Abstract
기술구성으로는 (a)수산화알루미늄(Al(OH)3)과 염산(HCl)을 투입하여 120~170℃의 온도로 5~10시간 동안 반응시켜 화학식(1)로 표현되는 Al2O3 함량이 15~18%로 조절된 폴리염화알루미늄(PAC)인 1차 반응물을 생성하는 단계와, (b)1차 반응물과 염기도 조절제로 염산(HCl)을 반응시키는 단계로 이루어진 화학식(2)로 표현되는 저염기도 폴리염화알루미늄(PACB)을 제조하는 것을 특징으로 한다.
발명의 제조방법에 따라 제조된 염기도가 10~20%이고, Al2O3 함량이 8~15%로 조절된 화학식(2)로 표현되는 저염기도 폴리염화알루미늄(PACB)은 우수한 응집성능이 유지되며, 장기간의 저장 기간 동안 고체상의 침전물이 석출되지 않는 등의 우수한 안정성을 나타낸다.
또한 음용수 및 하ㆍ폐수처리 과정에서 발생되는 슬러지의 부피를 감소시키고, 잔류알루미늄의 감소와 착색현상을 방지하며, 고탁도시에도 원활한 응집능력을 발휘하며, 조류 제거에도 효과를 나타낸다. 특히, 유기물 및 인의 제거효과가 우수하여 녹조현상등의 부영양화를 방지하는데 우수한 응집제의 특성을 갖는다.
