Overview of electroplating ultra pure water equipment

电镀涂装表面处理行业中，根据电镀工艺要求;为了增加镀件表面光洁度、亮度、附着力等电镀液的配制需要用产水电导率在15us/cm以下的纯水。另外在镀件漂洗时也需用产水电导率在10us/cm以下电镀纯水来清洗，电镀行业用纯水系统主要是电镀前的电镀液配制用及电镀件漂洗用纯水系统;另外针对电镀漂洗后的废水中稀有金属回收,漂洗水循环利用电镀纯净水设备零排放系统。

In the plating coating surface treatment industry, according to the requirements of electroplating process, in order to increase the surface finish, brightness, adhesion and other electroplating solutions of the plating, the pure water with water conductivity below 15us/cm needs to be used. In addition, the water conductivity of the plating water should be washed with pure water below 10us/cm when the plating bath is rinsed. The pure water system used in the electroplating industry is mainly made up of electroplating solution before electroplating and the pure water system for the rinsing of electroplating parts. In addition, the recycling of rare metals in the waste water after electroplating and the recycling of the rinse water with the zero discharge of the electroplated pure water equipment is used. System.

涂装电镀纯水设备主要是利用反渗透技术来制取纯水,通过反渗透膜制取的纯水电导率可达10us/cm以下。反渗透纯净水设备技术是当今最先进和最节能有效的膜分离技术。其原理是在高于溶液渗透压的作用下,依据其他物质不能透过半透膜而将这些物质和水分离开来。由于反渗透膜的膜孔径非常小,过滤精度0.0001微米,系统产水脱盐率可达99%左右。因此能够有效地去除水中的溶解盐类、胶体、微生物、有机物等去除率高达97%-98%。反渗透纯水设备具有产水水质好、耗能低、无污染、工艺简单、操作简便等优点。目前被广泛应用于工业纯水制取工艺上。

The main purpose of coating pure water equipment is to use reverse osmosis technology to produce pure water. The conductivity of pure water prepared by reverse osmosis membrane can reach below 10us/cm. Reverse osmosis pure water technology is the most advanced and energy-efficient membrane separation technology. The principle is to separate these substances from water under the action of higher osmotic pressure than other substances. Because the membrane diameter of reverse osmosis membrane is very small, and the filtration accuracy is 0.0001 microns, the desalting rate of the system is about 99%. Therefore, the removal rate of dissolved salts, colloid, microorganism and organic matter can be effectively up to 97%-98%. Reverse osmosis pure water equipment has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation. At present, it is widely used in industrial pure water production process.
