This document reports on a jar test experiment to determine the optimum dosage of alum for water treatment. Various concentrations of alum between 0-45 ml were added to samples of 800 ml water in separate beakers. The treated water was tested for turbidity using a turbidimeter. The results showed that turbidity decreased with increasing alum concentration up to a minimum value, then increased again at higher concentrations. A graph of the data revealed that the optimum alum concentration was 80.7 mg/l, whic
