Ultrafiltration (UF) has been accepted as a versatile membrane separation process for water purification and wastewater treatment in recent years. In this paper the UF separation behaviour of oil-in-water emulsion used usually for metalworking fluids was studied. The effect was investigated of diffe

Fully submerged laboratory scale hollow fiber microfiltration module was used to treat a food industry wastewater in Malaysia. Permeate extraction was carried out continuously under a suction pressure not exceeding 0.9 bar. The module is aerated from beneath the microfiltration module to provide the

In this paper the results of an applied research project within the scope of the transfer centre 4031 funded by the German Research Foundation (DFG) are presented. In cooperation with the Henkel Genthin GmbH investigations have been made on the application of UF/NF membrane processes for the separat

This work is focused on the treatment of a textile plant wastewater. The industry mainly manufactures socks, stockings and panties, and the water is treated in order to be reused. The wastewater was characterized and jartests experiments were carried out with different coagulants and flocculants, at

The potential of using the integrated membrane system based on ultrafiltration (UF) and nanofiltration (NF) in purification of effluents from a cable factory was investigated. The UF experiments were performed using tubular membranes taking into consideration the composition of the treated effluents

The experimental results of the pilot scale application of different membrane technologies, supported by clariflocculation and ozonization, for textile wastewater reuse are described. The investigation has been carried out by treating two different textile effluents: a secondary effluent coming from

Several nanofiltration and tight ultrafiltration membranes were tested by mill-site filtrations using a DSS-Labstak M20-filter. Retention, flux and fouling were analysed. Membranes were also characterised by measuring contact angles and pure water permeability. These data were used to explain the ex

A landfill leachate treatment plant (LLTP) in Korea was retrofitted to improve treatment efficiency by using integrated membrane process that is composed of membrane bioreactor (MBR) and reverse osmosis (RO) process. In general, proper treatment of landfill leachate is difficult for its refractory c

A nanofiltration membrane has been developed by UV-photografting. Sodium p-styrene sulfonate was used for the modification of a polysulfone ultrafiltration membrane. The membrane cut-off was estimated. The grafted membranes have been evaluated for the removal of five different dyes with an aim to re

The pervaporation separation properties for the MTBE/C5/methanol ternary system and three corresponding binary mixtures were measured with a cellulose acetate membrane. It was found that there are very high pervaporation properties for methanol/C5 (the flux of methanol >430 g/m2.h). However, the flu
