Removal of Phenol From Wastewater by Different Separation Techniques
Application of membrane techniques (pervaporation and membrane-based solvent extraction) and adsorption to the removal of phenol from solutions modeling wastewater from phenol production by cumene oxidation process was investigated. The transport and separation properties of composite membranes PEBA, PERVAP 1060 and PERVAP 1070 in pervaporation of water-phenol mixtures were determined....

Change of the Performance Properties of Nanofiltration Cellulose Acetate Membranes by Surface Adsorption of Polyelectrolyte Multilayers
Surface modification of nanofiltration cellulose acetate CA membranes was carried out by alternating layer-by layer deposition of acidic chitosan CHI and sodium alginate ALG as the cationic and anionic polyelectrolyte, respectively. The pore size of the CA substrates monitored by the annealing temperature was determined from the retention values of...

Photochemical Modification of Membrane Surfaces for (Bio) Fouling Reduction: A Nano-Scale Study Using AFM
Biofouling, due to microbial growth on membranes, is a common problem during the operation of water treatment membrane plants. It leads to an increase in operation and maintenance costs due to the deterioration of membrane performance and ultimately shortening membrane life. In an attempt to develop membranes with lower fouling...

A Study on Producing Composite Nanofiltration Membranes With Optimized Properties
This paper attempts to produce nanofiltration membranes with varying properties through interfacial polymerization technique. The properties include pore size, effective charge density and effective membrane thickness. The ability to use NF membranes with varying properties will improve overall process efficiency as shown in previous study. The membranes produced were characterized...
