This research was conducted to investigate the coagulant dispersion distribution in the selected full-scale pump diffusion mixers(PDM), and to evaluate their performance through wet test experimentally. The wet tests was to measure the factual zeta-potential all over the cross section at a distance of 4.5D(D=1,200mm) from deflector in the selected PDMs on various conditions of the pressurized/the main water inlet flow-rate ratios. From the wet tests, in the case that the pressurized / the main water inlet flow rate ratio was less than 2%, the injected coagulant was distributed unevenly and dispersed locally. On the other hand, in the case of 4% the coagulant dispersion distribution was relatively even. Also, in the case of over 8%, comparing with any other condition, the injected coagulant was dispersed most equitably all over cross section. |
