Ceramic membranes

The presence of fine solids and dissolved organics in produced water from Steam-Assisted Gravity Drainage (SAGD) process can potentially block pressure vessels and cause fouling and corrosion in steam boilers. Ceramic membranes in tubular configurations with pore sizes of 20 kDa, 50 nm and 100 nm were

Nanoscale iron oxide particles were synthesized and deposited on porous alumina tubes to develop tubular ceramic adsorbers for the removal of arsenic, which is an extremely toxic contaminant even in very low concentrations. In addition, its natural presence affects rural and low-income populations i

The study shows the results of studies concerning the hydraulic permeability of ultrafiltration and hybrid in-line coagulation–UF (without sedimentation) systems during the treatment of water containing higher concentrations of organic matter. The calculation of UF permeability was made employing a

The reduction in permeate flux caused by fouling is a drawback in the operation of membrane systems that can be alleviated using mechanical and electrical methods. Alternatively, physicochemical treatments provoking the elimination of fouling agents have been proposed as effective strategies for the

Goat milk shows interesting similarities in comparison with human milk in terms of their oligosaccharides composition, which suggests that goat milk oligosaccharides could mimic the physiological activities described for human milk oligosaccharides. However, the supplementation of the accompanying g

This paper describes the manufacture of tubular ceramic membranes and the study of their performance in the demulsification of soybean oil/water emulsions. The membranes were made by iso-static pressing method and micro and macro structurally characterized by SEM, porosimetry by mercury intrusion an

Separation efficiency of ceramic NF membranes manufactured by Tami Industries (Nyons, France) is investigated for the separation of aqueous solutions containing strong inorganic electrolytes. The membrane used is multi-layer structured with a mixed titania and zirconia selective layer (1000 Da MWCO)

The results of microfiltration studies using inorganic TiO2/Al2O3 membranes for solutions containing yeast are reported. The aim of the research was experimental as well as mathematical analysis of the permeate flux dependence on time for cross-flow filtration combined with backflushing using permea

The results of microfiltration (MF) studies using ceramic 150 kDa membrane and model solutions containing bovine serum albumin (BSA) with and without NaCl as well as salted wastewater from fish industry are reported. The aim of the research was experimental analysis of operating parameters enabling

Desalination of seawater and NaCl solutions is of great interest as potable water sources are dramatically declining on earth. Most of the techniques used to decontaminate water involve polymeric membranes and expensive desalination processes. To improve thermal, chemical and physical resistance of
