Unravelling colloid filter cake motions in membrane cleaning procedures

Electrostatic colloid-membrane complexation

– We investigate numerically and on the scaling level the adsorption of a charged colloid on an oppositely charged flexible membrane. We show that the long ranged character of the electrostatic interaction leads to a wrapping reentrance of the complex as the salt concentration is varied. The membrane wrapping depends on the size of the colloid and on the salt concentration and only for intermed...

Chemical Cleaning of Utafiltration Membrane after Treatment of Oily Wastewater

Bioconversion of petroleum hydrocarbons in soil using apple filter cake

The aim of this study was to investigate the feasibility of using apple filter cake, a fruit-processing waste to enhance the bioremediation of petroleum contaminated soil. A rotating barrel system was used to study the bioconversion of the xenobiotic compound by natural occurring microbial population. The soil had been accidentally polluted with a total petroleum hydrocarbon concentration of 41...

Odontogenic bacteremia following tooth cleaning procedures in children.

PURPOSE This study was designed to investigate the prevalence and intensity of odontogenic bacteremia from tooth cleaning procedures in children and adolescents. METHODS One hundred and fifty five children receiving dental treatment under general anesthesia at The Great Ormond Street Hospital for Children and Guy's Hospital were recruited. Each child was randomly allocated to one of three too...

Segmentation of Retinal Blood Vessels Based on Cake Filter.

Segmentation of retinal blood vessels is significant to diagnosis and evaluation of ocular diseases like glaucoma and systemic diseases such as diabetes and hypertension. The retinal blood vessel segmentation for small and low contrast vessels is still a challenging problem. To solve this problem, a new method based on cake filter is proposed. Firstly, a quadrature filter band called cake filte...
