The presence of turbidity and precipitates in the bottle causes depreciation wine by consumers. Colloidal instability is at basis these phenomena. cold treatment a technique widely used to stabilize wines, as regards both tartaric colloidal precipitations. However, it an energy-consuming technique. In view sustainable management winery practices, work aimed evaluating possibility using some eno...

Bentonite with fine components much such as extremely expansive soil has been commonly required buffer/backfill materials in order to prevent seepage for construction of further deep geologicalrepository disposal high-level radioactive waste (i.e. HLW). The buffer received significant hydromechanical efforts from host rock at underground environment. While the construction/maintenance long-time...

This experiment was conducted to study the effects of two kinds of sodium and calcium bentonite (NaB and CaB) on performance, blood biochemical parameters, carcass characteristics and tibia ash of broiler chickens. Two hundred and sixty day old broilers of male Ross 308 strain were allocated to 5 treatments with four replicatates and 13 broilers in each. The experiment was carried out in a comp...

The interaction between bentonite and tylosin was investigated in broiler chickens, based on pharmacokinetic characteristics obtained in vivo. Simultaneous oral administration of bentonite and tylosin significantly lowered plasma levels of tylosin and reduced the area under the plasma concentration-time curve (AUC(0-inf)), maximal plasma concentration (C(max)), time to maximal plasma concentrat...

Bentonite is a native, colloidal, hydrated aluminum silicate. It occurs as a very fine, odorless, pale buff or cream-colored powder, free from grit, and has a slightly earthy taste. Although it is insoluble in water, it swells to approximately 12 times its volume when added to water. Bentonite magma is prepared by adding 50 gm. of bentonite to a sufficient quantity of purified water to make 1 l...

The influence of bentonite additions and soil K status on radiocaesium transfer to ryegrass was investigated in a potted soil experiment. A sandy soil was contaminated with I M Cs and amended with K salts (0-97 mM kg") and K bentonite (0-2 %). After 4 weeks incubation of the mixtures, ryegrass was grown for 18 weeks and trimmed at 7 occasions. During subsequent harvests, the radiocaesium transf...

This study investigated the combined effect of temperature and single-species salt solutions on geotechnical properties (swell index and liquid limit) and hydraulic conductivity of bentonite applying different cation types, concentrations, and temperatures. Results showed that both the swell index and the liquid limit decreased with an increase in salt concentration irrespective of the type of ...

Bentonite with its unique structural properties is a valuable material for environmental application. Its sorption properties are usually improved by the different ways of modification. In this work, the special sedimentation method was used for the treatment of the natural bentonite to obtain monomineral fraction of montmorillonite. The modification by iron oxide particles was used with the ai...

This paper summarises the results of radon diffusion coefficient measurements in 360 common waterproof materials available throughout Europe. The materials were grouped into 26 categories according to their chemical composition. It was found that the diffusion coefficients of materials used for protecting houses against radon vary within eight orders from 10(-15) to 10(-8) m(2) s(-1). The lowes...

An intensive study has been made to see the performance of the different liner materials with bentonite on the removal efficiency of Cu(II) and Zn(II) from industrial leachate. An artificial neural network (ANN) was used to display the significant levels of the analyzed liner materials on the removal efficiency. The statistical analysis proves that the effect of natural zeolite was significant ...
