HIGH TURBIDITY AND COD REMOVAL IN RIVER WATER USING LOW DOSAGE PLANT-BASED TACCA LEONTOPETALOIDES FLOCCULANT (TBPF) FOLLOWED BY ACTIVATED CARBON TREATMENT

Pollution in river water affects human, plant and animal health activities, its removal using chemical coagulants is a huge concern. This study aims to reduce turbidity COD pollutants through coagulation-adsorption process by Tacca leontopetaloides biopolymer flocculant (TBPF) powder activated carbon (PAC). In coagulation experiment, TBPF dosages were varied evaluate the effect on Bioblock flocculator followed adsorption adding PAC. The results found that at 200 mg/L of dosage with 2000 PAC, maximum obtained 49% 81%, respectively. final loads 4.2 NTU 9.3 mg/L, respectively, which below standard limit set for CLASS IIB provided National Water Quality Standards Malaysia (NWQSM). High low environmental friendly plant-based TBPF-PAC this has great potential treatment, particularly domestic area.
