Abstract

Our current research includes treating the toxicity of wastewater using green algae, and this is done through a set of steps that involve withdrawing nitrogen and phosphorus from wastewater for algae to benefit from them in their growth, leading to a clear reduction in their concentrations. Since the algae depend on self-feeding for their living so that they carry out the process of photosynthesis, they thus consume carbon dioxide that is produced from the process of decomposing organic carbon in wastewater by the action of bacteria that work on consuming the oxygen liberated from the algae during the process of photosynthesis, and this leads to reducing carbon dioxide emissions on the one hand and reduces the requirements for ventilation necessary for the work of bacteria on the other hand. Quantitative analysis illustrates that 1.83 grams of carbon dioxide are consumed for every gram of algal biomass. This study highlights the effectiveness of algae as a sustainable and green method for treating wastewater.
