Hollow fibres

This work focuses on vacuum membrane distillation (VMD) for seawater desalination. The aim of the work was to compare twohollowfibre module configurations (inside/out and outside/in). Experiments were carried out with pure water and with 15 g/L up to 300 g/L NaCl solutions... in). Experiments were carried out with pure water and with 15 g/L up to 300 g/L NaCl solutions and for two different material and structure offibres. Pure water permeability and global heat transfer coefficient were compared for the two configurations. The influence of hydrodynamics on globa...

A laboratory-scale study was carried out to evaluate the feasibility of a combined process of coagulation-flocculation with filtration throughhollow-fibre membranes as tertiary treatment of the effluent of a conventional activated sludge plant. The Aluminium Polychloride (AlP) was tested as... From the economical and technical point of view, the optimal concentration is 10 mg/l of AlP.
