Modelling

There has been an increasing interest in a new technique for making emulsions known as membrane emulsification, which uses a microporous membrane operated in cross-flow. The continuous phase is pumped along the membrane and sweeps away dispersed phase droplets forming from pore openings as shown in

A theoretical study is developed for the modelling of mass accumulation from the polarised layer to the formation of a deposit. Concentrated suspension properties are accounted for through a solid pressure corresponding to osmotic pressure in the suspension and to compression resistance in the depos

A big problem for the desalination plants situated far from the sea is the elimination of the concentrated brines. The volume reduction of the final concentrate could allow an economic transport and a high recovery level. In order to solve this problem, a reverse osmosis system with recirculation (R

Different flow sheets for thermal desalination processes were simulated using the computer program Evapolund. This general software is modular in structure and includes a number of modules describing different components in an evaporation process such as evaporators, different types of heat exchange

T he presented study demonstrates that the outlined modelling concept for membrane bioreactors could successfully be applied to describe the system behaviour of a pilot-scale wastewater t r e a t m e n t plant, e q u i p p e d with m e m b r a n e f iltration units. In particular, the model describi
