... amorphous silica membranes was proved with success. Experimental performance data was collected for more than 30 industrial relevant applications. Hybrid process design and optimization was carried out for the dehydration of isopropylalcohol. Even in this standard case a total cost reduction by 40 ...
Desalination 149 (2002)
A new hybrid gas separation process combining membrane permeation and pressure swing adsorption (PSA) is presented. An integrated model was formulated whic ...

Impact of coagulation conditions on the in-line coagulation/UF process for drinking water production
... dose induces an increase of the mass transfer resistance even in quasi-stable hydrodynamic operating conditions. Keywords: Water treatment; Fouling; Hybrid process; Coagulation; Ultrafiltration 1. Introduction Ultrafiltration (UF) membranes have rapidly become an efficient alternative to conventiona ...

... or adsorbents. Very good efficiency of residual COD removal and improvement in permeate flux may be obtained by coupling flocculation and MF. This hybrid membrane process might become the best solution for direct reuse of waste water or as a pre-treatment before a second step of RO. Desalination 14 ...

Denitrification of drinking water by the association of an electrodialysis process and a membrane bioreactor: feasibility and application
A hybrid process combining electrodialysis and a membrane bioreactor was investigated to treat ground waters with excessive nitrate concentrations.
Desalination 139 (2001)
This study focuses on an hybrid process which couples ultrafiltration and stripping. The aim is to treat spring water to disinfect it and to enhance its pH without addin ...
