Aluminium Sulphate Jar Test

Jar test for determining "Coagulant" dosage in Water

03.01.2013ยท 1. Take 1000 ml of given sample in 6 beakers. 2. Find the pH of the sample and adjust it to 6 to 8.5. 3. Now add 1 ml, 2 ml, 4 ml, 8 ml, 10 ml, 12 ml of alum respectively in each one of the beakers. 4. Now insert the paddle of the jar testing apparatus inside the beakers and start it. 5.

Comparative Assessment of Performance of Aluminium

aluminium sulphate, ferric chloride and ferrous sulphate for water treatment7. Determining the optimum coagulant dosage for a given raw water is a major problem. Jar test procedure with a six-unit multiple stirrer system has been commonly used to determine the required concentration of coagulant dosage [7-11]. This is generally

narrow, ranging from about 6.5-7.5. The comparable range for ferric sulphate is considerably broader, a pH range of about 5.5-9.0 (Fig. 14.1). When the results of a jar test are plotted, this type of curve is typical. The most common method of dosing the alum or ferric sulphate is in the form of a solution.
