【Abstract】 A method of calculating the optimum time to replace the membrane after running for one year or at later stage of running was introduced.The cost of replacing membrane and the increase of electricity cost per year were calculated.Based on the practical running conditions of membrane,the replacement of membrane should be also considered although the economical time wasnt up.Points for attention were raised if replacement of membrane in advance was necessary.更多还原
