Computational Fluid Dynamics Modelling of Flocculation in Water Treatment: A Review [PDF]
, 2009 The principal focus of this paper is to present a critical review of current approaches to modelling the inter-related hydrodynamic, physical and chemical processes involved in the flocculation of water using Computational Fluid Dynamics (CFD).

The flocculation of kaolin with polyacrylamides [PDF]
, 1982 Flocculation occurs when high molecular mass organic molecules form bridges between particles, causing them to aggregate. This modifies the sedimentation properties of the mineral slurry.

FLOCCULATION VALUE OF MINERAL WATERS. [PDF]
, 1951 Flocculation value of 24 mineral waters was measured with colloidal solution of iron hydroxide. There exists a negative correlation (r=-0.72, Fo=(r(2)(N-2))/(1-r(2)) =21.6 >F=8.10 n1=1 n2=20 α=0.01) between the logarithms of sulfate ion concentration of ...

Evaluation of the Efficiency of Bio-Polymers Derived from Desertic Plants as Flocculation Agents
Chemical Engineering Transactions, 2016 In the treatment of wastewater, flocculation is one of the most used processes, which aims to eliminate colloidal particles cannot be removed by other methods; Traditionally it has been used aluminum or iron salts and synthetic polymer, which generate ...

Phosphorus removal by microelectrolysis and sedimentation in the integrated devices [PDF]
Archives of Environmental Protection, 2021 This paper presents the results of tests performed on an installation with an aerated microelectrolytic bed (MEL-bed) and sludge sedimentation. The systems were designed in two versions, differing in the aeration method, i.e., a mechanically aerated ...

Selective flocculation of iron oxide-kaolin mixtures using a modified polyacrylamide flocculant
Bulletin of Materials Science, 1988 High molecular weight polyacrylamides were synthesized and successfully modified to contain up to 8·3% hydroxamate functional groups. The selective flocculation tests carried out on 1:1 iron oxide/kaolin mixtures using parent polyacrylamide, polyacrylic acid and the modified polyacrylamide, confirm the possibility of enhancing selectivity through ...
