The present study focuses on effects of operational parameters on electrochemical wastewater treatment for synthetic wastewater. Electro-oxidation has emerged as one of the advanced oxidation processes gaining more attention because it offers many distinctive advantages over other conventional methods such as versatility, high treatment efficiency, safety, amenability of automation and cost eff...

The objective of this research was to evaluate a magnetic ion exchange process (MIEX) for the removal of natural organic material (NOM) and bromide on a continuous-flow pilot-scale basis under different operating conditions and raw water characteristics. The most important operating variable was the effective resin dose (ERD), which is the product of the steady-state resin concentration in the ...

The aim of this study is to determine the impact upon dissolved organic matter (DOM) and removal of disinfection by-product (DBP) precursors of adding an ozone-biological activated carbon (O3-BAC) process after the conventional treatment process (CTP) using water from the Huangpu River in Shanghai, east China. Several metrics, including size fractionation, dissolved organic carbon (DOC) and tri...

This study investigates the effects of chlorothalonil (CLT) on chemical oxygen demand (COD) and dissolved organic carbon (DOC) in pilot-scale horizontal subsurface flow constructed wetlands (HSSFCW) planted with Phragmites australis. Physicochemical parameters of influent and effluent water samples, microbial population counting methods and statistical analysis were used to evaluate the influen...

This work aimed to characterize the coagulant properties of protein preparations from Moringa oleifera seeds in the removal of humic acids from water. Three distinct preparations were assayed, namely extract (seeds homogenized with 0.15 M NaCl), fraction (extract precipitated with 60% w/v ammonium sulphate) and cMoL (protein purified with guar gel column chromatography). The extract showed the ...

The Dissolved Organic Carbon (DOC) represents the largest organic carbon reservoir in ocean. Therefore, describing its spatio-temporal distribution is crucial for better understanding global cycle. Recent studies have demonstrated possibility to determine DOC coastal waters from ocean color radiometry (OCR) based on strong correlation with absorption coefficient of Colored Matter (acdom(λ)). Ho...

Background & Aims of the Study: One of the toxic pollutants in the wastewater of petrochemical industries is Terphetalic acid. In this study, the degradation and mineralization of Terphetalic acid in aqueous environment were studied by Ozonation and O3/ZnO processes in a semi batch reactor. Materials & Methods: This study is an experimental research on a laboratory scale. The st...

The aim of this deliverable was to look at ways and means to study biodegradable organic carbon removal during microbial growth at low nutrient concentrations. Emphasis was placed on both carbon removal and related biomass production. Three experimental setups are described in which these basic principles were studied. These are: (1) separate batch growth of a pure culture and a natural communi...

The objective of the research is to develop a new, simple, and environmentally friendly method for the simultaneous removal of heavy metals and total organic carbon (TOC) in coproduced water (CW) from the energy production industry. Ferrate anions (FeO4) or Fe(VI) oxidation ability is very strong over the whole pH scale. Fe(VI) has been considered one of the futuregeneration water quality impro...

The objective of this study was to assess whether the increase of NOM (natural organic matter) reported for natural waters in various countries could be observed for Suezenvironment water resources. Long term data for TOC, oxidability, colour, turbidity and other physico-chemical parameters were retrieved from 23 sites mostly in France (18), UK (3), Germany (1) and North America (1). Evolution ...
