Data were analyzed using a paired t-test to see the effect on the controlgroup and treatment group (p value <0.05). The research results showed that there was an effect of theindependent variable towards the dependent variable. The most influential treatment was a chlorine dose of 2gr/l and aeration for 4 hours with a percentage reduction in the total number of coliforms and TSS levels of82.71% and 85.16% respectively.
