Investigation of a new, low-cost, safe and highly efficient water disinfection alternative to conventional methods has prime importance. This study aims to develop silver nanowire decorated glass fiber (AgNW-GF) filters for the removal of E. coli from water. This is the first study to fabricate a novel AgNW-GF filter and to investigate its use for point-of-use (POU) water disinfection. To this purpose, the effects of flow rate, AgNW loading and influent E. coli concentration on the removal efficiency of E. coli and Ag release from AgNW-GF filters were investigated. Effect of filtrate volume on Ag release was also analyzed. Disk diffusion tests revealed that AgNW-GF filters with different AgNW loadings had antibacterial effects against E. coli at a concentration range of 10³ – 10⁸ CFU/ml. Flow tests were conducted in order to investigate optimal conditions at which AgNW-GF filters achieved the highest E. coli removal efficiency. Optimal flow rate, AgNW loading and influent E. coli concentration were found out as 1 ml/min, 9.9 mg/g, and 10³ CFU/ml, respectively. The highest removal efficiency was obtained as 2.12 log after two-stage serial filtration under optimal conditions. The released Ag amounts were all below the limit value of 100 ppb for potable water. Under determined optimal conditions, AgNW-GF filter was found as a promising alternative for POU water disinfection method to be used in contaminated natural water (<10³ CFU/ml).

研究一种替代传统方法的低成本，安全，高效的新型水消毒方法至关重要。这项研究旨在开发银纳米线装饰的玻璃纤维（AgNW-GF）过滤器，用于从水中去除大肠杆菌。这是首次制造新型AgNW-GF过滤器并研究其用于使用点（POU）水消毒的研究。为此，流率，的AgNW装载和进水的效果大肠杆菌浓度上的去除效率的大肠杆菌，并从的AgNW-GF过滤器的Ag释放进行了调查。还分析了滤液体积对Ag释放的影响。圆盘扩散测试表明，具有不同AgNW负载量的AgNW-GF过滤器对大肠杆菌具有抗菌作用浓度范围为10 ³ – 10 ⁸ CFU / ml。为了研究AgNW-GF过滤器达到最高大肠杆菌去除效率的最佳条件，进行了流量测试。最佳流速，AgNW载量和进水大肠杆菌浓度分别为1 ml / min，9.9 mg / g和10 ³ CFU / ml。在最佳条件下进行两阶段串联过滤后，去除效率最高，为2.12 log。释放的银量都低于饮用水的极限值100 ppb。在确定的最佳条件下，发现AgNW-GF过滤器是用于受污染的天然水中（<10 ³ CFU /毫升）。
