there is an increased awareness that biological ammonia conversion to nitrogen gas is not sustainable, due to N2O emissions and the energy requirement for aeration [11]. Nitrous oxide emissions vary greatly, but as much as 5% of the nitrogen load of a treatment plant can be emitted, depending...
Realising the need for a new water treatment solution to address these challenges, Baker Hughes, a GE company (BHGE), developed the Spectraclear treatment technology. A group of cationically charged organic polymers, these products can function as a coagulant, emulsion breaker or flocculant to tr...
Sewage and wastewater treatment plant performance: Challenges and the environmental impact 来自 钛学术 喜欢 0 阅读量: 24 作者: F Orata 摘要: The trend in sewage and wastewater treatment has been to direct sewage influent from sources such as domestic, municipal, agricultural, industrial and ...
8. Current status, challenges and future directions for wastewater management Wastewater treatment relies mainly on removing heavy metals and pollutants from pesticides, oils and dyes that are best treated by bioelectrochemical systems or MFCs. Though the conjugation of NPs with carbon electrodes increased...
this review studied and analyzed the main challenges affecting 20 municipal WWTPs. Moreover, we outlined the currently employed strategies and research issues pertaining to low temperature conditions. Low temperatures have been found to reduce the metabolism of microbes by 58% or more, thereby leading...
s PVB polymer manufacturing plant on site, till 2004. Since then, he has been working at the environmental department of the company, with particular responsibilities in improving the wastewater treatment plant and the combined sludge centrifuge-dryer installation. Being a Master Black Belt he is ...
Bacterial communities in wastewater treatment plants (WWTPs) affect plant functionality through their role in the removal of pollutants from wastewater. Bacterial communities vary extensively based on plant operating conditions and influent characteristics. The capacity of WWTPs can also affect the bacterial...
wastewater treatment processes are quite well established and most of the challenges arise as a result of increased load due to increased population, unexpected malfunctions that lead to off-spec water that needs to be re-treated or very heavy storms with rainfalls that overload the sewage plant...
The role of wastewater treatment plants in spreading microplastics to the environment poses additional threats that need to be treated. Thus, the key challenges remain in understanding the fate and occurrence of microplastics in the wastewater treatment plant and the ability to detect them at each ...
To identify possible hosts carrying the functional selected resistance genes, we assembled contigs from the deeply sequenced metagenome (AAW.5.2010). The relative low coverage of the functionally selected resistance genes challenges their assembly. In addition, the complexity of the WWTP community also ...
