这项工作报告了圣莫尼卡市阿卡迪亚水处理厂Rotec的反流反渗透(FRRO)的中试数据分析。结果表明,周期性的块旋转和进料流反转平衡了盐和污垢负荷,减缓了结垢形成,在典型的CIP间隔30天内实现了90%的回收率。当膜被污染时,比通量下降,比压降增加。尽管如此,最后阶段的压力通常不超过200磅/平方英寸。这一成功的试点导致了美国第一个FRRO全尺寸市政设施的设计和调试。
This work reports piloting data analysis of ROTEC's flow reversal RO (FRRO) at City of Santa Monica's Arcadia Water Treatment Plant. It is shown that periodic block rotation and feed flow reversal balance salt and foulant load and mitigate scaling formation, enabling a 90 % recovery with a typical CIP interval over 30 days. As membrane fouls, there is a decline in the specific flux and an increase in the specific pressure drop. Nevertheless, the last stage pressure is usually no more than 200 psi. The successful pilot led to the design and commissioning of the first FRRO full-scale municipal installation in the United States.
