Interfacial effects in solid‐liquid separations. In this survey the nature and origin of interfacial effects in finely dispersed suspensions are explained. Their influence upon conventional process steps in solid‐liquid separation is discussed. Examples of technical applications of electrokinetic effects in separation processes are reviewed. The state‐of‐the‐art in solid‐liquid separation is characterized by qualitative knowledge about the effects of interfacial phenomena and empirically based electrokinetic separation processes. Knowledge is still insufficient for quantitative calculation of real processes or proper design of technical equipment. The field between interfacial physics, physical chemistry of surfaces and chemical or process engineering is interesting and far‐reaching. If the preceding step of particle generation by precipitation or crystallization is included in a comprehensive research program, a better understanding and a systematic use or prediction of electrokinetic interfacial phenomena in solid‐liquid systems can be expected.
