C. ro水什么意思呢

RO（Reverses Osmosis）即反渗透的水，亦即市售纯净水。

所谓的纯净水就是将天然水经过多道工序处理、提纯和净化的水。经过多道工序后的纯净水除去了对人体有害的物质、部分矿物质元素，同时除去了细菌，因此可以直接饮用。

纯净水，简称净水或纯水，是纯洁、干净，不含有杂质或细菌的水（H2O），如有机污染物、无机盐、任何添加剂和各类杂质，是以符合生活饮用水卫生标准的水为原水。市场上出售的太空水，蒸馏水均为纯净水。

在中国桶装饮用水市场上，主要有纯净水、矿泉水、泉水和天然水、矿物质水等，由于矿泉水、泉水等受资源限制；

而纯净水是利用符合国家生活饮用水标准的城市供水系统的水经过一定的生产流程进行生产，因此有效的避免了各类病菌入侵人体，能有效安全地给人体补充水份，具有很强的溶解度，因此与人体细胞亲合力很强，有促进新陈代谢的作用。

原理

顾名思义，逆渗透滤膜技术就是利用渗透的方法来从海水中提取出纯净的饮用水。

渗透的英文“Osmosis”一词来源于希腊文“Osmos”，意思是一种推动力。1748年，莱诺对渗透现象进行了研究，并首次作了实验纪录，发现用膀胱把水和酒精隔开后，水可以通过膀胱进入酒精，但酒精不能进入水。

根据科学的定义，渗透是某种溶剂通过半透膜（一种溶剂分子能通过，而溶质分子不能通过的薄膜）从低浓度到高浓度转移的现象。通过那种被称作“半透膜”的薄膜，我们可以对渗透现象看得更清楚。

半透膜是一种对透过物质有选择性的薄膜。利用一张只准水分子透过，不许盐分子透过的半透膜，将一个容器分成两半。在膜的两侧分别注入纯水和含盐水，让两侧的高度一样高。过了一段时间后，盐水的液面升高，纯水的液面下降，这是由于纯水一侧的水分子透过半透膜在向盐水那侧转移。

当渗透达到平衡时，盐水一侧的水柱高于纯净水一侧的水柱，这种现象产生于所谓的“渗透压”，这渗透压的高低取决于盐水浓度的高低。

D. 净水器中的RO反渗透是什么意思

反渗透是60年代发展起来的一项新的膜分离技术，是依靠反渗透膜在压力下使内溶液中的溶剂与溶质进行分容离的过程。反渗透的英文全名是“REVERSEOSMOSIS”，缩写为“RO”。

RO反渗透膜孔径小至纳米级，在一定的压力下，水分子可以通过RO膜，而源水中的无机盐、重金属离子、有机物、胶体、细菌、病毒等杂质无法通过RO膜，从而使可以透过的纯水和无法透过的浓缩水严格区分开来。

因为RO膜能够有效去除水中钙、镁、细菌、有机物、无机物、金属离子和放射性物质等，RO反渗透膜的净水器适用于家庭和宾馆、酒店、医院等企事业单位饮用净水使用，净化出的水晶莹清澈、甜美甘醇。

安吉尔净水器足够专业，其产品具备长效反渗透膜：打破国外技术垄断的”中国芯，中国净水技术的全球突破，获全球十大创新专利，六大国际权威认证，精度达到0.0001微米，可以过滤细菌、病毒、重金属等水中的几乎一切杂质。

E. ro反渗透净水器是什么意思

RO逆渗透是一种通过国际流行的反渗透等办法，对原水进行过滤处理（物理法）后不添加任何化合物而生产出可供人类直接饮用的纯净水机器（也称为终端净水设备）。
反渗透净水机一般需要五级过滤：
第一级PP棉滤芯，5μm孔径滤芯，去除水中残留的泥沙、铁锈等杂质。
第二级前置颗粒碳滤芯，多用木质、煤质、果壳等含碳物质。它有非常多的微孔和比表面积，具有很强的吸附能力，能有效吸附水中的污染物。
第三级压缩活性炭滤芯：进一步去除水中余氯、异味及固体杂质。
第四级RO反渗透膜滤芯：有效去除水中钙、镁、细菌、有机物、无机物、金属离子。
第五级后置活性炭，改善口感，晶莹清澈、甜美甘醇。长期饮用RO膜过滤过的水质，不含对身体有害的物质，将对身体有益的矿物质保存了下来，长期饮用不会给身体带来副作用。

F. ro纯水是什么水

ro纯水一般称呼纯净水。

这样的水基本不保留水中的矿物质，PH值在6-7之间，为弱酸性，一般用于透析等医疗用水，或实验室，电子化工等特殊用水，由于水质污染严重，为保障饮水安全，也用于日常饮水，是卫生，安全的饮用水。

RO纯水技术由来

RO逆透纯水机源于美国太空技术，在90年代引入我国。逆渗透（原文Reverse Osmosis）是一种薄膜分离技术，依靠逆渗透膜在压力下，使溶液中的溶剂与溶质分离的过程。逆渗透是在有盐份的水中（如原水）施加比自然渗透压力更大的压力，使水由浓度高的一方渗透到浓度低的一方，把原水中的水分子和其他的物质分离。

由于逆渗透膜上的微孔极小，其孔隙仅为0.001μ,是细菌、病毒体积的几千分之一。采用该技术制备的水为纯水，不含有任何矿物质和微量元素，甚至尿经它过滤后都可以直接饮用。水通过逆渗透膜的速度极低，所以处理水量较小（4吨原水=1吨饮用水+3吨废水）。

G. 关于纯净水的英文文章

定义
Purified water is water from any source that is physically processed to remove impurities. Distilled water and deionized water have been the most common forms of purified water, but water can also be purified by other processes including reverse osmosis, carbon filtration, microporous filtration, ultrafiltration, ultraviolet oxidation, or electrodialysis. In recent decades, a combination of the above processes have come into use to proce water of such high purity that its trace contaminants are measured in parts per billion (ppb) or parts per trillion (ppt). Purified water has many uses, largely in science and engineering laboratories and instries, and is proced in a range of purities.

几种纯净水的方法形式Methods of water purifing
Distilled water has virtually all of its impurities removed through distillation. Distillation involves boiling the water and then condensing the steam into a clean container, leaving nearly all of the solid contaminants behind. Distillation proces very pure water but also leaves behind a leftover white or yellowish mineral scale on the distillation apparatus, which requires that the apparatus be frequently cleaned.
For many applications, cheaper alternatives such as deionized water are used in place of distilled water.
Double-distilled water (abbreviated "ddH2O", "Bidest. water" or "DDW") is prepared by double distillation of water. Historically, it was the de facto standard for highly purified laboratory water for biochemistry and trace analysis until combination methods of purification became widespread.
Deionized water which is also known as demineralized water (DI water or de-ionized water; can also be spelled deionised water, see spelling differences) is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization proces a high purity water that is generally similar to distilled water, and this process is quick and without scale builp. However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin. Specially made strong base anion resins can remove Gram-negative bacteria. Deionization can be done continuously and inexpensively using electrodeionization.
It should be noted that deionization does not remove the hydroxide or hydronium ions from water; as water self-ionizes to equilibrium, this would lead to the removal of the water itself.
Other processes are also used to purify water, including reverse osmosis, carbon filtration, microporous filtration, ultrafiltration, ultraviolet oxidation, or electrodialysis. These are used in place of, or in addition to the processes listed above.

饮用纯净水Drinking purified water
Many beverage manufacturers use distilled water to ensure a drink's purity and taste. Bottled distilled water is sold as well, and can usually be found in supermarkets. Water purification, such as distillation, is especially important in regions where water resources or tap water is not suitable for ingesting without boiling or chemical treatment.
Water filtration devices are becoming increasingly common in households. Most of these devices do not distill water, though there continues to be an increase in consumer-oriented water distillers and reverse osmosis machines being sold and used. Municipal water supplies often add or have trace impurities at levels which are regulated to be safe for consumption. Much of these additional impurities, such as volatile organic compounds, fluoride, and an estimated 75,000+ other chemical compounds[citation needed] are not removed through conventional filtration; however, distillation and reverse osmosis eliminate nearly all of these impurities.
The drinking of purified water has been both advocated and discouraged for health reasons. Purified water lacks minerals and ions, such as calcium, which are normally found in potable (drinking) water, and which have important biological functions such as in nervous system homeostasis. Some percentage of our daily consumption of these minerals and ions come from our drinking water, but most of them come from the food we eat, making DI water perfectly fine to drink if one has food in his or her system. The lack of naturally-occurring minerals in distilled water has raised some concerns. The Journal of General Internal Medicine[3] published a study on the mineral contents of different waters available in the US. The study concluded, "drinking water sources available to North Americans may contain high levels of Calcium, Magnesium, and Sodium and may provide clinically important portions of the recommended dietary intake of these minerals," and further encouraged indivials to "check the mineral content of their drinking water, whether tap or bottled, and choose water most appropriate for their needs." Since distilled water is devoid of minerals, supplemental mineral intake through diet is needed to maintain proper health.
It is often observed that consumption of "hard" water, or water that has some minerals, is associated with beneficial cardiovascular effects. As noted in the American Journal of Epidemiology, consumption of hard drinking water is negatively correlated with atherosclerotic heart disease.[4] Since distilled water is free of minerals, it will not have these potential benefits.
It has been suggested that because distilled water lacks fluoride ions that are added by a minority of governments (e.g., municipalities in the United States) at water treatment plants using sodium hexafluorosilicate or hexafluorosilicic acid for their effect on the inhibition of cavity formation: the drinking of distilled water may increase the risk of tooth decay.[citation needed] However, many medical authorities argue that the effects of fluoridation on teeth are topical (brushed on) rather than systemic (swallowed). Also the benefit of fluoride supplementation, for any purpose, should be cautioned e to potential negative effects to IQ and motor functions.
The costs associated with water distillation have generally been prohibitive. However, distilling water with solar water distillers is becoming increasingly popular around the world; they can be relatively simple to design and build.

H. 净水器里的RO膜的作用是什么

使溶液中的溶剂与溶质进行分离。

一般滤水器的构造以活性碳与树脂为主要结构，其主要功能，只是过滤一些较大杂质及除臭功能，一旦滤水器中留有物增多，就成为细菌的温床、大肠杆菌繁殖区。

而纯水机的RO膜是高科技的产品，可以将比水分子大的分子完全排除掉，使重金属及杂质与水分子完全分开，反渗透纯水机制造的水才是真正干净的水。

RO反渗透技术是利用渗透压力差为动力的膜分离过滤技术，源于美国二十世纪六十年代宇航科技的研究，后逐渐转化为民用，已广泛运用于科研、医药、食品、饮料、海水淡化等领域。

I. 净水器OR纯水机与超滤机有什么区别我老家北方的，应该如何选择安装什么样的净水器

超滤是一种利用膜分离技术的筛分过程，以膜两侧的压力差为驱动力，以超滤膜为过滤介质，在一定的压力下，当原液流过膜表面时，超滤膜表面密布的许多细小的微孔只允许水及小分子物质通过而成为透过液，而原液中体积大于膜表面微孔径的物质则被截留在膜的进液侧，成为浓缩液，因而实现对原液的净化、分离和浓缩的目的。每米长的超滤膜丝管壁上约有60亿个0.01微米的微孔，其孔径只允许水分子、水中的有益矿物质和微量元素通过，而最小细菌的体积都在0.02微米以上，因此细菌以及比细菌体积大得多的胶体、铁锈、悬浮物、泥沙、大分子有机物等都能被超滤膜截留下来，从而实现了净化过程。这就是超滤净水器的工作原理。

RO纯水机是利用反渗透技术原理进行水过滤的净水机。RO（ReverseOsmosis）反渗透技术是利用渗透压力差为动力的膜分离过滤技术。RO反渗透膜孔径小至纳米级（1纳米=10的负9次方米），在一定的压力下，水分子可以通过RO膜，而源水中的无机盐、重金属离子、有机物、胶体、细菌、病毒等杂质无法通过RO膜，从而使可以透过的纯水和无法透过的浓缩水严格区分开来，透过RO膜过去的那部分水就是纯水。

北方的水质比较硬，净水器应该选用反渗透的，也可以选择空气制水机

J. OR纯水是什么
