摘要: The methods of separation microalgae has a significant impact in the economic aspects their cultivation. In this study, pine bark was used as substrate for immobilization microalgal biomass cultivated raw municipal sewage. experiment conducted cylindrical photobioreactors (PBRs) with circulation wastewater. Biomass 42 days. After that time, abundant growth biofilm on surface well improvement quality treated sewage were observed. efficiency removal nutrients from wastewater 64–81% total nitrogen and 97–99% phosphorus. Moreover, concentration suspended solids reduced, which resulted decrease turbidity by more than 90%. Colorimetric analysis Volatile Matter (VM) content showed Higher Heating Value (HHV) VM due to proliferation biofilm.
