It is also importantto reduce the amount of organic compounds in the wastewaterdischarged from sewage treatment plants into rivers. If this doesnot happen, naturally occurring microorganisms in rivers willuse organic compounds as an energy source and grow in largenumbers. Because they breathe ...
In this study, activated sludges from two laboratory units and twelve sewage treatment plants were examined to develop a relationship between the quantity of filamentous microorganisms and settling characteristics. Using 14-cm diameter, 69-cm liquid depth settling columns, activated sludge characteristics,...
As a result, except for a small amount of PPCPs that are released into the atmosphere by escape, some portion of PPCPs remains in the effluent of the wastewater treatment plant, with the remainder present in excess sludge due to adsorption or dissolution [12]. The Water Pollution Prevention...
those of RC were not significant (P > 0.05). The RC affected microorganisms through altering NP toxicity, microbial quantity and activity, but not microbial community structures. This study indicated that there could be an optimal biochar percentage in biochar-sediment systems at different HOC ...
Meanwhile, the microorganism carries negative charges; this induces electromagnetic attraction between the metal oxides and the microorganisms, causing oxidization and death of microorganisms [46]. Therefore, the current perspective is based primarily on assessing the efficacy of aqueous exposure of TDNG...
The phylum Chloroflexi is highly abundant in a wide variety of wastewater treatment bioreactors. It has been suggested that they play relevant roles in these ecosystems, particularly in degrading carbon compounds and on structuring flocs or granules. Nev
The first food waste anaerobic digestion plant in Britain to be built at a sewage treatment plant is the city of Bristol. The plant, located at a Wessex Water sewage works in Avonmouth, process 40,000 tonnes of food waste a year from homes, supermarkets and business across the southwest and...
microorganisms. The most generous approach is methanogenesis, in which metabolically active methanogens assist CO2in producing CH4via metallic NPs.Geobacterspecies use their methanol metabolism genes in bacterial aggregates, and metallic NPs (Fe, Ni, Cu, Co, and their complexes, such as Au-SH-SiO2...
NSG and PCR based surveys provide crucial information about abundances and diversity of the key bacterial groups, but do not cover functionality aspects of the complex microbial communities. Therefore, the additional metatranscriptome i.e. profile of the overall gene expression of microorganisms in parti...
1.2. Microbial degradation of organic micropollutants in wastewater treatment plants In addition to the physical and chemical techniques currently used in WWTPs to remove solids and pollutants, microorganisms continue to have a central role in wastewater treatment (Carey and Migliaccio, 2009). Microorgani...
