In operation water is pumped into the first chamber where it is treated with the first set of plates. It can then flow into a second chamber, with a barrier mechanism that limits the surface floe from flowing with it. This process can be repeated in other chambers until the water is adequately treated with different sets of plates. The water can then flow into additional chambers in which much of the residual floe and bubbles floats to the surface. Each chamber has a wall over which the floe can flow into a drain mechanism, and a mechanism for getting the floe to flow over the wall. In this manner these continuous flow electroflocculation water treatment systems operate like a membrane free filter or a chemical free dissolved air flotation system. | 10-23-2014 |
