The high volume and unfavorable properties of high-water-content slurries make their treatment difficult costly. Improving the through prefabricated drains combined with surcharge or vacuum preloading represents an environmental economic means reusing these as subsoil. As conventional methods are inefficient in dealing low-permeability slurries, flocculation is often applied. In this study, inf...

Small particles typical of liquid swine manure often clog sand filter beds and fine filters. We evaluated the effectiveness of polymer flocculants to improve drainage and filtration performance of sand filter beds by increasing the particle size of manure. A pilot separation unit was evaluated at the Swine Unit of the NCSU Lake Wheeler Road Laboratory in Raleigh, North Carolina, in 40 consecuti...

The effect of the degree of polymer branching on retention and drainage performance of flocculated kraft pulp fiber suspensions containing precipitated calcium carbonate (PCC) was investigated and has been correlated with flocs properties obtained by light diffraction scattering (LDS). The results show that polymers of medium charge density are more adequate to be used as retention aids since l...

flocculation processes during estuarine mixing can reduce the elemental concentrations of river water. in the present investigation, natural flocculation processes concept is used to reduce the elemental contents of industrial wastewater. for this purpose, various amounts of saline water were added to an artificial industrial wastewater with known concentrations of heavy metals. the results of ...

The effect of xanthan gum (XG) addition on physicochemical properties of 2wt% whey protein isolate (WPI) stabilized oil-in-water (O/W) emulsions containing 20% v/v menhaden oil was investigated by measuring droplet size, viscosity, microstructure, creaming profile and oxidative stability. In fresh emulsions, addition of XG at different concentrations did not show any significant effect on the s...

A radiological study o f the small intestine o f 17 untreated patients in the acute phase ofschistosomiasis was performed. Twelve patients (70% o f total) had alterations: nine had clear-cut thickening o f the duodenal and jejunal folds, one flocculation, one fragmentation and one thickening o f mucosae, flocculation and fragmentation o f the barium column. There was no correlation o f the gast...
