摘要： 본 발명은 산업 폐수를 증발 농축기를 사용하여 처리하는 경우에 있어서 야기되는 농축기 내의 스케일 부착 방지 방법에 관한 것이다. 본 발명의 방법은 증발 농축기에 유입될 폐수에 대해 pH를 2 내지 10 범위로 조절하여 상온 내지 50 ℃ 범위에서 염화바륨을 첨가하여 30 분 내지 2 시간 동안 교반시켜 폐수 중의 황산 이온을 침전 제거시키고, 이어서 계면 활성제를 폐수 기준으로 10 ppm 내지 0.1 중량% 첨가시켜 표면 장력을 35 dyne/cm 이하로 감소시키는 처리를 수행하는 것으로 이루어진다. 본 발명의 방법에 따르면, 스케일 제거를 위해 농축기의 가동을 중지시키는 일이 없이 장기간 처리 효율을 유지시킬 수 있으며, 처리 비용이 매우 저렴하고 장치 부식 문제를 전혀 야기시키지 않는다.
