“…Filtration can be used in combination with the other disinfection technologies as they are very effective in removing the larger organisms. The chemical methods for disinfection includes, use of chlorination, electrochlorination, ozonation and hydrogen peroxide [5][6][7][8]. In chlorination, chlorine gas is dosed in water which destroy cell walls of the organisms which leads to their death.…”

The electrochemical treatment of brackish and seawaters with boron doped diamond anodes (BDD) can be particularly suitable for the removal of microorganisms, microalgae and pollutants: the high conductivity of these waters and the high content of chloride ions can be exploited in disinfection/oxidation processes mediated by active chlorine. A correct choice of operating conditions can limit the formation of such undesired by-products as bromate and chlorate ions. RESULTS: Galvanostatic electrolyses of synthetic waters containing chloride and/or bromide ions using BDD anode were carried out both in batch and continuous mode in an undivided cell. Bromide ions were oxidized to form bromate ions with high conversion rate, while chlorate ions were found as by-products of the oxidation of chloride ions together with active chlorine. When solutions containing Br- and Cl- were treated, the increase in the concentration of chloride up to that of seawater (20 g dm-3), hinders the formation of BrO3 - and ClO3 -. CONCLUSIONS: The electrochemical process with BDD anode could be applicable to the disinfection of high salinity waters: in synthetic solution simulating the composition of seawaters, high amounts of active chlorine are formed and the occurrence of bromates and chlorates is highly limited

“…It was shown that UV disinfection by itself or in combination with hydrogen peroxide can safely inactivate biological and chemical contaminants in water. Nanayakkara et al (2011) developed an electrochemical technology to treat ballast water. The ballast tank corrosion was not worsened due to the application of this technology.…”
