Attention:
1. The ultra-filtration must be worked under the set pressure and temperature, if not it would be broken up with hyper pressure and the over temperature.
2. Because be membrane interception substance in the membrane surface deposition, the ultra-filtration rate and interception will be decline. So the ultra-filtration device should be cleaned by isobaric pressure flushing,back washing and chemical cleaning.
3.Due to process solution on membrane fouling at different levels, the actual filtering solution ultra-filtration rate much lower than the factory calibration rate, therefore ultra filtration for special solution processing membrane design ultra-filtration rate should be determined according to the test.
4. When operating must maintain steady lifting pressure, sudden lift pressure makes resin sealing head deciduous or fiber breakage.
During the ultra-filtration work process, the separation of substances and other impurities will gradually deposited on the membrane surface, causing pollution and congestion on the membrane, the ultra-filtration membrane cleaning is indispensable ultra-filtration steps, membrane cleaning is to extend the effective an important means of membrane life. Methods of membrane cleaning include chemical cleaning and physical cleaning.
Detailed Product Description
Ultra-filtration is a pressure-driven membrane separation technology. The aim of the technology is to separate macromolecules and small molecules whose membrane is between 20-1000A°.
In the ultra-filtration process, the water depth is driven by hydraulic pressure and flows through the membrane surface. The ultra-filtration process is a dynamic filtration; separation is accomplished in the mobilization state. Solute in the membrane surface is only a limited deposition, the ultra-filtration rate to a certain degree of attenuation tends to balance , and can be restored by cleaning.
Advantages and disadvantages:
Ultra-filtration technology is easily to be supplied and the cost is low. Meanwhile, it doesn't need any chemical reagents. As a result, the temperature and the PH value of the material can't be changed. In the preparation of biological macromolecules, the UF is mainly used for the desalination of biological macromolecules, dehydration and enrichment. Ultra filtration also has certain limitations. It can not be directly changed into dry powder formulation. For the protein solution, generally we can only get 10-15% concentrations.
