Electrochemical disinfection, an environmentally acceptable method of drinking water disinfection?

Effect of electrode material and supporting electrolyte on the treatment of water containing Escherichia coli by electrocoagulation

“…Similar results were obtained by Kerwick et al (2005), who found the electrochemical disinfection most effective in water containing chloride in comparison with water containing phosphate and sulfate.…”

“…As a result of those disadvantages, a number of alternatives to chlorine for drinking water disinfection have been suggested. They can be of: (1) chemical nature such as ozonation; (2) physicochemical nature such as titanium photocatalysis, photodynamic disinfection and electrochemical disinfection; (3) and physical such as ultraviolet irradiation, pulsed electric fields and irradiation magnetic enhanced disinfection (Kerwick et al 2005). Apart from electrochemical disinfection, most of these systems are quite expensive and thus less convenient.…”

Conductive diamond electrodes for water purification

“…Despite the effectiveness of chlorine as a method of water disinfection, disadvantages like unfavorable taste and odor, its ineffectiveness when used alone against some resistant microorganisms, and the generation of products potentially toxic such as chloroform (the most common chemical by-product of water disinfection, considered harmful for its cancer risks) 40 , were the main reasons for searching alternative disinfection methods. Therefore, new electrochemical .00 nm 500.00 nm methods are developed to establish chlorine-free systems, oxygenbased disinfection, avoiding the drawbacks of chlorine and the generation of harmful by-products.…”

“…Based on the literature, several groups have reported different experimental results using diamond electrode for purification/disinfection water, under different conditions [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] . However, the most relevant publications were taken into consideration here for illustrating the advances of this kind of electrochemical application.…”

Conventional and Alternative Disinfection Methods of Legionella in Water Distribution Systems – Review

“…Since each conventional disinfection method has advantages and disadvantages, the optimum method has not been identified. Insufficient disinfection efficacy followed by occasional outbreaks of Legionella caused diseases and identification of chlorine as a source of potentially harmful disinfection byproducts [8], [17], [18], [19] have led to intensive research to develop alternative disinfection techniques [2], [3], [16]- [18], [20]. Objectives of this paper are to provide an overview of conventional disinfection methods, to assess their advantages and drawbacks, and to provide an insight into research on alternative disinfection approaches.…”
