工業鍋爐水處理方法很多總體可分為鍋外水處理和鍋內水處理。鍋外水處理主要是水的軟化,即在水進入鍋爐之前,通過物理的、化學的及電化學的方法除去水中的鈣、鎂硬度鹽和氧氣,防止鍋爐結垢和腐蝕。鍋內水處理就是往鍋爐 (或給水箱、給水管道)內投加藥劑達到防止或減輕鍋爐結垢和腐蝕的目的。
反滲透設備是將原水經過精細過濾器、顆粒活性碳過濾器、壓縮活性碳過濾器等,再通過泵加壓,利用孔徑為1/10000μm(相當于大腸桿菌大小的1/6000,病毒的1/300)的反滲透膜(RO膜),使較高濃度的水變為低濃度水,同時將工業污染物、重金屬、細菌、病毒等大量混入水中的雜質全部隔離,從而達到飲用規定的理化指標及衛生標準,產出至清至純的水,是人體及時補充優質水份的最佳選擇.由于RO反滲透技術生產的水純凈度是目前人類掌握的一切制水技術中最高的,潔凈度幾乎達到100%,所以人們稱這種產水機器為反滲透純凈水機。
反滲透設備應用膜分離技術,能有效地去除水中的帶電離子、無機物、膠體微粒、細菌及有機物質等。是高純水制備、苦咸水脫鹽和廢水處理工藝中的最佳設備。
優點
◇可以從海水或苦咸水中提取淡水。
◇容易去除有機物、細菌和膠體及溶于水中的其他雜質,獲得高純度的水。
◇由于反滲透過程是一個物理過程,沒有相變,因而節能。
◇操作簡單,易實現自動化,節省勞力。
◇結構緊湊,占地小,從而降低費用。
◇作為一種濃縮方法,能回收溶解在溶液中有價值的成分。
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 |
