Enzymatically hydrolyzed and agitated biomass suspensions: experimental determination of fiber size distributions and filtration characteristics
(Editura Academiei Romane, 2014)
Separation processes in general present a significant challenge in the production of bioethanol from lignocellulosic materials. Solid-liquid separation,prior to the concentration of ethanol (for instance, by distillation),is ...
Influence of enzyme loading on enzymatic hydrolysis of cardboard waste and size distribution of the resulting fiber residue
(Elsevier, 2014-05)
Enzymatic hydrolysis of lignocellulosic biomass to sugars alters the properties of the cellulosic fibers. Several process variables, including enzyme loading, play an important role in these changes. Many physical properties ...
Treatment of mining wastewater polluted with cyanide by coagulation processes: a mechanistic study
(Elsevier, 2019-11-25)
In this work, coagulation and electrocoagulation for the removal of cyanide ions contained in synthetic mining wastewater were evaluated paying particular attention to the elucidation of the coagulation mechanisms. Iron ...
Prediction of pressure filtration characteristics of CaCO3 suspensions ground in a vertical stirred media mill
(Elsevier, 2015-11)
Cake filtration is an important unit operation in the processing of minerals and pigments. The filtration characteristics are strongly dependent on the upstream processing of the ore, such as grinding parameters. This study ...
Purification efficiency of natural freeze crystallization for urban wastewaters
(Elsevier, 2019-11-21)
Human population growth and urbanization are aggravating water quality problems in many regions, and wastewater volumes and quantities of pollutants are increasing due to greater industrial and urban activity. Thus, it is ...
Real-time monitoring of the moisture content of filter cakes in vacuum filters by a novel soft sensor
(Elsevier, 2019-09-15)
The moisture content of filter cakes is probably the most important characteristic that should be kept at a desired level in industrial cake filtration applications to maintain consistent product quality and minimize energy ...
Specific energy consumption of vacuum filtration: Experimental evaluation using a pilot-scale horizontal belt filter
(Taylor and Francis Inc., 2019-03-07)
Horizontal vacuum belt filters are used for continuous solid–liquid separation in a wide variety of industrial processes. Despite the low pressure difference (usually Δp < 0.8 bar), the high air pumping requirement to ...
Pressure filtration properties of sludge generated in the electrochemical treatment of mining waters
(Elsevier, 2020-05-18)
In this study, batch electrocoagulation (EC) experiments were performed with synthetic mining water in various conditions in a laboratory-scale 1L reactor. The process was scaled up and the selected results were verified ...
Assessment of the Pore Diameter Measured in Gas-Liquid Displacement Porometry: Effect of the Capillary Constant
(Begell House, 2022-11-16)
Determining pore sizes of porous media accurately is essential for many reasons. The standard ASTM F316 describing calculations used in gas-liquid displacement (GLD) porometry includes a factor B or a capillary constant. ...
Dissolution kinetics of aluminosilicates from biomass ashes in alkaline solutions
(Elsevier, 2021-01-06)
This research explores the influence of fly ash source, alkali concentration and temperature on the dissolution kinetics of Al and Si. The characteristics of the reaction products and the solid residue were evaluated with ...
