With the concerns of global climate change, the significant changes in rainfall patterns have aggravated the occurrence of pollutants from agricultural uplands. Heavy and intensive rainfalls have rinsed a variety of pollutants off the land, sending them into the neighboring water environments which further causes water pollution problems. Recently, the application of PAM(Polyacrylamide) in agricultural lands has gotten much attention for soil conditioning. Therefore, this study aimed to develop the automatic control system applying the chemical flocculant, liquid PAM in order to flocculate the suspended solids and deposit at the bottom of farmland water channel, so eventually minimize the amount of non-point pollutants discharged into receiving water. The optimum feed rate for liquid PAM was calculated through the experiment in artificial water channel and applied to the control system. As the results of the performance test of the automatic turbid water control system installed in the sloped field, the range of turbidity reduction rate was 25 to 33% with the average turbidity of 292 to 498 NTU in water channel.
