为了评估该县反渗透设施（NDF）在无硫酸的情况下对地下水进行反渗透处理（NDF）的性能，我们在纽基斯达县规模上对反渗透设施（NDF）的反渗透性能进行了比较。测试使用定制的反渗透试验装置进行 设计用于同时进行两个单独的测试 利用两列平行排列。两个完全相同的飞行员 火车和主厂房接收的原水具有相同的水质 特点。每列列车均配备专用阻垢剂 和酸计量泵。 两级阵列 第一阶段为ESPA1膜，第二阶段为ESPA2膜 第二阶段复制当前在服务器上使用的两阶段阵列 全面NDF。

The objectives of this project were to compare the performance of various anti-scalants for the treatment of brackish groundwater at Alameda County Water District's Newark Desalination Facility (NDF), and to evaluate membrane performance with regard to scale formation without the addition of sulfuric acid to the reverse osmosis (RO) feed water at the NDF. Testing was conducted using a custom made RO pilot unit designed to carry out two separate tests simultaneously by utilizing a two-train parallel arrangement. The two identical pilot trains and the main plant received raw water with identical characteristics. Each train is equipped with dedicated antiscalant and acid metering pumps. The two stage array with ESPA1 membranes in stage one and ESPA2 membranes in stage two replicates the two-stage array currently in use at the full-scale NDF.
