Valorization of artichoke wastewaters by integrated membrane process

Recovery and concentration of polyphenols from olive mill wastewaters by integrated membrane system.

The purpose of this work was to analyse the potentialities of an integrated membrane system for the recovery, purification and concentration of polyphenols from olive mill wastewater (OMW). The proposed system included some well-known membrane operations such as microfiltration (MF) and nanofiltration (NF), as well as others not yet investigated for this specific application, such as osmotic di...

Valorization of Organic Wastes by Composting Process and Soil Amendment

Wastewaters from the olive-oil extraction process: disposal or valorization? Otpadne vode iz procesa ekstrahiranja maslinovog ulja: uklanjanje ili valoriziranje?

Olive vegetation waters (OVW) represent a serious environmental problem for the solution of which several disposal methods have been proposed, such as, e.g., physicochemical treatments (decantation with lime and/or total oxidation; concen-tration, drying and incineration; ultrafiltration and reverse osmosys), agronomic (acquaculture; landspreading) and animal-breeding methods (direct utilizatio...

Removal of surfactant from industrial wastewaters by coagulation flocculation process

Surfactants are among the most widely disseminated xenobiotics that contribute significantly to the pollution profile of sewage and wastewaters of all kinds. Among the currently employed chemical unit processes in the treatment of wastewaters, coagulation-flocculation has received considerable attention for yielding high pollutant removal efficiency. Jar-test experiments are employed in order t...

An Integrated Membrane Process for Butenes Production

Iso-butene is an important material for the production of chemicals and polymers. It can take part in various chemical reactions, such as hydrogenation, oxidation and other additions owing to the presence of a reactive double bond. It is usually obtained as a by-product of a petroleum refinery, by Fluidized Catalytic Cracking (FCC) of naphtha or gas-oil. However, an interesting alternative to i...
