Due to the growing scarcity of water resources, wastewater reuse has become one most effective solutions for industrial consumption. However, various factors can detrimentally affect performance a treatment plant (WWTP), which is considered risk not fulfilling effluent requirements. Thus, ensure quality treated wastewater, it essential analyze system failure causes and their potential outcomes ...

A laboratory-scale membrane bioreactor (MBR) and nanofiltration (NF) hybrid system has been built to investigate effects of changes in characteristics of effluent organic matter by the MBR on fouling characteristics of the NF membranes. Large amounts of polysaccharide-like substances with small molecular weight and strong fluorescence intensity at the excitation wavelength of 230nm and the emis...

Surface coal mining in Appalachia has caused extensive replacement of forest with non-forested land cover, much of which is unmanaged and unproductive. Although forested ecosystems are valued by society for both marketable products and ecosystem services, forests have not been restored on most Appalachian mined lands because traditional reclamation practices, encouraged by regulatory policies, ...

Reclamation of abandoned farmland is crucial to a sustainable agriculture in arid regions. This study aims to evaluate the impact of different reclamation treatments on abandoned salinized farmland. We investigated four artificial reclamation treatments, continuous cotton (CC), continuous alfalfa (CA), tree-wheat intercropping (TW) and trees (TS), which were conducted in 2011–2012 in the Manasi...

Soil-water flow velocity can be a major factor affecting ion movement in the soil matrix. The transport of both cations and anions and their interactions with soil surface affect many aspects of soil management such as wastewater disposal, saline soil reclamation, remediation of sodic soils, and soil decontamination (HENG et al., 1999a). Therefore it is important to understand the processes tha...

This study describes the temporal and spatial variability of bacterial communities within a combined sewer system in England. Sampling was conducted over 9 months in a sewer system with intensive monitoring of hydraulic conditions. The bacterial communities were characterized by 16S rRNA gene-targeted terminal restriction fragment length polymorphism analysis. These data were related to the hyd...
