TL;DR: In this article, the authors present the principle and theoretical basis for application of electrochemical impedance spectroscopy (EIS) to study ion transport and partitioning in thin films or membranes supported by a solid electrode and exposed to an electrolyte solution.

TL;DR: It is asserted that the two types of antiscalant induce biofilm formation on RO membrane surfaces through two different mechanisms: while polyacrylates increase bacterial initial attachment by altering membrane physico-chemical properties, mainly increasing membrane hydrophobicity, polyphosphonates increase biofilm growth under phosphorous limiting conditions by providing the cells with the phosphorous they lack.

TL;DR: In this article, an experimental study of ion transport in polyamide selective layer of composite reverse osmosis and nanofiltration membranes by means of electrochemical impedance spectroscopy (EIS) is presented.

TL;DR: A procedure is proposed that reduces filtration data to two general phenomenological coefficients, concentration-dependent salt permeability omega(s) and Peclet coefficient A, which does not require that a specific exclusion mechanism be assumed and thus allows a transparent test on consistency with commonly used models.
