摘要在加州中央谷的Fabbri农场井水源（TDS：1，304 ppm; SiO2：57 ppm）中，在极端二氧化硅过饱和（930 ppm）条件下，使用闭路脱盐（CCD）试验装置，在pH 5.5和阻垢剂（FLOCON-260）存在下，对回收率高达93.8%的水进行脱盐。在本研究中描述了Fabbri源在17.2和19.6 lmh 7.2下的实验性试验，提供了在17.2 lmh下的92.8%回收率的延长8小时试验的完整在线数据，其中连续顺序压力变化为6-14 bar，平均渗透物的电导率（EC（230 μS/cm）和括号中引用的盐水（23，450 μS/cm），比能耗为0.918 kWh/m3，高压泵效率为55%。对扩展试验和所有其他试验期间的连续连续在线数据的分析表明，模块压差不变，最大和最小施加压力、渗透率EC和最大压力的变化较小。
AbstractThe Fabbri farm well-water source (TDS: 1,304 ppm; SiO2: 57 ppm) in the California Central Valley was desalinated with up to 93.8% recovery under extreme silica supersaturation (930 ppm) conditions using a closed-circuit desalination (CCD) pilot with a single module (8″) of three elements at pH 5.5 in the presence of an antiscalant (FLOCON-260). Experimental trials of the Fabbri source at 17.2 and at 19.6 lmh 7.2 are described in this study with complete online data provided for an extended 8-h trial at 17.2 lmh of 92.8% recovery with consecutive sequential pressure variation of 6–14 bar and electric conductivity (EC) of average permeates (230 μS/cm) and of brine (23,450 μS/cm) cited in parentheses and specific energy consumption of 0.918 kWh/m3 with high-pressure pump efficiency of 55%. Analysis of the consecutive sequential online data during the extended and all other trials revealed unchanged module pressure difference and minor variations of maximum and minimum applied pressures, EC of permea...
