Selectivity parameters, needed for the BOHLM or BAHLM module design and their determination techniques, are analyzed. Selectivity can be controlled by adjusting the concentration, volume, and flow rate of the LM phase. Such control of the selectivity is one of the advantages of the bulk liquid membrane systems in comparison with other liquid membranes configurations and Donnan dialysis techniques. The idea of dynamic selectivity and determination techniques are presented and discussed. 

The performance of membrane processes also relies on the use of correct module configurations (Zhou Smith, 2002). Typical commercial manbrane geometries are flat sheet and mbular. There are five module types plate-and-flame and spiral-wound modules, based on flat membranes, and tubular, capillary and hollow-fibre modules, based on tubular membrane geometries (Basile, 2013). A qualitative comparison amongst some of the different model configurations is presented in Table 20.7.
