Abstract

The excess content of nutrients in the water can cause eutrophication which has an impact on increasing turbidity and causing anoxic conditions in a waters. High Rate Algae Reactor (HRAR) is wastewater treatment and nutrient recycling based on symbiotic interactions between heterotropic bacteria and algae cells that live in waters. The aim of this research was to determine the efficiency of nutrient removal and the effect of aeration with the correlation of additional parameters. This research was implemented in a batches for 9 days with variations of aeration. Parameters analyzed were Chlorophyll-a, COD, Nitrate (NO3) and Phosphate (PO4) as the main parameter whose analysis is conducted every 3 days and for additional parameters such as DO, pH, light also emperature are carried out every day. The results of the study show HRAR's ability to reduce nitrate (NO3) and phosphate (PO4), the best removal results on 24-hour aeration are 43% and 38% with initial concentrations of 56.55 mg/L and 5.61 mg/L. The greater the chlorophyll-a concentration (algae) in the reactor, the greater the level of removal efficiency in nutrients.
