Experimental studies of kinetic coefficient of reverse-osmosis solute partitioning with saline metals

Annotation

The results of experimental researches on rejection coefficient and specific flow solvent, showing that with the growth of barometric gradient the motivation of the studied process is growing leading to that the specific flow and coefficient is increasing with the pressure rise. At the densification of dissolved solids in the solution the specific flow is descending because the osmotic pressure of solution is increasing and as a rule the viscosity and solution density. The estimated coefficient interception of the dissolved solids by membrane with the increase of concentration is connected with the formation of three characteristic periods in separative power of membrane.
