Hydro Chemicals

In the present time our organosilicon adsorbents found the practice application in such as fields such as, for example 1) the method of spectral-chemical determination of gold Clarke quantities in poor ores and rocks has been applied in analytic practice of geological establishments and research institutes 2) at the first time soi ption process was used in hydro-chemical analyze of fresh water. This method has been allowed to analyze of Baikal water 3) for purification metallurgical waters and waste solutions of chemical-metallurgical plants due to toxic elements 4) for creation the filters for extraction of rare elements, for example, uranium 5) for silver utilization from wasted of cinema-photo manufactory. This method has been applied to obtain the silver of high purity.

To prevent from hydro-chemical clogging the systems should be designed so there is no entrance of air to the ground water loop. Hence, the loop should be perfectly air tight and constantly under pressure. 

Hydrological and hydro chemical regimes of the delta and especially of the liman are mainly determined by the river fresh water inflow, local climatic conditions, including wind regime, and water exchange between the liman and the sea through the outlet. 

A layer of coexistence of oxygen and hydrogen sulfide (C-layer) was observed in the earliest hydro chemical studies in the Black Sea, and it was assumed that oxidation of hydrogen sulfide takes place mainly by oxygen reaction within this layer [23-26]. During the RV Knorr 1988 expedition, it was found that oxygen concentrations measured with the Winkler technique were significantly lower than found earlier [16,27]. This fact of absence of... 

The rate of calcite dissolution is known to depend on the hydrodynamic conditions of the environment and on the rate of heterogeneous reaction at the mineral surface. Numerous laboratory studies demonstrate transport and surface-controlled aspects of calcite reactions in aqueous solutions, but until recently, no study has been comprehensive enough to enable comparison of kinetic results among differing hydro-chemical systems.

Damage mechanics principles have been applied extensively for well stability problems, especially for hard, brittle and fractured shale rocks. Constitutive models using damage concept, coupled with hydro-chemical swelling models, have been developed based on experimental results, and applied for design of drilling fluid density, combined with FEM methods (Liu, 1995).
