Olivenhain水处理厂的这项研究的目的是确定在原水次氯酸钠注入点注入渗透（过滤水）泵的化学品的t10，其标称运行容量为2500万加仑/天（MGD）。进行了示踪研究，以验证通过膜池的滞留时间。此处使用的测试方法基于HACH DR/2010分光光度计手册中建议的氨纶方法。 使用HACH分光光度计（HACH DR/2010）分析真空密封氟化物试剂Accu-Vac安瓿中收集的水样。安瓿由分光光度计在580纳米的波长下读取。理论数据表明，该系统的投加时间等于理论停留时间t10值的三倍。为了模拟理论浓度曲线，设计了一种类似于曲线形状并基于“t10的3倍”值的采样制度。 包括数字。

The purpose of this study at the Olivenhain Water Treatment Plant was to determine the t10, at the nominal operating capacity of 25 million gallons per day (MGD), of a chemical injected at the raw water sodium hypochlorite injection point to the permeate (filtered water) pumps. A tracer study was performed to verify the detention time through the membrane basins. The testing method used here was based on the SPANDS method as suggested in the HACH DR/2010 Spectrophotometer Handbook. A HACH spectrophotometer (HACH DR/2010) was used to analyze water samples that were collected in vacuum-sealed Fluoride Reagent Accu Vac ampuls. The ampuls were read by the spectrophotometer at a wavelength of 580 nanometers. Theoretical data suggest that the system be dosed for a period of time equal to three times the theoretical residence time, t10, value. In order to mimic the theoretical concentration curve, a sampling regime similar to the shape of the curve and based on the "3 times the t10" value was devised. Includes figures.
