Sugarcane green ceramic hollow fibre membrane for oily wastewater separation
… work describes the preparation of green ceramic hollow fiber membranes derived from waste sugarcane bagasse ash (WSBA) using phase inversion and sintering techniques. The first step in the production of WSBA was the calcination process of sugarcane bagasse at 800 °C followed by characterization …

Studies On Copper Extraction With Hydroxyoxime Extractants For The Design Of Hollow Fibre Membrane Based Extraction Processes
… technique consisting of a microporous hollow fibre module was used in this study to examine the mass transfer properties of the extraction and stripping processes of copper across an immobilised interface system. The extraction and re-extraction (stripping) processes in this system were …

Zur Frage der Stofftransporteigenschaften von Oxygenatorhohlfasermembranen bezüglich der Durchlässigkeit für Fluide und Narkosegase
Microporous hollow fibre membrane oxygenators with clinically-established polypropylene (PP) or innovative polymethylpentene (PMP) membranes are used clinically for cardiopulmonary bypasses (CPB) and extracorporeal life support (ECLS). Membrane oxygenators with silicone plates may also be used. …

Theoretical and experimental investigation of membrane distillation
Invented in the 1960s, membrane distillation is an emerging technology for water treatment attracting more attention since 1980s. There are four configurations of membrane distillations including air gap membrane distillation (AGMD), direct contact membrane distillation (DCMD), sweep gas membrane …

Removal of arsenic from water using adsorption on alumina/membrane separation.
… of adsorbent particles from the liquid phase via membrane separation, and regeneration of the adsorbent. The effect of process parameters such as pH, residence time, adsorbent characteristics, presence of competing ions, and initial arsenic concentration were studied. A number of commercially …

Membrane Fouling Mitigation with Water Hammer
Membrane technology has proven to become a prolific separation technique in many industries. However, its widespread application has been limited by fouling. Fouling results in a decline in membrane performance and requires regular chemical cleaning to sustain the operation. This thesis focuses on …

Comparison of two ultrafiltration membrane systems for whole milk feta cheese production : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Food Technology at Massey University, Auckland, New Zealand
… method of feta cheese production involves a membrane filtration method, known as ultrafiltration. The ultrafiltration process utilises pressure as a driving force to concentrate milk by removal of water and small dissolved molecules. Hollow fibre and spiral wound ultrafiltration membranes are …
