The results of concentration experiments on model dye solutions containing anionic surfactant and mineral salts were reported. The objective of the study involved recovery of valuable substances and water reuse. The membrane efficiency as well as dye and surfactant rejections during concentration te

The objective of the study was to compare the treatment efficiency obtained with the MIEX®DOC process and ultrafiltration as well as to investigate the effect of MIEX®DOC water pretreatment on the performance of ultrafiltration membranes. The influence of MIEX® resin dose and membrane cut-off on nat

Donnan dialysis with an anion-exchange membrane is proposed as a pretreatment step in a water desalination system. The process replaces anions that cause the precipitation of sediments with neutral chloride anions. Water after Donnan dialysis mainly contains soluble chloride salts that should cause

The objective of this study was to investigate the influence of MWCO, pressure, SDS concentration, salt amount and temperature on surfactant removal and permeate flux. Intersep Nadir membranes made from polyethersulphone (PES) and polysulphone (PS) were used. With the addition of a mineral salt to t

• T he investigations substantiated the thesis that t he hydrophilicity of the membranes noticea bly affects the efficiency of treating water p olluted with natural organic matter by u ltrafiltration. • S trongly hydrophilic membranes (made of r egenerated cellulose) displayed a high p ermeability a

The results of ultrafiltration removal of humic substances and metal ion admixtures from aqueous solutions have been presented. The membranes applied were made of sulfonated polysulfone. Transport and separation properties of the membranes in relation to model solutions have been investigated. In th
