“…The analysis of the resulting flocs does show that E. coli are effectively killed. Similar results were obtained by Ghernaout et al (2008) when they applied electrocoagulation in the E. coli culture and the two surface waters. In fact, they noted that, some either the initial pH and with ordinary iron electrodes, a wastewater retention time of at least 30 min is required to have transparent solution, which corresponds according to the method used to efficiency around 100 %.…”

“…In the case of log (UFC/100 mL), a 1.15, 1.92 and 3.3 log units reduction in E. coli are observed for carbon graphite, aluminum and ordinary steel, respectively. These results do not match those got by Ghernaout et al in 2008 during the application of electrocoagulation in the E. coli culture in two surface waters. In fact, these authors concluded that aluminum is more efficient than ordinary steel.…”

“…Indeed, some studies have already been devoted to this subject, but many aspects of the process remain unknown such as the influence of the key parameters of electrocoagulation (Ghernaout et al 2008;Zhu et al 2005). In order to elucidate the role of the flocs formed during electrocoagulation on the inactivation of E. coli, the work will focused on the effect of electrode material and supporting electrolyte.…”

Laboratory experiments were carried out to investigate the mechanisms of electrochemical disinfection of artificial wastewater contaminated by Escherichia coli culture (5 9 10 5 UFC/100 mL) using electrocoagulation. In order to go deeply into the mechanism of the process, the behaviors of two dissolved-type electrodes (ordinary steel and aluminum) and a non-dissolved-type (carbon graphite) electrode were compared. The ordinary steel electrode was found more efficient for E. coli cells destruction compared to aluminum and carbon graphite electrodes. In order to determine the most favorable condition for the treatment, the effect of various supporting electrolytes including, sodium chloride, sodium sulfate and sodium nitrate, was scrutinized. E. coli is inactivated by 5 log units for a charge loading of 37.30 F/m 3 for sodium sulfate, 24.87 F/m 3 for sodium nitrate and 12.43 F/m 3 for sodium chloride. It thus appears that the most favorable supporting electrolyte type for this method of disinfection is sodium chloride, a fact which can be explained by the formation of disinfectant byproducts such as chlorine dioxide, hypochlorite ions and perchlorate ions. From the results obtained, electrocoagulation applied to the elimination of E. coli proceeds through three combined effects: the electric field, the actions of oxidants electrogenerated during the process and the adsorption by the metallic hydroxides formed in solution.

The effect of aluminium cookware on inactivation of Escherichia coli in milk was studied. Samples in aluminium and stainless-steel cups were heated at 60, 63, 65 and 67℃ and held at those temperatures for 25, 5, 3 and 2 min, respectively. Results obtained under the temperature of 65 and 67℃ clearly showed that cells of E. coli were killed more rapidly in aluminium cups than in stainless-steel cups. D-values in the aluminium cups were significantly shorter than those in stainless-steel cups, especially at higher temperatures. Samples in aluminium cups revealed a better trend inactivation effect than in stainless-steel cups at 60 and 63℃, however, there were no significant difference. Considering on z-values, results which obtained by aluminium cups were slightly lower than that obtained by stainless-steel cups. These results indicate that an aluminium utensil has an inactivating effect on E. coli and that rate of inactivation increases as temperature increases.

“…The maturation of municipal water purification in the last decades has authorized cities in the developed countries to be mostly without of waterborne diseases. Since the application of filtration and disinfection of potable water in the United States, waterborne diseases like cholera and typhoid have been almost removed (Bond et al, 2012;Weiner, 2012;Gopal et al, 2007;Liviac et al, 2011;Ghernaout et al, 2008;.…”

The generation, monitoring, and health impacts of disinfection by-products (DBPs) in potable water are problems of worldwide worry. Several nations, besides the World Health Organization, possess regulations and/or guidelines on bearable levels of DBPs in water. Since drinking water is frequently remediated using a chemical killing agent, DBPs are pollutants to which several humans are unprotected. On account of the health impacts linked to subjection to chlorinated water and/or some DBPs, the water manufacturing has performed great endeavors to equilibrate killing pathogens and DBP monitoring. Large survey has been realized on rising DBPs of health and regulatory worry. In spite of the fact that the attention on DBPs was previously on chlorine-and bromine-containing carbonaceous DBPs, appearing DBPs comprise iodine-containing species, also halogenated and non-halogenated nitrogenous DBPs. In addition, latest toxicity experimentation has proposed that certain of the more recent PBPs are of more elevated toxicity than some of the regulated chemical products. Therefore, survey has been realized to better comprehend how to costeffectively monitor a large interval of regulated and appearing DBPs. This comprises the usage of advanced remediation and killing pathogens methodologies. This paper shows certain of the newest research works at comprehending these significant DBP-related problems. Disinfection is killing microorganisms present in water; but, it is as well killing human beings drinking water by poisonous DBPs. Using chemicals for water treatment is finally a lost cause.
