The West Basin Water Recycling plant (California; USA) was built to increase the region's water resource availability. The plant influent is produced at Los Angeles Hyperion wastewater treatment plant and is treated through two parallel treatment processes depending on the end use: (1) Title 22 water for industrial and urban use, and (2) barrier treatment for groundwater recharge. A new methodology was applied to monitor the fate of base neutral compounds in the water barrier treatment train. The methodology included large sample volumes coupled with integrated chromatographic analysis (ICA). Data indicated a 25% increase in concentration of base neutral compounds after RO pretreatment, followed by a 70% removal efficiency after RO. The increase in concentration after RO pretreatment appears to be linked to the use of lime clarification.
西盆地水回收厂（美国加利福尼亚州）的建成是为了增加该地区的水资源供应。该厂的进水来自洛杉矶海波龙污水处理厂，根据最终用途通过两个平行的处理工艺进行处理：（1）用于工业和城市用途的22号标准水，以及（2）用于地下水回灌的屏障处理。一种新的方法被应用于监测水屏障处理流程中碱性中性化合物的去向。该方法包括大量的样品体积以及综合色谱分析（ICA）。数据表明，反渗透预处理后碱性中性化合物的浓度增加了25%，随后反渗透后的去除效率为70%。反渗透预处理后浓度的增加似乎与石灰澄清的使用有关。
