초록

In results of accomplishing fundamental study to improve the flocculant-mixing of the Flash-Mixer in Onsan Water-Treatment Plant at the small cost, We obtained 8.9% of mixing-efficiency from the field data and 3.2% of the characteristic flow-ratio as the available maximum volume-ratio in this Water-Treatment Plant. The optimum elements with the deflector diameter of 400 mm and deflector angle of $145^{\circ}$ at the flow ratio of 3.2% could be obtained from the expanded study on the ground of the fundamental study. Finally, the efficiency could be improved about 510% from 8.9% to 45.4% and the average turbidity could be improved about 14%.
