Changing chemistry and microbiology of reclaimed water as it is conveyed via reclaimed water distribution systems (RWDSs) can influence water quality at the point of use. Two simulated RWDSs comprised of 0.32-cm tubes (“Tube” RWDSs) and 10-cm diameter pipes (“Pipe” RWDSs) were designed to investigate how extremes in water age (32-min versus 5-d) and surface area to volume ratio (6.25 cm-1 versus 0

FT-ICR MS, NMR and ATR-FTIR were used to gain insight into the dissolved organic matter (DOM) removal process throughout a pilot water treatment system. The pilot plant under study utilises suspended ion exchange (SIX) followed by in-line coagulation with (ILCA) polyaluminium chloride and ceramic membrane filtration (CMF). MS results indicate that the SIX treatment is removing DOM irrespective of the

Lignite activated coke (LAC) has been modified in-situ by adsorbing the biodegradation effluent of super heavy oil wastewater (SHOW) to extract organic pollutants from raw SHOW before biodegradation is investigated. Results showed that, in comparison with LAC, modified Lignite activated coke (MLAC) exhibited a higher COD removal amount and adsorption capacity as with the increasing dosage. The modification

Sulfate reduction may inhibit methane production during anaerobic treatment of sulfate-containing wastewater. The purpose of this study was to establish direct interspecies electron transfer (DIET) between iron-reducing bacteria (IRB) and methanogens with Fe oxides to alleviate the inhibition of sulfate in anaerobic digestion. Effects of ferrihydrite on the digestion performances under various sulfate

Odor emitted during biosolids handling is a major issue for utilities and may pose serious nuisance to surrounding communities. The purpose of this study is to assess the effects of solids retention time (SRTs) of mesophilic anaerobic digesters on the odor emission from biosolids dewatered under various shear intensity and polymer doses. It was found that the digester SRT varying from 15 to 50 days

In a large-scale reverse electrodialysis (RED) system comprising several hundreds of cell pairs, the contribution of electrode resistance to total resistance is very small compared to that in typical electrochemical cells (e.g., fuel cell and battery). This feature indicates the low susceptibility to both electrocatalytic ability of the electrode and solution conductivity, and to the geometrical area

The hazardous consequences of radionuclide europium (Eu(III)) to humanity and ecological environment motivate the development of advanced sorbent materials for its efficient removal from wastewater. Herein, a flower-like molybdenum disulfide material fabricated with carbon composite (MoS2/C) was successfully prepared by situ hydrothermal method and confirmed by various experimental characterizations
