Impact of Various Concentration of Phenol and p-Chlorophenol to the Microalgal Population in Wastewater

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,biomassresidue, and flocculation efficiency were measured by means of titrimetric method and UV-VIS spectroscopy. These testing were conducted within 0 hour to192 hours corresponding to eight days.
