Abstract

In the current study, laboratory experiments were conducted using a moving bed bioreactor carrier (MBBRC) to investigate the ability of two blue-green algae genera (Anabaena sp. and Scenedesmus sp.) and two bacteria genera (Lactobacillus sp. and Azotobacter sp.) and remove ammonia from contaminated water. The results of this study revealed that using single algal species achieved a maximum removal percentage of 30% for ammonia concentrations ranging from 5 to 7.5mg/ l, while the utilization of two mixed algal species resulted in ammonia removal percentages ranging from 6% to 12% at retention times from 15 to 60 minutes. On the other hand, using each of the two algal species separately at retention times of 2 and 5 hours resulted in removal percentages ranging from 85% to 100%. Additionally, the study found that the application of bacterial genera (Lactobacillus sp. and Azotobacter sp.) on raw water samples with an average ammonia concentration of 7.8 mg/l, and the utilization of bacterial content within the range of 100-200 ml per 1-liter volume of raw water samples demonstrated a remarkable maximum removal efficiency of 100%, with varied retention times up to 2 hours.
