“…Zhang et al [26], indicated a 98.6% BOD removal using MFC while Marassi et al [27] reported a 96-97% efficiency using a tubular MFC. The use of microalgae has also been reported to have effectively reduce the BOD content of wastewater by generation of O 2 during photosynthesis [28] and 87% removal efficiency [29].…”

The quality of freshwater and its supply, particularly for domestic and industrial purposes are waning due to urbanization and inefficient conventional wastewater treatment (WWT) processes. For decades, conventional WWT processes have succeeded to some extent in treating effluents to meet standard discharge requirements. However, improvements in WWT are necessary to render treated wastewater for re-use in the industrial, agricultural, and domestic sectors. Three emerging technologies including membrane technology, microbial fuel cells and microalgae, as well as WWT strategies are discussed in this chapter. These applications are a promising alternative for manifold WWT processes and distribution systems in mitigating contaminants to meet acceptable limitations. The basic principles, types and applications, merits, and demerits of the aforementioned technologies are addressed in relation to their current limitations and future research needs. The development in WWT blueprints will augment the application of these emerging technologies for sustainable management and water conservation, with re-use strategies.

The aim of this study is to determine the bacterial compositions during the bio-drying process of sewage sludge. Bio-dried products and sewage sludge were randomly collected from the Wupa wastewater/sludge treatment plant in Idu Industrial area Abuja, Federal Capital Territory, Nigeria. A mixture of sewage sludge and sawdust that were bio–dried and cured before this experiment were composition of the bio–dried product. The bacterial communities were analyzed in the laboratory using Pour Plate Technique to examine the total bacterial present in the sewage sludge bio-drying material (SSBM) and the bacterial were later isolated using other techniques like Oxidase test, Catalase test, Grams Staining technique and Spread Plate Technique. Evaporation of free water and water formation was determined by humidity gauge and moisture-oven drying method. From the results obtained, Acinetobacter was the most abundant bacterial during the initial and final thermophilic phases (43% and 37%) respectively. Bacillus was the most abundant amid the cooling stage (53%). The water evaporation and water generation rate were credited to the degradation of organic content of the SSBM and heat produced by bacterial activities. From this study, there is a clear indication that the bacterial density grades that increase the temperature of the SSBM during the bio–drying process reshaped the bacterial communities.
