由于需要对储存在好莱坞水库中的成品水进行额外处理，洛杉矶水电局评估了微滤（MF）的功效，以满足地表水处理规则的要求。该评估包括一项中试，以评估MF工艺，并确定设计参数（化学清洗的通量和频率）。成品水浊度和颗粒去除与测试水中的通量无关。这一发现使公用事业公司能够以比加州法规目前允许的67 gfd（114-L/m2/h）流量高50%的流量运行MF系统。膜阻力用于评估系统在温度、流量和压力变化的操作条件下的性能。预计设计流量为67 gfd（114 L/m2/h）的过滤器在化学清洗前运行两个月（即66天）以上。 通过更频繁地对MF膜进行化学清洗，可以接受80-100 gfd（136-170 L/m2/h）的更高通量。包括22个参考文献、表格和图表。

Faced with the need for additional treatment of its finished water stored in the Hollywood Reservoirs, the Los Angeles Department of Water and Power evaluated the efficacy of microfiltration (MF) to meet the requirements of the Surface Water Treatment Rule. This evaluation included a pilot test to assess the MF process and to define the design parameters (flux and frequency of chemical cleaning). Finished water turbidity and particle removal were independent of flux in the tested water. This finding allows the utility to operate the MF system at a flux as much as 50 percent higher than the 67-gfd (114-L/m2/h) flux currently allowed by California regulations. Membrane resistance was used to evaluate the system performance under variable operating conditions of temperature, flux, and pressure. A design flux of 67 gfd (114 L/m2/h) was projected to yield more than two months (i.e., 66 days) of filter run before chemical cleaning. A higher flux of 80-100 gfd (136-170 L/m2/h) was acceptable with more frequent chemical cleaning of the MF membranes. Includes 22 references, tables, figures.
