【展商资讯】德兰梅尔:汇总反渗透膜在水处理中的广泛应用

反渗透是一种以压力为推动力的膜分离过程在使用中为产生反渗透压需用水泵给含盐水溶液或废水施加压力以克服自然渗透压及膜的阻力使水透过反渗透膜,将水中溶解盐或污染杂质阻止在反渗透膜的另一侧。

RO is a pressure-driven membrane separation process in use to produce RO pressure need to use a pump to put pressure on saline solution or wastewater to overcome the natural osmotic pressure and membrane resistance so that water through the RO membrane, the water dissolved salt or pollution impurities to prevent the other side of the RO membrane.

  反渗透膜是目前各种膜分离技术中在国内发展成功并且普及范围广的一种膜技术,它于80年代初被应用于制备电子行业超纯水及饮料行业饮用水,并于90年代初在水处理方面得到广泛应用。目前,反渗透膜技术已在海水淡化、城市污水处理、工业废水处理等各种水处理方面得到普及,并且该技术还具有高效、清洁、绿色、无污染、适用范围广等优点,是当今世界水处理技术之一。

RO membrane is a kind of membrane separation technology developed successfully and widely in China. It was used in the preparation of ultrapure water in the electronics industry and drinking water in the beverage industry in the early 1980s, and was widely used in water treatment in the early 1990s. At present, RO membrane technology has been popularized in seawater desalination, municipal sewage treatment, industrial wastewater treatment and other water treatment, and the technology also has the advantages of high efficiency, clean, green, pollution-free, wide range of application, is one of the world’s water treatment technology.

反渗透膜在水处理中的应用

Application of RO membrane in water treatment

(1)在水处理方面的常规应用
(1)Routine applications in water treatment

  水是人们赖以生存和进行生产活动必不可少的物质条件。由于淡水资源日益缺乏,世界上反渗透水处理装置的能力已达到每天数百万吨。

 Water is an essential material condition for people to survive and produce. Due to the increasing scarcity of fresh water resources, the capacity of RO water treatment units in the world has reached millions of tons per day.

(2)在城市污水方面的应用

  (2) Applications in municipal sewage

目前,反渗透膜在城市污水深度处理方面的应用尤其是污水处理厂二级出水回用及中水回用等,已受到高度重视。

At present, the application of RO membrane in the advanced treatment of municipal sewage, especially the secondary effluent reuse and reclaimed water reuse in sewage treatment plants, has received high attention.

(3)在重金属废水处理方面的应用

(3)Applications in heavy metal wastewater treatment

含重金属离子废水的常规处理方法都只是一种污染转移,即将废水中溶解的重金属转化成沉淀或更加易于处理的形式,其处置常常是进行填埋,而重金属对地下水和地表水环境造成二次污染的危害依然长期存在。

The conventional treatment methods of wastewater containing heavy metal ions are only a pollution transfer, that is, the dissolved heavy metals in the wastewater are converted into precipitation or a more easily treated form, which is often disposed of by landfill. However, the harm of secondary pollution caused by heavy metals to the groundwater and surface water environment still exists for a long time.

(4)在含油废水方面的应用
(4)Applications in oil-bearing wastewater

  含油废水是一种量大面广的工业废水,若直接排入水体,会在水体表层产生油膜阻碍氧气溶入水中从而致使水中缺氧、生物死亡、发出恶臭,严重污染生态环境,利用膜处理技术,油田采出水处理到锅炉用水水质,于是处理后的水回用于电站锅炉给水。

Oily wastewater is a kind of industrial wastewater quantity bedding face is wide, if directly discharged into water body, can produce the oil film on the water surface to hinder the oxygen dissolved in the water killed the water of oxygen, biological and stench, polluted the ecological environment, using the membrane treatment technology, oil field produced water treatment to boiler water quality, water for power plant boiler feed water and treated water back.

  德兰梅尔凝聚多年膜产品研发和应用经验,根据产品在不同行业实际应用反馈数据,不断迭代升级产品性能,为用户提供成熟的膜产品,始终致力于为用户提供水处理及水处理流体分离在内的膜集成技术整体解决方案。

Based on many years of experience in membrane product development and application, Delemil constantly iterates and upgrades the product performance according to the feedback data of the actual application of products in different industries, provides mature membrane products for users, and is always committed to providing users with the overall solution of membrane integration technology including water treatment and water treatment fluid separation.

  德兰梅尔反渗透膜采用OTM一次成膜技术,增加了膜层的厚度,同时避免了由于涂装不均匀导致的膜元件脱盐率不稳定的问题,在海水淡化、工业纯水、电子超级水、中水回用、生物制药、食品行业分离浓缩等领域都发挥着重要作用。

Delemil RO membrane use OTM membrane technology, increased the membrane layer thickness, at the same time avoid the membrane element desalination rate due to uneven coating of unstable problem, in seawater desalination, industrial pure water, electronic super water, water reuse, biological pharmacy, food industry areas such as separation, enrichment have played an important role.
