| Summary: | In this study, artificial support material was tested to determine the removal capacity of organic pollutants and nutrients on a laboratory scale using the PFR system. The test is carried out using water with the addition of chemicals so that it has characteristics similar to Cikapayang River water in 2018, where the simulated water conditions are rainwater which is potentially polluted by wastewater. This study uses three variations of C: N: P which are (30 mg/l, 75 mg/l, 180 mg/l): (15 mg/l, 25 mg/l, 35 mg/l): (1 mg/l , 2 mg/l, 3 mg/l) with carbon sources derived from glucose, nitrogen sources from sodium chloride, phosphate sources from potassium dihydrogen phosphate, and the addition of TSS substance without variations originating from clay. The experiment was carried out with three of 10.78 L PFR, made of PVC pipes filled with an inert chemical substrate called rockwool as an artificial support material. The process of removing pollutants in the PFR relies on a biological layer that is grown on the surface of the material support through biomass seeding from domestic aeration tanks. The laboratory analysis includes water absorption capacity, SEM test and wastewater parameter test. Organic substrate removal rate compared with prediction of 1st order and Strover-Kincannon substrate removal model. The results showed that the maximum removal efficiency of TSS, TN, TP, and COD were 95%, 93%, 98%, and 96%, respectively. The maximum water absorption capacity is 30.8%. The Strover-Kincannon model and second order substrate removal were found to be the most appropriate model for this experiment with PFR, where this model provides a high correlation coefficient of 90%,and have kinetic parameters Umax 9.3196 gram COD l/day, KB 10.6906 g.l/day, k2 4.97/day, m 0.0272/day dan n 1.0848 so this model can be used to predict the behavior or design of PFR in this case.. |
