Globally, aquatic ecosystems have been subjected to a wide variety of degradation forms. Sewage is considered one of the main sources of water bodies' pollution, contributing significantly to organic matter and nutrients loadings, as well as pharmaceuticals and pathogenic microorganisms. In terms of sanitation, black water corresponds to the effluent collected from toilets, basically containing faeces, urine and toilet paper, which represents about 57% of organic matter, 90% of nitrogen and 77% of phosphorus from the household wastewater. Considering that conventional wastewater treatment systems are mainly designed for the removal of organic matter and that those systems do not satisfactorily remove nutrients from sewage, it is necessary and urgent to investigate alternative treatments capable to achieve higher nitrogen and phosphorus removal as a way to supplement the usual employed systems. In this context, the main objective of this research project is to identify the key variables involved in nutrient removal by Chlorella sorokiniana in a tubular photobioreactor fed with UASB effluent treating simulated black water. The expectation is that the algal biomass rich in nitrogen and phosphorus removed from the effluent may be used as fertilizer, contributing doubly to the solution of environmental problems: treating an undesirable residue and generating a high valuable byproduct.
