"The tofu industry is a small industry (home industry) that produces\r\nwastewater between 100-200 times the allowable limit and is usually\r\ndischarged directly into water bodies, thus polluting the environment. This\r\nstudy aims to combine the coagulation method (stage 1) using\r\nPolyalumunium Chloride (PAC) with filtration (stage 2) on several\r\nvariations of materials (quartz, activated carbon, and zeolite). The study\r\nwas conducted with six replications. The comparison of waste quality (BOD,\r\nCOD) was observed at each stage of the study. The SAS 9.4 was used for data\r\nanalysis, including the application of the T-test and ANOVA. The study\r\nfound that coagulation with PAC 690 mg/L reduced BOD by 51.7% and a\r\ndose of 765 mg/L by 61.1%. In the COD parameter, the reductions were\r\n65.84% and 67.55%. In the second stage (filtration), the reduction in BOD\r\nwas higher in activated carbon (79.33%) compared to zeolite (78.67%) and\r\nquartz (75.46%). Activated carbon also had the most COD reduction effect\r\n(73.22%). Although the statistical results showed significant differences in\r\nall doses and media, the use of 765 mg / L PAC and activated carbon\r\nfiltration had the most effect on reducing BOD and COD of tofu industrial\r\nwastewater. This research can be used as an alternative in the physical\r\nprocessing of tofu industrial wastewater."^^ . "2021-06-07" . . . "Poltekkes Tanjungkarang"^^ . . .
