本powerpoint演示文稿首先简要概述了使用点（POU）设备和NSF/ANSI 53，NSF/ANSI 53是一个公认的标准，涵盖 特别是对POU设备的健康影响，可能包括铅（Pb）去除。项目目标包括:比较溶解铅和颗粒铅的去除 不同类型POU装置的效率（倾注式 水槽下安装有水龙头的水罐）； 通过倒罐（Pb、， 铜、镍、铬）； 通过罐式过滤器进行银浸出评估； 在现场测量POU过滤器对水质参数的影响 污水； 评估过滤器硝化作用对环境的影响 过滤器中铅颗粒的溶解；和 评估under的效率和适用性- 水槽 用于溶解和颗粒铅的POU装置 大型建筑的挑战。研究方法包括以下5个实验: 通过倒罐进行金属去除试验，以及 给水中不添加铅、铜、铬； 经过测试的灌入式水罐，用于去除Pb_{部分，以及 测量了过滤器对NH3-N和pH的影响； 与（I）相同，但在实际家庭中使用时间和时间 给水中不添加任何金属； 比较了3种类型的铅diss和铅part的去除情况 使用领航员的POU（3个水罐，2个安装在水龙头上的装置， 2）并评估了 POU过滤器对出水水质参数的影响；和 测试适用性（成本）- 水槽下的效率 大型建筑中的POU设备呈现出高水平的 Pbdiss和Pbpart。包括数字。}

This powerpoint presentation begins by providing a brief overview of point-of-use (POU) devices and NSF/ANSI 53, a recognized standard that covers health effects specifically for POU devices, and can include lead (Pb) removal. Project objectives included the following: compare dissolved and particulate Pb removal efficiency for diverse types of POU devices (pour-through pitchers, tap-mounted, under-the-sink); evaluate metal removal by pour-through pitchers (Pb, Cu, Ni, Cr); assess Ag leaching by pour-through pitcher filters; measure the effect of POU filters on water quality parameters at the effluent; evaluate the effect of filter nitrification on the dissolution of Pb particles trapped in the filter; and, evaluate the efficiency and applicability of under-the-sink POU devices to solve dissolved and particulate Pb challenges in large buildings. Study methodology included the following 5 experiments: tested metal removal by pour-through pitchers, with and without additions of Pb, Cu and Cr in feed water; tested pour-through pitchers for Pb_part removal, and measured the effect of filters on NH₃-N and pH; same as (I) but in real household using time and without any metal addition in feed water; compared Pb_diss and Pb_part removal for 3 types of POU using a pilot (3 pitchers, 2 tap-mounted devices, 2 under-the-sink devices), and evaluated the effect of POU filters on water quality parameters at the effluent; and, tested the applicability (cost-efficiency) of under-the-sink POU devices in a large building presenting high levels of Pb_diss and Pb_part.
