The study shows the results of studies concerning the hydraulic permeability of ultrafiltration and hybrid in-line coagulation–UF (without sedimentation) systems during the treatment of water containing higher concentrations of organic matter. The calculation of UF permeability was made employing a

This study focused on the removal of toluene from the wastewaters of the chemical industry. The tests were carried out on a polydimethylosiloxane (PDMS) membrane filled with carbon black (PDMS'/cb) and another without the filling (PDMS). It was confirmed, that the addition of the hydrophobic filling

The increasing contamination of soil and waters with volatile organic compounds, such as halogen derivatives or petrochemical hydrocarbons, poses a serious hazard due to the carcinogenic effect of most of the compounds. Their low concentrations as well as the presence of other hindering substances m

One of the methods of achieving high selectivity or high flux for specific compounds is the modification of membrane such as filling, grafting or coating. The most common is adding fillers, especially high aspect ratio fillers. It improves physical properties such as increased stiffness or reduced c

(1) Coagulation applied, as a unit process does not caused full reduction of organic compounds, and therefore it cannot be applied as a single unit process in the treatment of water containing NOM. (2) Analyzing the results involving the unit process (ultrafiltration) we found high efficiency of tur

The study was aimed at removing organic solvents from aqueous solutions using pervaporation. The tests were carried out on a composite polydimethylsiloxane (PDMS) membrane manufactured by GKSS/ Forschungszentrum Geesthacht, Germany and a polydimethylsiloxane membrane filled with carbon black (PDMS +

The results of studies are presented on the treatment of natural waters with a high content of organic compounds. The research involved unit processes of coagulation, microfiltration, and the hybrid process coagulation– sedimentation–microfiltration. In the membrane filtration process 19-channnel ce

Studies were carried out on the treatment of water for potable purposes using ceramic and capillary membranes. The studies involved the processes of unit microfiltration and ultrafiltration as well as hybrid processes. In the hybrid processes, adsorption on activated carbon and membrane separation w

Environmental transformations caused by the economic human activity generate rapid changes in surface water quality. The application of activated carbon in conjunction with microfiltration/ultrafiltration processes is an emergency technology for the removal of organic compounds from water for consum

The paper presents the investigations concerning membrane treatment of water containing chloroform. Reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) techniques were applied. Removal degrees of chloroform and flux drop during membrane filtration were determined. Basing on the result
