工业锅炉水处理方法很多总体可分为锅外水处理和锅内水处理。锅外水处理主要是水的软化,即在水进入锅炉之前,通过物理的、化学的及电化学的方法除去水中的钙、镁硬度盐和氧气,防止锅炉结垢和腐蚀。锅内水处理就是往锅炉 (或给水箱、给水管道)内投加药剂达到防止或减轻锅炉结垢和腐蚀的目的。
反渗透设备是将原水经过精细过滤器、颗粒活性碳过滤器、压缩活性碳过滤器等,再通过泵加压,利用孔径为1/10000μm(相当于大肠杆菌大小的1/6000,病毒的1/300)的反渗透膜(RO膜),使较高浓度的水变为低浓度水,同时将工业污染物、重金属、细菌、病毒等大量混入水中的杂质全部隔离，从而达到饮用规定的理化指标及卫生标准,产出至清至纯的水,是人体及时补充优质水份的最佳选择.由于RO反渗透技术生产的水纯净度是目前人类掌握的一切制水技术中最高的,洁净度几乎达到100%,所以人们称这种产水机器为反渗透纯净水机。
 反渗透设备应用膜分离技术，能有效地去除水中的带电离子、无机物、胶体微粒、细菌及有机物质等。是高纯水制备、苦咸水脱盐和废水处理工艺中的最佳设备。
优点
◇可以从海水或苦咸水中提取淡水。
◇容易去除有机物、细菌和胶体及溶于水中的其他杂质，获得高纯度的水。
 ◇由于反渗透过程是一个物理过程，没有相变，因而节能。
◇操作简单，易实现自动化，节省劳力。
◇结构紧凑，占地小，从而降低费用。
◇作为一种浓缩方法，能回收溶解在溶液中有价值的成分。
Pure water
Industrial boiler water treatment method for many general can be divided into the pot of water treatment and boiler water treatment. Boiler water treatment is mainly water softening, before the water into the boiler, through physical, chemical and electrochemical methods to remove the watercalcium, magnesium hardness salt and oxygen, prevent boiler scale and corrosion. Boiler water treatment is to the boiler (or to the water tank, water supply pipeline in chemical agent to vote) to prevent or mitigate fouling and corrosion of the boiler.
Reverse osmosis equipment is the raw water through a fine filter, the granular activated carbonfilter, compressed activated carbon filter, and then through the pump pressure, the use of apertureis 1/10000 mu m (equivalent to the size of the Escherichia coli 1/6000, viral 1/300) reverse osmosis membrane (RO membrane), the relatively high concentration of water into a low the concentration of water, at the same time the industrial pollutants and heavy metal impurities, bacteria, viruses and other large mixed with water so as to achieve the full isolation, physicochemical and sanitary standard of drinking regulations, output to clear to the pure water, is the best choice for the human body timely replenishment of high-quality water. Because the RO reverse osmosis water cleannessproduction technology is the highest all water preparation technology of current human master cleanliness of almost 100%, so people call this water producing machine , for reverse osmosis purewater machine.
Reverse osmosis membrane separation technology, can effectively remove water charged ions,inorganic, colloidal particles, bacteria and organic substances. Is the best equipment for the preparation of highly pure water, desalination of brackish water and wastewater treatment process in.
Advantage
◇To extract fresh water from sea water or brackish water.
◇ Easy removal of organic substances, bacteria and colloidal and soluble in water and other impurities, obtain high purity water.
◇ Because of the reverse osmosis process is a physical process, no phase change, thereby saving energy
◇ Simple operation, easy realization of automation, labor saving.
◇ Compact structure, small occupation of land, thereby reducing costs.
◇As a kind of method of concentration, can recover the valuable dissolved in the solution |
