超纯水最初是美国科技界为了研制超纯材料(半导体原件材料、纳米精细陶瓷材料等)应用蒸馏、去离子化、反渗透技术或其它适当的超临界精细技术生产出来的水，如今超纯水已在生物、医药、汽车等领域广泛应用。这种水中除了水分子(H20)外，几乎没有什么杂质，更没有细菌、病毒、含氯二恶英等有机物，当然也没有人体所需的矿物质微量元素，超纯水无硬度，口感较甜，又常称为软水，可直接饮用，也可煮沸饮用。超纯水,是一般工艺很难达到的程度，如水的电阻率大于18MΩ*cm，接近于18.3MΩ*cm则称为超纯水。
Ultra pure water was originally produced by the US technology community using distillation, deionization, reverse osmosis, or other appropriate supercritical fine technologies to develop ultra pure materials (semiconductor raw materials, nano fine ceramic materials, etc.). Nowadays, ultra pure water has been widely used in fields such as biology, medicine, and automobiles. This type of water has almost no impurities except for water molecules (H20), and there are no organic substances such as bacteria, viruses, and chlorine dioxins. Of course, it also does not have the necessary mineral trace elements for the human body. Ultra pure water has no hardness, has a sweet taste, and is often referred to as soft water. It can be consumed directly or boiled for drinking. Ultra pure water is a level that is difficult to achieve in general processes. If the resistivity of water is greater than 18M Ω * cm and close to 18.3M Ω * cm, it is called ultra pure water.
采用预处理、反渗透技术、超纯化处理以及后级处理等方法，将水中的导电介质几乎完全去除，又将水中不离解的胶体物质、气体及有机物均阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具去除至很低程度的水处理设备。
A water treatment equipment that uses pre-treatment, reverse osmosis technology, ultra purification treatment, and post treatment methods to almost completely remove conductive media from water, while also removing non dissociative colloidal substances, gases, and organic substances to a very low level.
超纯水系统设备的脱盐核心部件为进口反渗透膜组件，超纯水系统设备通常由预处理部分，反渗透主机部分，后处理部分共同组成。
The desalination core component of the ultra pure water system equipment is the imported reverse osmosis membrane component. The ultra pure water system equipment is usually composed of a pre-treatment part, a reverse osmosis host part, and a post-treatment part.
1、预处理由石英砂过滤器、活性碳过滤器、全自动软水器、精密过滤器组成(我司采用全自动控制阀头)，也可选用超滤系统作为预处理，但通常工程造价要高。预处理主要目的是去除原水中含有的泥沙，铁锈、胶体物质、悬浮物、色度、异味、生化有机物。当原水中硬度较高时，可选择全自动软水器，这样有效的保护了反渗透膜，从而延长了反渗透膜的使用寿命。
1. The pre-treatment is composed of quartz sand filter, activated carbon filter, fully automatic water softener, and precision filter (our company adopts fully automatic control valve head), and ultrafiltration system can also be used as pre-treatment, but the project cost is usually high. The main purpose of pre-treatment is to remove sediment, rust, colloidal substances, suspended solids, chromaticity, odor, and biochemical organic matter contained in the raw water. When the hardness of the raw water is high, a fully automatic water softener can be selected, which effectively protects the reverse osmosis membrane and extends its service life.
