Membrane contactor

In this paper, the viability of emulsion pertraction technology (EPT) for phenol recovery from the aqueous condensates obtained in the manufacturing of phenolic resins is described. This waste is highly concentrated in phenol (15–25 wt%) and formaldehyde (10–15 wt%). The experimental work was perfor

The aim of the study was to investigate the simultaneous removal of p -cresol and Cr(III) ions using a membrane contactor enhanced by a micellar solubilization. The investigations of solutes removal were performed taking advantage a polysulfone capillary membrane contactor in a counter-current mode

Relatively low and frequently changing flow rates and compositions in biohydrogen production require a highly efficient and low energy consuming gas cleaning technology to let this process become a competitive alternative in hydrogen production. Membrane contactors with non-porous polymeric membrane

The results of an experimental study, developed on a membrane bioreactor/membrane contactor pilot plant, aimed at drinking water denitrification are presented and discussed. In the adopted configuration the water, contaminated by nitrates, flows inside the fibres of a membrane unit. Due to the exist

A mathematical model has been developed to simulate the performance of an integrated extraction-stripping process based on the use of hollow fiber contactors. The model allows one to predict the time-dependent concentration profiles of the two phases involved in an individual extraction or stripping

In electrophoretic separators, a porous membrane is used to put into contact two flowing liquids between which an electrically driven mass transfer takes place. As far as charged solutes are concerned, the mass transfer can be affected by electrostatic interactions taking place at the membrane solut

This work focuses on a non-destructive process for recovering valuable aromatic fractions from an odorous tomato industry aqueous effluent. Non-dispersive solvent extraction of four selected aroma compounds, chosen as key aroma, was, at first, carried out on very diluted model aqueous solutions. Mas
