Improvement of the Richardson-Zaki liquid-solid fluidisation model on the basis of hydraulics

Autor: J.P. van der Hoek, O.J.I. Kramer, P.J. de Moel, E.T. Baars, W.H. van Vugt, JT Johan Padding

Publikováno v: Powder Technology, 343

One of the most popular and frequently used models for describing homogeneous liquid-solid fluidised suspensions is the model developed by Richardson & Zaki in 1954. The superficial fluid velocity and terminal settling velocity together with an index

Publikováno v: International Journal of Multiphase Flow, 127

A novel effective drag relation for liquid-solid fluidisation is proposed, suitable for application in full-scale installations. This is achieved by presenting new insights related to the influence of the temporal-spatial heterogeneity on the effecti

Micronized CaCO3: a feasible alternative to limestone filtration for conditioning and (re)mineralization of drinking water?

Autor: W. J. C. van de Ven, J.C.J. Gude, F. Schoonenberg Kegel, P.J. de Moel, J.Q.J.C. Verberk, J.C. van Dijk

Publikováno v: Journal of Water Supply: Research and Technology-Aqua. 60:469-477

Worldwide limestone filtration is used in many treatment plants for the conditioning and (re)mineralization of drinking water to increase concentrations of Ca 2+ and HCO 3 − , pH and saturation index, thereby improving the quality of the water rega
