Abstract

Microalgae based biological treatment aiding in nutrient reduction in wastewater has attained growing interest in the wastewater remediation industry.  This study focuses on the degradation of phenol and p-chlorophenol by microalgae, NH4+-N reduction, biomass residue, and flocculation efficiency of the microalgae. The microalgae culture was utilized for testing with a phenol compound with several concentrations, i.e., 10, 30, 50, 75, and 100 mg/L. To measure the degradation of concentration of the phenolic compound concentration in each bioreactor, the UV-VIS spectrometer is used. Consequently, NH4+-N, biomass residue, and flocculation efficiency were measured by means of titrimetric method and UV-VIS spectroscopy. These testing was conducted within 0 hour to 192 hours corresponding to eight days.
