Based on this study, it was revealed that the combination of alum, peat, and lime could neutralise pH and remove color, turbidity, and organic content. Optimum removal was achieved with alum, peat soil, and lime content of 40 gr/l; 40 gr/l, and 20 gr/l, consecutively. The pH changed from 7,06 to 7,86 , while the removal of color, turbidity, and organic content was 97,5 % (from 500 TCU to 12,5 TCU), 98,5 % (from 119,66 TCU to 1,8 TCU), and 90 % (from 476,55 TCU to 47,48 TCU).
