水處理設(shè)備
多種介質(zhì)過濾器
多介質(zhì)過濾罐大多填充石英砂、無煙煤和錳砂等濾料。其作用主要是降低水濁度，并且可以去除水中的大量細(xì)菌、病毒、有機(jī)物等。從而為后續(xù)的消毒工序創(chuàng)造了有利條件。錳砂對鐵、錳的去除。
活性碳過濾罐
活性炭具有大量的微孔和巨大的比表面積，具有的物理吸附能力。能夠十分有效的吸附水中雜質(zhì)，尤其是有機(jī)物和微生物?；钚蕴勘砻嫘纬傻暮醮呋趸突瘜W(xué)吸附的功能，可以去除一部分水中的金屬離子?；钚蕴繉λ猩写娴挠嗦扔械奈阶饔?，以保護(hù)下游的不銹鋼設(shè)備及管道表面和滿足后序水處理單元的入水要求。
自動(dòng)反沖、再生軟化罐
軟化罐內(nèi)填充鈉型陽離子交換樹脂?？送ㄟ^樹脂的離子交換反應(yīng)，降低水的硬度，防止鈣、鎂離子與碳酸根、硫酸根離子結(jié)合，在后序水處理設(shè)備或管道中結(jié)垢。
精密過濾器
精密過濾器又稱保安過濾器，過濾精度一般為5μm。其作用在于截留一切粒徑大于5μm的物質(zhì)，以滿足反滲透的入水要求
。
RO反滲透
反滲透技術(shù)應(yīng)用的關(guān)鍵在于起除鹽作用的反滲透膜的性能。反滲透膜是一種只允許水分子通過而不允許溶質(zhì)透過的半通透膜。反滲透技術(shù)除了應(yīng)用反滲透和反滲透的原理外，還利用了膜的選擇吸附和針對有機(jī)物的篩分機(jī)理。反滲透膜的孔徑大多小于等于10×10-10m，其分離對象為溶液中處于離子范圍和分子量為幾百左右的有機(jī)物。它能濾除各種細(xì)菌，如最小的細(xì)菌之一綠膿桿菌（3000×10-10m），也能濾除各種病毒，如流感病毒（800×10-10m）,腦膜炎病毒（200×10-10m），還能濾除熱原（10~500×10-10m）。這是制藥用水十分關(guān)注的問題。
Water treatment equipment
A variety of media filters
Multimedia filter tank mostly filled with quartz sand, anthracite and manganese sａnd and other media. Its main function is to reduce water turbidity, and can remove a large number of bacteria in the water, viruses, organic matter and so on. Thus creating favorable conditions for the subsequent disinfection process. Manganese sａnd on iron, manganese removal effect is remarkable.
Activated carbon filter tank
Activated carbon has a large number of micropores and large specific surface area, with a strong physical adsorption capacity. Very effective adsorption of water impurities, especially organic matter and microorganisms. Activated carbon formed on the surface of the oxygen catalytic oxidation and chemisorption function, can remove part of the water in the metal ions. Activated carbon has a strong adsorption of residual chlorine in water to protect downstream stainless steel equipment and pipe surfaces and to meet water requirements for subsequent water treatment units.
Automatic recoil, regenerative softening tank
Softening tank filled with sodium cation exchange resin. Gram through the resin ion exchange reaction to reduce the hardness of water to prevent calcium and magnesium ions and carbonate, sulfate ions in the subsequent water treatment equipment or pipe scaling.
Precision filter
Precision filter, also known as security filter, filtration accuracy is generally 5μm. Its role is to retain all the particles larger than 5μm in diameter to meet the water requirements of reverse osmosis
.
RO reverse osmosis
The key to the application of reverse osmosis lies in the performance of the reverse osmosis membrane that functions as a desalting agent. A reverse osmosis membrane is a semi-permeable membrane that allows only water molecules to pass without allowing solute to pass through. Reverse osmosis technology in addition to the application of reverse osmosis and reverse osmosis principle, but also the use of membrane selective adsorption and screening mechanism for organic matter. Most of the reverse osmosis membrane pore size less than or equal to 10 × 10-10m, the object of separation for the solution in the ion range and molecular weight of about 100 organic matter. It can filter out various bacteria, such as Pseudomonas aeruginosa, one of the smallest bacteria (3000 × 10-10m), and can also filter out various viruses such as influenza virus (800 × 10-10m), meningitis virus (200 × 10-10m), but also can filter out pyrogen (10 ~ 500 × 10-10m). This is a matter of great concern to pharmaceutical water use.
