Reverse Osmosis Technology Conceived The Study, Kunming Cigarette Boiler Water Treatment

Membrane separation technology is a modern efficient new technology. Compared with traditional separation techniques, it has several prominent advantages, including high separation efficiency, low energy consumption (no phase transition), small occupied area , simple separation process (easy to control and magnify), convenient operation, no pollution, easy integration with other technologies. The researches and applications of membrane separation technology has extremely closed relation to energy saving, environmental protection, water resources development, utilization and regeneration. Under the condition that the shortage of energy and water resources and the pollution of water and environment are getting serious in the world, the research of membrane separation science and technology, which is becoming an important component of the strategy to the sustainable economic development, has been paid great worldwide attention. Meanwhile, the membrane technology is a high-tech to reconstruct traditional industries and promote technological advancement of the related industries. Over the last 10 years, the reverse osmosis technology has been highly developed in china, which has been widely used in oil, power industry, metallurgy, chemical industry, electronics, pharmacy, food and other industries. Furthermore, the reverse osmosis technology has become the mainstream technique of sea water desalination and sewage treatment, and has begun to enter the water supply field in cities. Nowadays, an industrial chain whose core is the reverse osmosis technology has been formed in China, which is consist of the related product development, production, sale, installation, operation and service, and has formed a high-growth emerging water treatment industry of membrane techniques.The paper discussed the basic knowledge and the basic concepts of the membrane technology, then elaborates the basic design patterns and the pre-process techniques of the membrane system, as well as the pollution and clean techniques of membrane. On this basis, the paper focused on the reverse osmosis technique in membrane separation technology. In order to resolve the problems of the water treatment equipments of the boiler used in Kunming Cigarette Factory, we proposed to install a reverse osmosis equipment before the three-tower-flow bed to remove the disadvantages of the original water treatment equipments. Furthermore, we designed a reverse osmosis system assorting with the original equipments, and forecasted the possible results owing to the installation of the reverse osmosis system from a technical and economic point of view. Finally, a summary of the research of this paper and the direction for the future work are given.
