Abstract

Due to its gelling abilities, calcium alginate has been investigated in this work as a possible coagulant to be used in turbid water treatment. Sodium salts of commercially available alginic acid with low and high viscosities were used in the study. A standard jar test was conducted in 500 mL of synthetic turbid water samples with different initial turbidities of 150, 80 and 10 NTU. These samples were treated using different doses of calcium (varying between 30 and 200 mg/L) and alginate (varying between 0.001 and 10 mg/L).
