Pilot studies showed that with water temperatures < 27 degrees F (3 degrees C) and raw water turbidities < 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-toaluminum dosage ratio of 3:5.6. Includes 9 references, tables, figures.
