摘要：

Pilot studies showed that with water temperatures less than 37 degree F (3 degree C) and raw water turbidities less than 2 ntu, ferric chloride removed turbidity more efficiently than did aluminum sulfate but that aluminum sulfate caused slower head loss development. The total clogging head loss at the onset of turbidity breakthrough, however, was approximately the same for both coagulants. Equivalent head loss development and turbidity removal were demonstrated at a molar iron-to-aluminum dosage ratio of 3:5. 6.
