Abstract

This study aimed to determine the efficiency of media pollutant removal from municipal wastewater with high concentrations of ammonia and phosphorus in constructed wetlands  (CWs). The study utilized secondary data from previous studies that were published in credible sources. The removal efficiencies of the five media used in the constructed wetland, namely, peat-cattails, cattails, peat, Viteveria zizanioides, and Phragmite karka, were compared. The results showed that CWs with Viteveria zizaniode exhibited the best performance on average, removing 84% nitrogen and 86% phosphorus. Peat was also effective in attenuating pH. Humic and fulvic acids in peat moss can be released quickly in an aqueous environment under alkaline conditions, effectively lowering the pH value. The combination of Viteveria zizaniode and peat significantly improved pollutant removal efficiency in municipal wastewater with high concentrations of ammonia and phosphorus.

Abstract

Heavy metal (loids) in wastewater persists as a contagious and non-biodegradable environmental pollutant. With the ever rising of nanotechnologies in various field, there is a mass flux of heavy metal (loid)s being transmitted in many water sediments includes wastewater and rivers in which difficult to eliminate through conventional treatment processes. The introduction and development of nanomaterials have been increasingly utilized. Their high absorption capacity and unique properties in eliminating heavy metal pollutants and other nano pollutants have been extensively used in the remediation of inorganic pollutants. This review study illustrates the different types of nanomaterials that are utilized in various treatment process such as nano zero-valent iron (nZVI), carbon nanotubes and titanium dioxide nanoparticles (TiO2NPs). The mechanism of each nanomaterial and also its advantages and disadvantages are being portrayed. The identified factors affecting their efficiency in eliminating heavy metal and other inorganic pollutants are briefly described.
