The paper presents a mathematical model of rocks freezing saturated with salt solution under impact of osmotic force. Osmosis is related to the salt concentration gradient, which is characteristic for solutions, and it is a powerful mechanism for the movement of solutions in poorly permeable porous...

Freezing patterns in a porous soil saturated with a saline solution are investigated with regard to osmotic effects, using a model suggested previously by the authors but in a more general formulation. The results include a numerical and an approximate self-similar analytical solution to a nonlinear...

Possible aspects of development of livestock business of the Republic of Kalmykia in interrelation with deficiency of water in the region are shown. A schematic diagram of local installation of water purification is considered. Economic, ecological and technological advantages are shown.

A rule-based control is presented for desalination plants operating under variable, renewable power availability. This control algorithm is based on two sets of rules: first, a list that prioritizes the reverse osmosis (RO) units of the plant is created, based on the current state and the expected w...

This article focuses on the mechanisms likely to generate salt flux towards the aquifer environment from a cavity created by dissolution within a layer of salt under clay cover, until causing its collapse. This problem is encountered by salt operators, particularly in Lorraine, who exploit a salt de...
