Red wine contains many compounds which have a beneficial effect on human health. The aims of this study were to concentrate the valuable components of wine by nanofiltration, to describe the mathematical model of the permeate flux and to estimate the cost of the process. Laboratory-size equipment wi

This article deals with water removal from oil-in-water emulsion by an ultrafiltration membrane at different transmembrane pressures. The membrane intrinsic resistance and gel resistance are analyzed and determined based on the resistance-in-series theory. The experimental results show that the effe

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

In this study the removal of humic substances from model-solution and well-water using four different ultrafiltration membranes has been investigated. The permeates were analysed by UV254nm absorbance, TOC and DOC measurements. Based on our experiments it can be established that the examined membran
