Abstract

The Wastewater Treatment Plant (WWTP) at Politeknik STTT Bandung treats liquid waste using a coagulation-flocculation method with Poly Aluminium Chloride (PAC) and anionic flocculant; however, the optimum dosage of these chemicals has never been determined. This study aims to determine the optimum concentration of PAC and anionic flocculant and analyze the efficiency of pollutant removal and treatment costs. The jar test method was employed by varying the concentrations of PAC (100, 200, 300 mg/L) and anionic flocculant (0, 5, 10, 15 mg/L) on wastewater samples. The effectiveness of each treatment was analyzed based on the parameters of Total Solids (TS), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), color, and turbidity. The results showed that the optimum concentration was 200 mg/L of PAC and 5 mg/L of anionic flocculant. At this dosage, the removal efficiency achieved was very high for COD (95%), BOD (81%), TSS (81%), and turbidity (83%), and significant for TS (69%), and TDS (50%). The treatment cost required to achieve this efficiency is IDR 52,171 per cubic meter. It was concluded that the optimization of coagulant and flocculant dosages successfully and significantly improved liquid waste treatment performance at an efficient cost, thus it is recommended for application in the WWTP's operation.

Abstract

Reducing heavy metal concentrations in wastewater remains a major challenge in industrial waste treatment, including textile wastewater. One effective and economical method is filtration using porous adsorbent media. This study aimed to evaluate the effectiveness of filtration media based on palm oil mill fly ash and zeolite in reducing heavy metal concentrations in textile wastewater. The filtration process was carried out using a layered filter system with four different media arrangement models to adsorb pollutants from wastewater. The results showed that the filtration system significantly reduced heavy metal concentrations, with an average removal efficiency of 85%. The quality of wastewater after filtration using fly ash and zeolite media with pH of 7, TSS of 0.2 mg/L, and Cr concentration of 0.065 mg/L. The best filtration performance was achieved by Model A, with the media arrangement consisting of (1) coarse zeolite, (2) fine zeolite, (3) fly ash, and (4) cotton fiber. This media combination has strong potential as a simple, effective, and environmentally friendly technology for textile wastewater treatment.
