Abstract

Treatment of municipal wastewater has become a global concern, and is expected to increase as water scarcity continues to increase. The efficient and effective treatment of wastewater is increasingly a subject of debate and contention. The present research statistically compares algal, aerobic, and anaerobic treatment methods, as based on data from prior research, to determine which are more efficient in removing certain nutrients from municipal wastewater. Chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) removal data was acquired from various contemporary studies and analyzed using ANOVA tests and T-Tests to determine if there was a statistically significant difference in the removal of those nutrients between the 3 treatment categories. While some tests proved inconclusive, it was found that the aerobic treatment method generally removed COD more quickly and effectively than the other methods, while the algal treatment method generally removed TN and TP more quickly and effectively than the other treatment methods.
