In this paper, a numerical solution for the electro-osmosis consolidation of clay in multi-dimensional domains at large strains is presented, with the coupling of the soil mechanical behaviour, pore water transport and electrical fields being considered. In particular, the Modified Cam Clay model is employed to describe the elastoplastic behaviour of clay, and some empirical expressions are use...

The basic electro-kinetic process is defined by forced/induced movement of target pollutants in soil/sand medium under applied electric field low strength between electrodes of opposite polarities. There are several specific mechanisms that contribute to this movement of pollutants. However, one study suggested that the most important ones are electro-osmosis, electro migration, and electrophor...

Background and Objectives: Each patient has renal failure in any dialysis with high water volume, which is in direct contact with the patient's blood. The presence of any chemical and microbial contamination in water used in homodynamic devices can be very dangerous for these patients. The purpose of this study was to determine the efficiency of reverse osmosis open systems in improving the wat...

This paper describes a method to generate a concentration gradient using an osmosis-driven pump, without the need for bulky peripheral devices, such as an electric syringe pump or a pneumatic pump. By the osmosis, the flow in the microfluidic channel can be controlled even to a very slow speed (nanolitre scale), which enables its application to generate the stable and wide (width = 4 mm) concen...

The use of modern high flux reverse osmosis membranes with low salinity feeds at high recovery rates, makes the measurement of fouling by flux decline difficult in practice. Early detection of fouling is important, because the onset of fouling occurs at a critical flux which is difficult to predict a priori. An alternative method, measuring the electrical properties of the membrane is proposed ...

Membrane processes have been successfully employed for treatment of a large number of industrial effluents. Reverse osmosis (RO) and ultrafiltration (UF) are versatile separation and purification tools for the process industries. Both of these techniques are based on the ability of pressure-driven filtration membranes to separate multi-component fluids based on molecular size, shape, and chemic...

The present paper is a continuation of the series entitled "Equilibria in systems, in which the phases are separated by a semipermeable membrane," which have appeared in the proceedings of the Koninklijke Akademie van Wetenschappen (Amsterdam, Holland). In this paper I shall discuss in a simple form some of these results, viz. the osmosis of ternary liquids. The reader can find the thermodynami...
