Requirement of seawed as raw materials in many industries which progressively mount have grown industries which process seawed rapidly grow. One of negative effect is contamination environment / pollution with their waste . Therefore the way of treatment in order not to contamination environment and can be exploited again is needed. This research reports waste water treaatment by chemical – physics using process of coagulation – floculation. Selected coagulan and used liquid waste ripening of bleaching earth.. Intention of the research is to degrade rate of COD , BOD and TSS . The results are rate COD 789,62 mg/L, rate BOD 386,12 mg/L, TSS 18,25 mg/L and pH 4 at volume coagulan 50 ml, 40 minute for time of strirrer.
