This proposal concerns the development and evaluation of a novel electrolytic coagulation/flotation system for water treatment. A limited amount of prior work has shown that the proposed technology may be significantly more effective, simpler and cheaper than equivalent existing methods. The system constists of an electrolytic reactor with reversible polarity aluminium electrodes, in which the bulk water to be treated passes through the reactor. During its passsage through the reactor the water is treated by coagulation/flocculation, arising from the anodic release of aluminium ions, and flotation separation of the floc precipitates due to the flow of hydrogen gas bubbles from the cathode plates.The aims of the project are primarily to develop an efficient electrolytic coagulation/flotation system for water treatment and to demonstrate its performance at pilot-scale under field test conditions. Laboratory-scale, fundamental work will investigate the influence of the design variables of the reactor and water quality, and identify the optimal operating conditions that minimise the specific electrical energy consumption and reactor dimensions, whilst maintaining efficient gas bubble formation. The pilot-scale evaluation, in collaboration with Thames Water Utilities, will consider the long term performance of the unit in direct comparison with an equivalent pilot-scale dissolved-air flotation process.
