Alum Dose In Water Treatment

Alum Dose In Water Treatment. Survey, the average aluminum concentration in treated water at facilities using aluminum sulfate coagulation ranged from 0.01 to 1.3 mg/litre, with an overall average of 0.16 mg/litre. I am wondering what formula would i use to calculate dosage mg/l.

When added to water, al ions hydrolyze rapidly and form a range of metal hydrolysis species (jiang 2015). The needed dose varies with the ph of the water and the size of the particles. Determine the gallons per day setting for the alum solution feeder if the liquid alum contains 5.36 lb of alum per gallon of solution.

For example, liquid alum at 7.5% w/w al2o3 has 7.5 kg of al2o3 in solution for every 100 kg of liquid chemical delivered. The treatment process uses iron alum for coagulation and flocculation.

For example, a dose of 12 mg/l pacl (as 100%) was required for treatment of a coloured, low turbidity water (otway region, victoria) compared to similar performance obtained when using an alum dose of 55 mg/l, and Water can be reduced by utilising the conventional water treatment practices of flocculation and filtration.
