Moreover , the membranes employed in electrodialysis are of two types .
而且，电渗析所采用的过滤膜是两种不同类型的。
The disadvantage is that reverse electrodialysis produces direct current , whereas the world runs mostly on alternating current .
不足处是反向电渗析产生的是直流电，而世界上主要使用交流电。
Since 2001 a dutch company called kema has been working on an osmotic power plant that uses a different approach , reverse electrodialysis .
一个名叫kema的荷兰公司从2001年就开始研究渗透能电厂，但采取的是另外一种方式反向电渗析。
The fuel cell gives the energy boost for the reverse electrodialysis system allowing the process to operate with fewer membranes and making the system cheaper to produce .
After the determination of the limiting current density , the influences of different flow rate and different concentration on the desalting rate and the recovery of amino acid in the electrodialysis desolation of the amino acid solution were measured , the best operation parameters were determined .
