수용액내에 부유하고 있는 화이트카본 미립자의 효율적인 제거를 위한 방법으로 내부원통이 회전하는 수평 쿠엣트 응집기를 사용하여 고분자응집제의 첨가하에서 연속계의 응집현상을 관찰하였다. Taylor수, 평균속도구배와 교반시간이 응집에 미치는 영향을 실험으로 살펴보았으며 응집정도는 평균침강속도, 투과도 및 침전물의 체적 등으로 측정되었다. 이로부터 응집은 교반시간 초기에 급격히 일어나고, 1000<Ta<2500 영역에서는 약 100초의 최적교반시간이 존재하였으며 Ta

The continuous flocculation to remove fine particles of White Carbon suspended in the water was investigated experimentally by using the horizontal Couette flocculator of which the inner cylinder is rotating. The effects of the Taylor number, the mean velocity gradient and the relention time on flocculation caused by a polymer flocculant were examined systematically. The extent of flocculation was decided by measuring the average settling rate, the light transmittance and the volume of sediment. It was found that particles were flocculated very easily at a very short retention time. The optimum retention time was about 100 seconds in the region of 1000<Ta<2500 and the best flocculation was produced at Ta
