Abstract

Objective: This paper describes examples of membrane engineering for water that take inspiration from biology. Next generation, high permeability, desalination membranes incorporating natural Aquaporin water channels are described. A potential consequence of raised flux is boundary layer mass transfer limitation which can be alleviated by unsteady shear stress, such as vibrations, adopted by some aquatic species to improve respiration. In many applications, biofilms on membranes cause detrimental biofouling. Keywords: Desalination, aquaporin, membranes, biofilms, water applications, mass transfer.
