通过反渗透所生成的纯净水没有一般滤水器不可避免的二度污染及成为细菌温床之缺点。设备型号额定产水量尽寸规格(B L
