The biocidal efficiency of electrochemically activated solutions (ECAS) against isolated bacterial species from the water distribution network was analyzed. Predominant microbial consortia (identified using 16S rRNA gene sequencing as Aeromonas sp. Enterobacter sp. and Escherichia. coli) with a mean count of 1.15 × 10⁶ CFU/mL was inoculated in 100 L tap water in a prototype network to simulate real conditions. The physico-chemical quality of tap water of subsurface origin was assessed before experimentation. The contact times of 10 s, 10 min and 1 h were selected against the ECAS dosages of 1%, 5% and 10% (v/v), respectively. Each test organism showed an independent response at varying dosages. A 10% disinfectant dosage corresponding to a contact time of 1 h showed the highest Log reduction as 4.11 > 3.50 > 2.74 for Enterobacter sp. > E. coli > Aeromonas sp., respectively. The results revealed that due to varying physico-chemical composition and carbon content of test water, complete inhibition of test organism (1.15 × 10⁶ CFU/mL) was not achieved at 10% ECAS dosing for 1 h. The study concludes that adequate pretreatment could further enhance the removal efficacy and reduce the minimum inhibitory concentration of ECAS.

分析了电化学活化溶液（ECAS）对自来水分配网络中分离出的细菌的杀菌力。主要微生物聚生体（使用16S rRNA基因测序鉴定气单胞菌属肠杆菌属和埃希氏菌属。大肠杆菌），用1.15×10的平均计数⁶在原型网络中，将CFU / mL接种到100 L自来水中以模拟实际条件。实验前评估了地下来源的自来水的理化质量。分别针对1％，5％和10％（v / v）的ECAS剂量选择10 s，10 min和1 h的接触时间。每种测试生物在不同剂量下均显示出独立的反应。肠杆菌属细菌的10％消毒剂量（接触时间为1小时）显示出最高的Log降低值，即4.11> 3.50> 2.74 。>大肠杆菌>气单胞菌 ， 分别。结果表明，由于测试水的理化组成和碳含量不同，对测试生物的完全抑制（1.15×10 ⁶在10％ECAS剂量下1小时未达到CFU / mL）。研究得出结论，适当的预处理可以进一步提高去除效果并降低ECAS的最低抑菌浓度。
