This report summarizes the findings of an evaluation of the cross-flow pervaporation technology developed by ZENON Environmental, Inc. (ZENON). This evaluation was conducted under the U.S. Environmental Protection Agency (EPA) Superfund Innovative Technology Evaluation (SITE) Program. The ZENON pervaporation technology was demonstrated over a 5-day period in February 1995 at Naval Air Station N...

Flavor and odor components of foods are often lost during processing, which leads to a final product with poorer quality when compared to fresh made ingredients. It is not a different scenario in orange juice and other beverage industries. Heating processes cause severe physical and chemical losses of the natural characteristic flavour of orange juice. Methods, that use lower heat, present ther...

Nanopore silicalite type membranes were prepared on the outer surface of a porous-mullite tube by in situ liquid phase hydrothermal synthesis. The hydrothermal crystallization was carried out under an autogenously pressure, at a static condition and temperature of 180 °C with tetrapropylammonium bromide (TPABr) as a template agent. The molar composition of the starting gel of silicalite zeolite...

As a well-known one-atom thick nanosheets with preeminent physicochemical properties, graphene and its derivatives (e.g., graphene oxide, GO) have shown great potential on the membrane separation filed. This paper presents an update of GO laminates developments, including the membrane preparation methods, physicochemical properties and water vapor transport of GO laminates, and their applicatio...

Broomcorn seed (Sorghum vulgare) was used as raw material for bioethanol production. Optimum conditions were obtained from response surface method. Broomcorn seed flour (45 g/l) was treated by alkaline treatment and dual enzymatic hydrolysis (0.7 g/l of α- amylase and 0.42 g/l of amyloglucosidase). The hydrolyzed total sugar of 25.5 g/L was used in conventional bioethanol production (8.1 g/l) u...

Highly efficient PDMS based membranes with a new type of fluorinated MOF-808 were successfully prepared and used for the first time in pervaporation (PV). Two types ligands i.e. trifluoroacetic acid (TFA) pentafluoropropionic (PFPA) during MOF synthesis. These slightly different size chemical character influenced material properties membranes, roughness, contact angle, surface free energy, ther...
