Influence of operating conditions on ceramic ultrafiltration membrane performance when treating textile effluents
This work studies the performance of three commercial ceramic ultrafiltration membranes (ZrO2–TiO2) treating raw effluent from a textile industry. The effect of crossflow velocity at 3, 4 and 5 m s−1 as well as membrane characteristics, such as molecular weight cut-off (30, 50 and 150 kDa), on process performance were studied. Experiments were carried out in concentration mode in order to observe ...

Liquid-phase non-thermal plasma-prepared N-doped TiO2 for azo dye degradation with the catalyst separation system by ceramic membranes
This study strived to improve the photocatalytic activity by using liquid-phase non-thermal plasma (LPNTP) technology for preparing N-doping TiO2 as well as to separate/recover the N-dope TiO2 particles by using ceramic ultrafiltration membrane process. The yellow color N-doped TiO2 photocatalysts, obtained through the LPNTP process, were characterized with UV–Vis spectroscopy, X-ray diffraction ...

From fermentation residues to nutrient concentrate
Treatment of fermentation residue substrates from biogas plants by means of ceramic membranes The growing number of biogas plants makes it increasingly difficult to return the fermentation residue substrates to green spaces or arable land. Especially large-scale plants are often unable to find sufficient disposal possibilities in acceptable distances. Therefore it is sensible to treat ...

From fermentation residues to nutrient concentrate
The growing number of bio-gas plants makes it in-creasingly difficult to return the fermentation residue substrates to green spaces or arable land. Especially large-scale plants are often unable to find sufficient disposal possibilities in acceptable distances. Therefore it is sensible to treat fermentation residue substrates by suitable screening processes in such a way that they can be ...

Ceramic membrane ultrafiltration of natural surface water with ultrasound enhanced backwashing
Ultrafiltration membrane cleaning with ultrasound enhanced backwashing was investigated with two ceramic membrane systems in parallel. One of them was subjected to ultrasound during backwashing, the other acted as a reference system. The feed water was directly taken from a creek with a sedimentation process as only pre-treatment. The cleaning performance was improved with ultrasound but after 3 ...

UF Membrane Technology
Ultrafiltration (UF) is a variety of membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane. High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). The pore size of the ultrafiltration ...
