May 01 2003 It was found that poly12-dimethyl-5-vinylpyridinium methyl sulfate-co-N-vinylpirrolidone promotes the formation of dense flocs and provide a complete sedimentation of the kaolin suspension at a high rate. The effect of dense floc formation is likely caused by a copolymer hydrophobicity and a compression of adsorbed macrocoils accompanied by squeezing of a dispersion medium out of

Sep 22 2003 The present work deals with the estimation of average floc diameter using sedimentation and optical data. This study was applied to a kaolin suspension destabilized by chemical dosing with iron salts FeCl 3 or FeSO 4 or electrocoagulation EC with iron electrodes. Optimum pH and coagulant concentration were defined by turbidity measures on destabilized suspensions.

Determination Of The Fractal Dimension Of Microbial Flocs
Determination Of The Fractal Dimension Of Microbial Flocs

The fractal dimension is of ultimate importance in the description of the properties and behavior of microbial flocs in biological wastewater treatment systems. However the methods for the measurement of the fractal dimension have not been well-established. In this study a new method is developed to determine the fractal dimension of biological flocs in activated sludge AS suspensions.

Monitoring And Characterisation Of Sandmud Sedimentation

May 25 2016 Estuaries and tidal inlets are often characterised by the presence of both cohesive and non-cohesive sediments. Knowledge of the sedimentation behaviour of sand-mud mixtures is therefore crucial to the understanding and prediction of the time-dependent structure i.e. mixed or segregated composition and erodibility of sediment bed deposits developing within these environments.

What Is Sedimentation Yahoo Answers
What Is Sedimentation Yahoo Answers

Jan 05 2014 In geology sedimentation is often used as the polar opposite of erosion i.e. the terminal end of sediment transport. In that sense it includes the termination of transport by saltation or true bedload transport. Settling is the falling of suspended particles through the liquid whereas sedimentation is the termination of the settling process.

Sedimentation Volume Is A Ratio Of The Final Or Ultimate
Sedimentation Volume Is A Ratio Of The Final Or Ultimate

Here the sedimentation depends not only on the size of the flocs but also on the porosity of flocs. In flocculated suspension the loose structure of the rapidly sedimenting flocs tends to preserve in the sediment which contains an appreciable amount of entrapped liquid. The volume of final sediment is thus relatively large and is easily redispersed by agitation.
