Simulated values for the total retention rate coefficient and the maximum solid phase concentration of Ag-ENPs increased with increasing solution ionic strength, cation valence, clay and silt content, decreasing flow velocity, and for polymer-instead of surfactant-stabilized Ag-ENPs.
This column performance theory is developed to calculate the maximum solid phase concentration of the solute on an adsorbent and the adsorption rate constant for continuous adsorption process in column studies (Malkoc and Nuhoglu 2006; Han et al. 2007).
The Thomas kinetic model was used to calculate the data obtained in continuous fixed-bed systems for obtaining maximum solid phase concentration of TC on adsorbents and the adsorption rate constant [33].
As the retained concentration of species 1 approached the maximum solid-phase concentration, a second mobile species (species 2, i.e., the same PVP-AgNPs that are reversibly retained) was released that could be retained at a different rate than species 1 and thus yielded the nonmonotonic RPs.
The fixed-bed column data were fitted to the Thomas model to determine maximum solid-phase concentration (q Th).
One of the main objectives of wine grape growers in several viticultural areas throughout history has been the achievement of full ripening, i.e. maximum soluble solids concentration in the absence of apparent berry shrinkage.
The Ne abundance (dash-dot, red) displays a peak at around 23:10 h (AST) that coincides with the Na concentration maximum (solid line, left ordinate).
It has been found that, for the different gas/activated carbon slurry systems studied in the literature, a remarkable similarity exists in the maximum achievable enhancement factor and the minimum solids concentration needed to reach the maximum enhancement.
However, experience shows that existing mathematical models underestimate dewatering in thickeners for flocculated feed materials when predictions are made of either the underflow solids concentration for a given solids feed flux density or the maximum solids feed flux density achievable for a minimum underflow solids concentration set point.
