Removal of natural organic matter from aqueous solutions by electrocoagulation
Natural organic matter (NOM) affects some qualitative parameters of water such as color. In addition, it can deteriorate the performance of water treatment process including coagulation, adsorption, and membranes. NOM also reacts with chlorine in the chlorination process and may form disinfection by-products. The present study was carried out in laboratory-scale in a batch system using a cylind...
متن کاملEvaluation of a Disc Tube Methodology for Nano- and Ultrafiltration of Natural Dissolved Organic Matter (DOM)
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...
متن کاملRemoval of natural organic matter by ultrafiltration with TiO2-coated membrane under UV irradiation.
This study investigates the performance of ultrafiltration (UF) by membranes coated with titanium dioxide (TiO2) photocatalyst under ultraviolet (UV) illumination in removing natural organic matter (NOM) and possibly in reducing membrane fouling. Experiments were carried out using heat-resistant ceramic disc UF membranes and humic acids as model substances representing naturally occurring organ...
متن کاملUltrafiltration of natural organic matter from water by vertically aligned carbon nanotube membrane
In this study vertically aligned carbon nanotubes (VA-CNT) was grown on anodized aluminum oxide (AAO) substrate. The synthesized AAO-CNT membrane was characterized using Raman spectroscopy, field emission scanning electron microscopy (FESEM), contact angle and BET. The pure water flux, humic acid (HA) (as representative of natural organic matters) rejection and fouling mechanism were also evalu...
متن کاملVoltammetric Investigations of Natural Organic Matter
Redox activity is one of the most important, and yet poorly understood, properties of natural organic matter (NOM). It is well known that NOM can act as a reducing agent (reductant), and this is central to the role that NOM plays in the biogeochemical cycling of carbon. More recently, there has been growing interest in the role that NOM plays as an electron shuttle (mediator) in biogeochemical ...
