【 摘 要 】

Algae technology is an alternative sustainable domestic wastewater treatment. This study analyse the effect of adding CO2 gas to algae reactor systems to reduce ammonia levels in wastewater. The addition of CO2 is expected to improve the performance of algae in photosynthesis thus accelerate the decreasing of ammonia concentration. This research uses algae reactor to treat domestic wastewater from Sewon Wastewater Management Installation Waste, Yogyakarta that conducted in laboratory scale with potential algae in facultative pond in Sewon WWTP. The CO2 supply in rate of 0.2 L / min and 0.5 L / min. Chlorophyll-a is analyzed to determine algae growth. The results show the high correlation between chlorophyll-a and ammonia removal, meanwhile algae reactor without CO2 is uncorrelated with ammonia removal.
