Abstract

This paperstudied the impact of the addition of pulse electric-filed infiltration process as a disinfectant function by designing, constructing, and operating a new laboratory-scale water filtration/disinfection technique. The Disinfectant Filter Unit (DFU) demonstrated several benefits in terms of efficiency, cost-effectiveness, and the ease of application, without the use of any chemical additive. This system contains a rapid sand filter and silver mesh electrode with a low pulse voltage for the water treatment. The parametric effects of the DFU performance, such as alternating current pulse frequency, the number of and the connection method of mesh electrode pairs, the voltage applied with electrical conductivity and electric field direction were studied. The exanimation of the cell wall morphology of Escherichia coli cells under transmission electron microscopy showed the change and damage before and after treatment. The optimum conditions were found to be 25 V, 0.5 Hz, and 2 pair mesh of electrode connection in an opposite direction of flow for 93% turbidity removal and 99.6% microorganisms removal.
