Abstract
Lake water contaminated with domestic wastewater is a serious concern because it can pollute the surrounding environment, such as in Telaga Rambit, Gresik. Turbid water quality indicates pollution so that a treatment process is needed before use. This study aims to analyze the effect of activator type and flow rate on the filtration process using the slow sand filter (SSF) method, with a combination of coconut shell charcoal and rice husk charcoal media. The flow rate variations used were 0.1 m³/h and 0.3 m³/h, with hydrochloric acid (HCl) and phosphoric acid (H₃PO₄) activators. The results showed that Reactor B, which used H₃PO₄ with a flow rate of 0.1 m³/hour, was the most effective variation in reducing contaminant levels, namely BOD by 1.9 mg/L, COD by 6.26 mg/L, and TSS by 12 mg/l with the 25th sampling time. H₃PO₄ activator is proven to increase the adsorption ability of activated carbon media, especially in capturing suspended particles. The low flow rate also provided better stability during the filtration process, allowing for more effective particle retention. At 25 minutes, the filtration media had not reached saturation point, indicating that filtration could still improve with longer contact times. Keywords: Activator, Activated Carbon, Flow Rate, Slow Sand Filter
