An apparatus to disinfect water comprises a reverse electrodialysis (RED) cell 1 to generate electric power and an electrolysis cell 6 electrically powered by the RED cell to generate chlorine or hypochlorite disinfectant from brine discharged to the electrolysis cell 1 from the reverse electrodialysis cell. The concentrated brine solution is preferably made up to 250 g/l of sodium chloride, and the flow rate of the input is set to produce a dilute stream output having a concentration of 25 g/l of sodium chloride for passage to the electrolysis cell. The apparatus is self-contained and may be used to disinfect water at remote sites, the only inputs needed being salt and water. <IMAGE> |
