摘要
胶体污染是膜元件污堵的主要原因之一。它不仅严重影响膜元件的使用性能:如产水量的急剧下降、系统压差的增加及脱盐率的降低等等,而且还会降低膜元件的使用寿命,以及给用户带来生产上的诸多不便。为此,有效预防膜元件的胶体污染对反渗透系统的正常运行有很大的益处。
The one of the main cause of membrane parts pollution and plugging is due to colloid pollution. Performance of membrane parts will be affected seriously such as water yield rapid fall, system pressure difference increasing and salt exclusion rate decreased etc. Also the lifetime of membrane parts will be decreased. For this reason, to take effective measure for prevented colloid pollution of membrane parts will be paid more attention for reverse osmosis system operation in good condition.
