On March 23, 2012, China's energy environment of science and technology association of professional committee of the membrane and water treatment technology, the first held a meeting in the city of zhengzhou in henan province. By China association of energy and environment technology membrane and water treatment technology, director of professional committee of the golden host, China's energy and environmental science and technology association, director of the secretary-general Zhu Hongyu yong-feng lu to visit the scene of the meeting.
the main business of this meeting is: discuss changes of the Chinese energy environmental science and technology association of professional committee of the membrane and water treatment technology, the articles of association '( Draft) ； Submit to branch of 2012 annual work report.
branch director comrade golden thought, energy and environment science and technology association, China is the purpose of perfecting the membrane and water treatment technology branch association of widening the needs of the architecture, but also from countries in the field of environmental protection, energy saving and emission reduction in the practice of China's industrial enterprises try to a service. Branch of the construction and development, aiming to create a push industrial water treatment technology promotion platform, supported by expert team in the field of environmental protection, water treatment application terminal as demand for the carrier, by the user application technology improvement to lower production costs and industrial enterprise efficiency purpose.

Membrane separation technology is the use of membrane for the selection of various components in the mixture through the performance to the product of the separation, purification and concentration of new separation technology, membrane separation process is a kind of no phase change, lower energy consumption physical separation process, with high efficiency, energy saving, no pollution, easy operation, wide application characteristics and foreign called the 21st century the most promising one of the top ten new and high technology.


threonine is a kind of essential amino acids, mainly used in pharmaceutical, chemical reagents, food fortifier, feed additive, etc. Threonine a mother liquor production process of centrifugal separation, high content of inorganic salt, salt by using ion exchange resin in addition to the original process, from the liquid by activated carbon decoloring, removing part of the protein, crude products. Traditional process needs to consume large amounts of acid and alkali, resin regeneration cycle is short, easy to loss, waste acid alkali emissions pollution of the environment, decoloring link activated carbon is used up big, virtually raised the enterprise production operation cost, environmental protection pressure.


in fujian threonine production process, adopts special 'nanofiltration membrane electrodialysis +' as a centrifugal mother liquor of desalination and decoloring purification process.


threonine centrifugal mother liquor after first 0 at a time. 5% activated carbon and microfiltration process, with a yield of 98% or more hollow microfiltration membrane system; After processing of centrifugal mother liquor adopts special electrodialysis removing most of the inorganic salt, initial conductivity, 100, 000 ~ 130, 000 mu s/cm to conductivity 14 ~ 16 000 000 mu s/cm, removal rate of 88%, threonine loss rate of 10% or less; Electrodialysis desalination liquid decolorization by nanofiltration system purification, nanofiltration membrane system including pretreatment and decoloring purification system two parts. Pre filtration system to remove electrodialysis desalination possible existence of solid particles in liquid, suspended solids and other mechanical impurities. Decolorizing purification system with high separation efficiency, about 700 ~ 800 intercept molecular weight of nanofiltration membrane separation material, driven by the pressure water and threonine through nanofiltration membrane to enter through the liquid side, into the next production working procedure, and intercept protein, most of the pigment and macromolecular organic matter, realize the desalted liquid in the purification, threonine yield ( Including intercept and through the clear liquid) ≥98%。


use a variety of membrane technology to deal with a centrifugal mother liquor threonine, simplify the production technology, improve product quality, in order to realize the economic benefit and environment benefit unifies.


the hydroxy phenyl glycine is a kind of pharmaceutical intermediates, the production process can produce high salt content. Processing technology of mother liquor was after ion exchange resin in addition to salt, again by active carbon decoloring, finally with the filtrate into normal refining process. Mother liquid to use after a certain number of times, impurity, affect the product quality, then you need to mother liquor. The disadvantages of previous process lies in the acid and alkali consumption of large, resin wastage is bigger, lead to the production cost is higher, at the same time because of the emissions of acid and alkali, make the heavier pollution to the environment.


by nearly a month of pilot, set up 60 m3 / d of hydroxy phenyl glycine centrifugal mother liquor special electrodialysis desalination system. Running the results are shown in table 1


in addition, the membrane technology is applied to the process for production of glutamine, arginine, etc, such as the membrane electrodialysis desalination technology Ghana membrane filter decoloring after purification, arginine mother liquor of pervious to light can reach 80% ~ 92. 7%; In glutamine slurry process, membrane electrodialysis desalination rate ( By conductivity meter) Up to 90%.

In many fields, water filtration is a very important link, so the role of water filter is particularly important. So, what is the principle of the water filter element? The Lvyuan water filter element manufacturer introduces the principle of the water filter element in detail. 1. The filtration principle and operation method of water treatment. The quality of raw water is very complicated, and a series of filtration steps are needed to get the required water quality, so the filtration process of water treatment is necessary. Filtration is the use of a porous medium to separate the suspension. When working, under the action of external force, the liquid in the suspension flows out through the pores of the medium, and the solid particles are intercepted, thereby realizing separation. Generally, the suspension to be filtered is called the filter slurry; the porous medium used is called the filter medium; the liquid passing through the pores of the medium is called the filtrate; the retained solid is called the filter cake or filter residue. 2. The driving force of the filtration operation is the pressure difference between the upstream and downstream sides of the filter medium. There are several ways to generate the pressure difference: ①Using the pressure head of the filter slurry; ②Pressing on the surface of the filter slurry; ③In the filter medium Vacuum on the downstream side; ④Using inertial centrifugal force. Filtration operations can be divided into two categories according to the principle of action: 1. Sieve analysis filtration: The pore size of the filter medium is smaller than the diameter of the solid particles, and the solid particles are removed from the suspension by the sieve analysis. In the initial stage of sieve filtration, fine particles flow out, and the filtrate is relatively turbid. With the formation and thickening of the cake layer, the filtrate gradually becomes clear. Due to the gradual blockage of the sieve holes, the filtration rate is in a decreasing trend. During the filtration process, when the filter cake layer is formed, the sieving effect is produced by the cake layer, and the filter medium loses the sieving effect and only plays the role of supporting the cake layer, which is called cake layer filtration. 2. Adsorption filtration: The mesh of the filter medium is larger than the diameter of the solid particles, and the solid particles are absorbed by the surface of the medium after entering the pores of the filter medium. In actual production, sieve analysis and adsorption work simultaneously, and the adsorption filter medium retains larger particles; the sieve filter medium cake layer can adsorb smaller particles.
