A hybrid microfiltration–granular activated carbon system for water purification and wastewater reclamation/reuse
Microfiltration (MF) does not remove color, natural organic matter (NOM) or synthetic organic chemicals (SOCs). It must be combined with other conventional technologies such as activated carbo ...

... effect of MIEX®DOC water pretreatment on the performance of ultrafiltration membranes. The influence of MIEX® resin dose and membrane cut-off on natural organic matter removal (NOM) efficiency was analyzed. Based on obtained results it might be stated that magnetic ion-exchange resin MIEX® is ver ...

Natural organic matter (NOM) fouling in low pressure membrane filtration — effect of membranes and operation modes
The objective of this study was to evaluate the effects of operating modes, membrane materials and pore size on natural organic matter (NOM) fouling. A range of flat sheet microfiltration (MF) and ultrafiltration (UF) membranes were tested under conditions o ...

Fouling studies of a polyamide nanofiltration membrane by selected natural organic matter: an analytical approach
The present study compares the fouling properties of two selected and well-characterized hydrophobic (denoted HPOA) and hydrophilic (denoted TPIA) natural organic matters (NOM) fractions with a commercial polyamide (PA) nanofiltration (NF) membrane (denoted NF-55). Analytical tools such as elementa ...

... of 10 m3 h!1. Although the chosen process succeeded in producing water that met the demands for drinking water, the efficiency of the removal of natural organic matter was relatively low. Ultrafiltration (UF) and nanofiltration (NF) processes were investigated as alternatives and possible upgrade ...

... substances, model-solution with humic acid from Sigma-Aldrich GmbH and deionized water. The permeates and feeds in the case of modelsolution and natural well-water were analyzed measuring the UV absorbance on 254 nanometer. Based on the experiments, it can be established that the membranes with... (3.5 mg/L). The measured HS values showed a moderate increase with an increase in the NMWCO of the membranes. Keywords: Humic substances; Natural organic matter; Ultrafiltration; Nanofiltration; Membrane filtration; Disinfection by-products 1. Introduction Humic substances (HS) are natural material ...

The adsorption of trace contaminants on natural particles is of great interest as this adsorption enhances the possibility of removing these with low pressure filtration such as MF and UF. This... pressure filtration such as MF and UF. This study shows that natural hormones such as estrone and estradiol will adsorb to natural particles both organic and inorganic. Experiments have shown that the adsorption capacity of organics is a factor of 10 higher than for inorganics. Ultrafiltration of a... a dynamic membrane which enhances the retention of the hormones. Keywords: Ultrafiltration; Natural hormones; Endocrine disrupter; Natural organic matter; Water recycling; Membrane filtration 1. Introduction The fate of trace contaminants such as endocrine disrupters or pharmaceuticals in th ...
