Constructed wetlands are commonly used to treat domestic wastewater, but the extent which microplastics retained in constructed and impact this has on their efficiency not known. In context, we investigated retention of (microbeads fibres) effects removal carbonaceous (expressed as chemical oxygen demand (COD), biochemical (BOD5), dissolved organic carbon (DOC)), nitrogenous (N-NH4+, N-NO3-, N-...

a floating polymer-supported photocatalyst based on polystyrene impregnated with titaniumdioxide particles was developed using a facile solvent-cast method at ambient temperature. the preparedphotocatalysts were characterized by x-ray diffraction, scanning electron microscopy and fourier transforminfrared spectroscopy. the photocatalytic activity of the developed photocatalysts was investigated...

The degradation of iprodione (IPR), a once frequently used but recently banned dicarboximide fungicide, by UV-C light-, zero-valent iron- (ZVI), and aluminium (ZVA)-activated persulfate (PS) oxidation processes was comparatively studied in distilled (pure) water (DW) simulated, tertiary treated urban wastewater (SWW). performance PS-activated examined following IPR (2–10 mg/L) removal, PS (0.01...

The performance of a disc tube (DT) methodology, originally designed for reverse osmosis (RO) in desalination, and applied here for ultrafiltration (UF) and nanofiltration (NF) of dissolved organic matter (DOM) in a set of fresh (0 ppt), brackish (10 ppt) and saline (30 ppt) waters at low (1 2 mg/L), medium (5 6 mg/L) and high (10 12 mg/L) dissolved organic carbon (DOC) content is presented. Th...

Understanding the complexity of dissolved organic matter (DOM) in stormwater has drawn a lot of interest, since DOM from stormwater causes not only environmental impacts, but also worsens downstream aquatic quality associated with water supply and treatability. This study introduced and employed high-performance size exclusion chromatography (HPSEC) coupled with an ultraviolet-visible (UV-vis) ...

The raw water of water treatment works ‘the Blankaart’ (Belgium) is characterized by high levels of NOM and alkalinity. From 2006 until present, the possibility of applying fluidized ion exchange for NOM removal at the Blankaart plant has been investigated. Although the efficiency of ion exchange with respect to NOM removal has already been demonstrated by numerous studies on a wide range of ra...

Background: Natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (DBPs) and membrane fouling during water filtration. In this study, the performance of the peroxi-electrocoagulation process (PEP) was investigated for the removal of humic acids (HAs) from aqueous solutions. Methods: PEP was carried out for the remov...

UV treatment is a cost-effective disinfection process for drinking water, but concerned to have negative effects on water quality in distribution system by changed DOM structure. In the study, the authors evaluated the effects of UV disinfection on the water quality in the distribution system by investigating structure of DOM, concentration of AOC, chlorine demand and DBP formation before and a...
