纯水设备水处理的过滤流程
纯水设备的过滤步骤如下:
The filtering steps of pure water equipment are as follows:
净水:利用净水技术除去水中大量的有机成分、重金属离子、有害杂质及细菌,并保留对人体有益的微量元素.清澈、甘甜、富氧可直接饮用,称为净水.
Water purification: the use of water purification technology to remove a large amount of organic components, heavy metal ions, harmful impurities and bacteria, and retain the beneficial trace elements of the human body, clear, sweet, rich oxygen can be directly consumed, known as water purification.
纯净水:利用反渗透技术除去了水中有机成分、无机成分、重金属离子、有害杂质及细菌以及矿物质,可直接饮用,称为纯净水.
Purified water: the use of reverse osmosis technology to remove the organic components in water, inorganic components, heavy metal ions, harmful impurities and bacteria and minerals, can be directly consumed, known as pure water.
活性炭
Activated carbon
活性炭是一种微孔发达的碳化合物,有极其丰富的空隙结构(每克达1000平方米),因而具有极强的吸附性能,是水处理运用最普遍的净水材料之一.能够去除水中的异色、异味、有机物、余氯,改善水的口感.
Activated carbon is a porous carbon compound is developed, the gap structure extremely rich (per 1000 square meters, thus Donetsk) has strong adsorption capability, is one of the most commonly used water treatment water purification materials. To remove the odor, color, organic matter, residual chlorine, improve the taste of water.
微滤
Mf
过滤精度是一般在0.03-15微米,是一种以静压为推动力,利用网状过滤介质的筛介质的筛分作用进行分离的膜过程,微滤膜具有比较整齐、均匀的多孔结构,在静压差作用下,小于膜孔的粒子通过膜,比膜孔大的粒子被截留在膜表面,使大小不同的组分得以分离.
The filtering precision is generally 0.03-15 microns, is a kind of static pressure driven separation process by using membrane sieving effect sieve filtration medium medium mesh, microfiltration membrane has a porous structure is neat and uniform, the static pressure difference under film hole smaller than the particle through the membrane, membrane pore than large particles be trapped on the membrane surface, the different sizes of the group allocated to separate.
常见的各种PP滤芯,陶瓷滤芯等都属于微滤范畴,能过滤水中的泥沙、铁锈等大颗粒杂质.
All kinds of common PP filter, ceramic filter are microfiltration category, sediment, rust and other large particle impurities in the water can be filtered.
过滤精度在微滤与纳滤之间,其孔径范围在0.002微米-0.1微米,是一种利用压差膜分离技术,就是在压力作用下,原水从高压端过滤到低压端,超滤一般可滤除水中的铁锈、沁沙、胶体、细菌、大分子朋机物等有害物质,并能保留对人体有益的一些矿物质元素.是矿泉水、山泉水生产工艺中的核心部件.
The filtration precision between microfiltration and nanofiltration, the pore size of 0.002 microns -0.1 microns, is a kind of using pressure membrane separation technology, is under pressure from high pressure to low pressure water filtration end end, ultrafiltration can generally be removing rust, Qin sand, colloid, bacteria, and other harmful organic molecules. The material, and can retain some mineral elements beneficial to human body. Is a core component of mineral water, spring water in the production process.
纳滤
nF
纳滤膜介于反渗透膜和超滤膜之间,其特点是只对特定的熔质具有高脱除率,主要去除直径为一个纳米左右的溶质粒子,截留分子量为100-1000MWCO在饮用水领域主要用于脱除硬度成分、三卤甲烷中间体、异味、色度、农药、合成洗涤剂、可溶性有机物和蒸发残留物质.在很低压力下仍具有较高脱盐性能.对高硬度水进行软化、脱盐是纳滤膜应用的最大领域.
Nanofiltration membrane between reverse osmosis and ultrafiltration membrane, which is characterized with high removal rate of only melt specific, mainly removed as a solute particle diameter nm, the MWCO 100-1000MWCO is mainly used for removal of hardness components, three halogenated methane in body, odor, color, pesticide, synthetic detergent, the soluble organic matter and evaporation residues in drinking water. At very low pressure still has high softening, desalination performance. Desalination of high hardness water is the largest field of application of nanofiltration membrane.
反渗透
reverse osmosis
反渗透技术是美国60年代初研制用于太空的一种超高精度的利用压差的膜分离技术.其大原理是在原水一边加比上自然渗透压更高的压力,逆转自然渗透方向,把原压向RO膜的另一边纯净水中,这是和自然界中渗透相反的过程.
Reverse osmosis technology is a kind of ultra high precision by using the United States at the beginning of 60s to develop a space pressure membrane separation technique. Its principle is in the raw water side on natural osmotic pressure higher than the pressure, reversing the natural penetration direction, the pressure to the other side of the pure water in the RO film, which is the reverse osmosis the process and nature.
反渗透过滤精度在0.00001微米左右,理论上讲可滤除水中几乎一切的杂质(包括有害的和有益的),只能允许水分子通过.一般用于饮用纯净水、工业超纯水、医药超纯水的制造.反渗透技术需要对原水回压.利用控制系统可对反渗透膜进行反冲洗,提高膜的使用寿命.
Reverse osmosis filtration precision in 0.00001 micron, theoretically which can filter impurities (including water almost all harmful and beneficial), only allows water molecules to pass through. Generally used in drinking water, industrial manufacturing pharmaceutical ultra pure water, ultra pure water. Reverse osmosis technology needs to back pressure. Water backwash the use of reverse osmosis membrane control system, improve the service life of the membranes.
KDF是凯得菲的缩写,是一种高纯度的铜、锌合金,通过电化学氧化一还原进行水处理工作,它还可以清除水中高达99%的氯和水容铅、汞、镍、铬及其它可熔解金属.对控制细菌、真菌、污垢、水藻的滋生成效卓著.能在一定程度上,提高水的PH值,减少矿物质结晶以防止结垢.
KDF is the abbreviation of KDF, is a kind of high purity copper and zinc alloy by electrochemical oxidation reduction of water treatment, it can remove up to 99% of the chlorine and water containing lead, mercury, nickel, chromium and other metals. The melting control of bacteria, fungi, algae, water and dirt the breeding of outstanding achievements. To a certain extent, improve the pH of the water, reduce the mineral crystals to prevent fouling.
