| Abstract |
| The aim of this study was to investigate the nutrient removal and biomass productivity in the Kimchi wastewater using microalgae. The experiment operated for 6 days in the OPPBR (Optical Panel Photobioreactor), and using marin microalgae as Nannochloris sp. The obtained result indicated that the biomass productivity of 1.207 g/L from 0.367 g/L initial concentration in 6 days was reached with light transmittance of 92% at a 305 mm depth in the OPPBR. The total consumption rates of BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) in the OPPBR were found to be 98.06% and 87.34%, respectively. Additionally, the removal rates of TN, NO3-N, TP and PO4-P were 86.21%, 77.81%, 94.87% and 93.00% in Kimchi wastewater using Nannochloris sp., respectively. These results indicated that the OPPBR process with Nannochloris sp. was highly effective for COD, BOD and nutrient removal compared to the conventional biological process in the kimchi wastewater. Therefore, the OPPBR process with Nannochloris sp. was effective for nutrient removal and biomass productivity and can be applied to treat kimchi wastewater in treatment plant. |
