Abstract:
Introduction
The conventional methods of water disinfection are chemical process, ozonation, UV radiation, membrane processes and etc. In recent years, electrolysis method has been considered that is a green process with high efficiency and not by-products. The aim of study is evaluation of efficiency of the electrolysis process with continuous flow in the disinfection of water contaminated with fecal coliform.
Materials And Methods
This study is a Descriptive - analytical study. The samples are prepared in three groups by adding domestic wastewater, manure and E.Coli colonies to distilled water. The prepared samples were introduced to continuous electrochemical reactor. The removal efficiency of electrolysis process was investigated in different conditions which include electrode material (copper and graphite compressed), reaction time (40, 50, 60 and 70 minutes), voltage 48V, distance of electrode 5 cm and the initial pH 7.
Results
The results indicate that removal efficiency depends on source of pollutant, reaction time, and type of electrode. Also the optimal efficiency for E.Coli colonies achieved in electrolysis instrument was as follows: electrode material = copper electrode, distance of electrode=5cm, applied voltage= 48V and reaction time=70 minute. Under these conditions removal efficiency was obtained 99%. No significant changes in pH, TDS and EC in different times and coliform bacteria were not created by changing the source.
Conclusions
According to the results of this study, using the electrolysis process with continuous flow, as a convenient method with high performance and environmentally, suggest for the disin fecting the water contaminated with fecal Coliform.
