Characteristics of particle and membrane pore sizes in the performance of water recovery from a fine carbon loaded wastewater using a vibration membrane system

摘要

In dealing with the fine carbon loaded wastewater from a TV picture tube plant,the technique of vibration membrane was proven to be a more effective means than the conventional coagulation and settlement method.The present work is to look into the characteristics of the carbon particle sizes and the membrane pore sizes in the performance of the vibration membrane.The parameters taken into consideration in this work include membrane types,particle sizes,particles concentration,trans-membrane pressure,vibration amplitude and feed temperature.The studies showed that one could achieve a higher permeate flux and less frequent back wash through a suitable match of particle size and membrane type.
