A study of fine coal dewatering by high temperature and pressure filtration
… coal by the application of high temperature and pressure to a filter slurry. This method might have the possibility of replacing conventional thermal dryers for fine coal drying. In addition, the effect of temperature, pressure, dry cycle time, slurry density, cake thickness, and evaporation on …

Pressure filtration of destabilized colloidal systems in an unstirred batch cell: Experimental investigation
A simple model for the filtration of a destabilized colloidal suspension was proposed by Cohen (3). It was shown mathematically that the cake permeability was a function of flocculation rate $\omega$. Thus by controlling the flocculation rate it is possible to alter the structure of the cake formed …

Effects of Bloom-Forming Algae on Fouling of Integrated Membrane Systems in Seawater Desalination
… applied to algal cells was detrimental to low-pressure filtration because of the release of highly-fouling organic matter. The highly fouling fraction was material large enough to be retained on a 0.22-microm microfilter but small enough that it was not removed by centrifugation or coarse …

Developing a Novel Ultrafine Coal Dewatering Process
… hexane-coal slurries by combining liquid-solid filtration and in-situ vaporization and removing the solvent by a carrier gas (i.e., drying) are reported. The filtration behaviors are studied under different solid mass loading and filtration pressure. It is shown that using pressure filtration …

Biphasic Nanoparticle Inks for Direct Write Assembly of Three-Dimensional Periodic Structures
… composition exhibit a greater resistance to pressure filtration (or jamming) during direct ink writing. Using these novel inks, 3-D periodic structures are patterned with features approaching 10 mum, which correspond to nearly an order of magnitude reduction in size compared to those produced …

The effect of certain sludge floc properties on the dewatering characteristics of biological and chemical waste sludges
… dewatering studies using laboratory-scale vacuum filtration, sanbed, and filter press equipment. The experimental results showed clearly that particle size distribution was a key parameter for describing the response of sludges to each of the dewatering methods utilized. For biological sludges, …

Effect of Digestion Processes on Dewatering and Bound Water Content of Sludge
… combines the above-mentioned processes, by pressure filtration of sludge followed by application of vacuum and heat. However, when cationic polymer conditioned sludge is dewatered in the J-Vap, the polymer is suspected to interact with the filter media at high temperatures, resulting in the …

Scale-up of Using Novel Dewatering Aids
… the final cake moistures as a function of vacuum pressure, filtration time and specific cake weight. The model can be useful for the scale-up of vacuum disc filters (VDF) and horizontal belt filters (HBF). Simulation results indicate that dewatering aids can be very effective, especially when used …

Fine Coal Dewatering Using Hyperbaric Centrifugation
… This novel method combines centrifugation and pressure filtration within a single process to substantially reduce moistures over what can be achieved using conventional dewatering systems. In the current study, steady-state and dynamic dewatering models were developed in order to be able to …

Keramische Membranen auf Basis LPS-SiC: Schlickerentwicklung und Beschichtungsverfahren
Die Filtration unter aggressiven Einsatzbedingungen, z.B. Einsatz in korrosiven Medien, Abgasfiltration, stellt besondere Anforderungen an das Filtermaterial. Sogenanntes "Liquid Phase Sintered Silicon Carbide" (LPS-SiC) erfüllt die Anforderungen sehr gut. Deshalb bestand das Ziel der …
