Wellbore Skin in Mine Dewatering and Drinking Water Supply: Field Observation, Mineralogy and Hydraulic Effect

When it comes to well loss and efficiency, the occurrence of wellbore skin layers is one of the strongest influencing factors. Besides difficulties to remove the skin layer that is necessary during the drilling process, it is also not easily possible to determine if a skin layer is present in a well and whether or not it imposes a certain degree of well loss. With this work, three types of skin...

Innovative Algae Dewatering Technology

Abstract This paper describes a novel technology for dewatering of bio materials, such as algae, for biofuel production and other applications. This hydrodynamic separation (HDS) technology uses customized fluid flow patterns to focus suspended particulates into a well-defined band near a side wall of a curved channel, and where they can be separated off with a suitably designed flow splitter. ...

Metode lociranja za bodoče lokacijske storitve

Povzetek. V tem prispevku podajamo pregled obstoječih in prihajajočih metod lociranja v mobilnem okolju. Z rastjo mobilnih tehnologij in povečano uporabo ter razširitvijo mobilnih terminalov, mobilne storitve in aplikacije, med njimi tudi tako imenovane lokacijske storitve, pridobivajo čedalje več pozornosti. Kontekst uporabe je pomemben element za personalizacijo bodočih sistemov za pridobivan...

Sludge Dewatering by Impulse Drying

An innovative and energy efficient sludge dewatering technology has been developed. The technology, impulse drying, involves briefly contacting the sludge under pressure with a heated surface. A unique feature of impulse drying is that the majority of moisture removal occurs as lipid water. A pilotand laboratory-scale demonstration was performed on low ash primary paper mill sludge. The pilot-s...
