Micellar Enhanced Ultrafiltration (MEUF) of different phenolic derivatives including para-coumaric acid, vanillic acid, and tyrosol, in aqueous solutions has been studied. The MEUF experiments were conducted using an anionic surfactant, namely, Sodium Dodecyl Sulfate (SDS). Two polyethersulfone membranes with different molecular weight cut-off (20 kDa and 50 kDa) were used. Experiments were con...

Direct Capillary Nanofiltration (Direct CNF) is a new technique used for surface water and wastewater treatment in one step without pre-treatment. The CNF membrane module combines the favourable cleaning properties of capillary ultrafiltration membranes with the favourable separation properties of nanofiltration membranes in terms of removal of DOC, colour, bacteria, viruses and pesticides. Dir...

Geothermal conditions are extremely favourable in Hungary. Thermal water is accessible in 70% of the territory of the country, with a lowest temperature of 30°C. For energetic purposes, it can be utilized in two different ways: for supplying heat or generating electricity. In relation to utilization, one of the most serious problems derives from the chemical composition of thermal water. The pr...

BACKGROUND Phenol is one of the most versatile and important organic compound. It is also a growing concern as water pollutants due to its high persistence and toxicity. Removal of Phenol from wastewaters was investigated using a novel nanoparticle adsorption and nanofiltration technique named as Nanoparticle Assisted Nano Filtration (NANF). METHODS The nanoparticle used for NANF study were s...

The efficiency of Moringa oleifera (MO) seeds as a natural coagulant in the coagulation/flocculation process, followed by nanofiltration (NF) for the removal of cyanobacterial cells and cyanotoxins is investigated. "Synthetic water" prepared for the tests comprised de-ionized water with an inoculum of microcystis protocystis cells to obtain turbidity within the 50-450 NTU range. Methodology fol...
