Various techniques have been developed to treat the water before discharging into environment. One of such techniques is coagulation. In the current research a coagulant aid (Eucalyptus bark) has been identified as an effective addition which results in 11-15% decrease in overall consumption of primary coagulant (Aluminum sulfate). The objective of study is to reduce total suspended solids (TSS) and turbidity from the sewage water using a primary coagulant along with a natural coagulant aid. Maximum total suspended solids (TSS) removal is achieved using  aluminum sulfate and eucalyptus bark as natural coagulant aid at particle size of 60 mesh, pH of 8 at 1.0 g/L feed rate and temperature of 30 °C
