for Fine Particle Separation","grobid_abstract":"The demand for instruments that are suitable for the separation of fine particles and biological cells is steadily increasing. Various innovative particles have already implemented in bulk products and many others are close to commercial availability. Tubular bowl centrifuges offer high centrifugal forces at reasonable throughputs.

The problem with microplastics is that they do not disappear in the environment, Plastic takes an extremely long time to degrade completely and during this long period, these particles of different sizes risk causing harm to a variety of organisms including humans. This study will decrease the number of microplastics in drinking water and prevent many diseases from spreading through it. The proposed idea is to utilize the centrifugal force technique in a simple machine that looks like a washing machine in the internal structure, it will apply at the bottom of a ship to purify water from microplastics. After the prototype was tested, the results showed the prototype fulfilled the design requirements of Cost reduction and efficiency preservation as the prototype efficiency is 99.75%. The project also proved to be safe for the marine creature and ready to be used. In conclusion, the project is valid and offers the world a huge opportunity to decrease water pollution.

The bio-suspension is prepared by adding baker yeast and albumin bovine serum (BSA) into a buffer solution at pH 7.0; and the BSA molecules are purified from the mixture in a swing-arm centrifuge under rotational speeds ranging from 500 to 4000 rpm. A numerical program is established for estimating the concentration profiles of yeast cells in the filter chamber, the cake growth rate, the cake properties and filtration rate. The variations of the average specific filtration resistance and average porosity of cake are estimated based on a Voigt-in-series compression model. The simulated results of cake properties and filtrate rate agree fairly well with the available experimental data. In addition, the separation efficiency of BSA can be predicted accurately under various conditions once the BSA permeation through the cake and the filter septum is analyzed. To compare the separation efficiency of BSA in the centrifugal and cross-flow microfiltration systems, use of centrifugal filtration with a centrifugal effect just over the critical value is an optimum on the viewpoint of operating time, separation efficiency, and energy-saving.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Mechanism of centrifugal filtration for separation of microbe/protein bio-suspension","attachmentId":70105194,"attachmentType":"pdf","work_url":"https://www.academia.edu/53208464/Mechanism_of_centrifugal_filtration_for_separation_of_microbe_protein_bio_suspension","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/53208464/Mechanism_of_centrifugal_filtration_for_separation_of_microbe_protein_bio_suspension"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="109660809" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/109660809/Centrifugal_nanofiltration_for_small_volume_samples">Centrifugal nanofiltration for small-volume samples</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="17745727" href="https://lisboa.academia.edu/CarlosCompleto">Carlos Completo</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Membrane Science, 2017</p><p class="ds-related-work--abstract ds2-5-body-sm">The concentration of small-volume samples containing substances with molecular weight below 1 kDa is usually done by expensive and tedious techniques, and, for this reason it is important to develop expedite and low cost methods. In this work we designed, manufactured and tested an innovative laboratorial centrifugal nanofiltration (CNF) device that accomplishes those targets. The influence of operational parameters on the CNF device performance was comprehensively evaluated, including the effects of: rotational speed, solute type, solute concentration, height of the filtration chamber and angle between the centrifugal force and the membrane surface. Using the developed device to nanofilter three model solute solutions (potassium sulfate, sucrose and polyethylene glycol) we were able to obtain concentration factors higher than 20, reducing the sample volume from 3.2 mL to less than 100 µL of concentrate. Experimental data suggest that the performance obtained is better for negative angles resulting in the disruption of the concentration polarization layer, whereas should lie between 0.2 mm and 0.6 mm. The CNF device proved to be a consistent technique to attain the nanofiltration of small-volume samples for further processing or analysis.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Centrifugal nanofiltration for small-volume samples","attachmentId":107719081,"attachmentType":"pdf","work_url":"https://www.academia.edu/109660809/Centrifugal_nanofiltration_for_small_volume_samples","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/109660809/Centrifugal_nanofiltration_for_small_volume_samples"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="104166386" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/104166386/Further_Development_of_a_Centrifugal_Solids_Separator_Prototype">Further Development of a Centrifugal Solids Separator Prototype</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="254016113" href="https://independent.academia.edu/REYNOSOPRISCILA">PRISCILA REYNOSO</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2016</p><p class="ds-related-work--abstract ds2-5-body-sm">This thesis was made for SansOx Ltd, part of the Finnish Cleantech cluster of companies, whose innovative ideas in the water treatment area have been awarded the WssTP Water Innovation SME Award for two consecutive years. The purpose of the thesis was to make a deeper theoretical research of the physical aspects related to solids separation in one of SansOx's innovations, a centrifugal solids separation device. Based on this research, it was aimed to make a review of the previous tests of the pilot-scale prototypes of the device as well as to develop a plan that would be the base for testing a prototype in a laboratory-scale. The theory of solids separation in the device is strongly linked to hydraulics and particle settling, so the theoretical research was divided into three main subjects: physics and hydraulics, particle separation, and solid separation methods. Some basic principles of physics, such as vectors and forces, are the base for explaining the hydraulics related to fluid flow through pipes as well as for explaining the basic theory of particle settling. Solids separation methods were studied for a comparison between the commonly used methods in water treatment and SansOx's device. With the information of the theoretical research, a review of the conditions of the previous tests of the prototype could be made, as well as finding a cause for the results obtained in the tests. Lastly, the same calculations were used to develop the sizing and testing plan of a laboratory-scale prototype. The results of the calculations showed that the main challenge in the previous testing of the prototypes was to achieve a discharge that would be high enough for separation. The parameters and calculations related to the solids separation were gathered into one single Excel workbook that would serve as a tool for designing a prototype depending on the characteristics of the solution to be treated. Finally, with this tool, a plan for the laboratory-scale prototype was developed.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Further Development of a Centrifugal Solids Separator Prototype","attachmentId":103964761,"attachmentType":"pdf","work_url":"https://www.academia.edu/104166386/Further_Development_of_a_Centrifugal_Solids_Separator_Prototype","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/104166386/Further_Development_of_a_Centrifugal_Solids_Separator_Prototype"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="19353536" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/19353536/2_dimensional_separation_of_biomimetic_particles_by_stopped_flow_centrifugo_magnetophoresis">2-dimensional separation of biomimetic particles by stopped-flow centrifugo-magnetophoresis</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="39540712" href="https://dcu.academia.edu/JensDucr%C3%A9e">Jens Ducrée</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011</p><p class="ds-related-work--abstract ds2-5-body-sm">This paper presents a centrifugo-magnetophoretic principle for the 2-dimensional separation of particles towards cell separation applications. Multi-force particle separation is achieved through the favorable combination of centrifugal sedimentation and magnetic deflection, while a stopped-flow mode (i.e., no fluid flow, mere sedimentation) is implemented to minimize divergent flow-lines and hydrodynamic instabilities typical in pressure-driven microfluidic platforms. The results demonstrate immuno-capture of biomimetic elements by magnetic particles and subsequent routing of these particle tandems to a designated outlet. During separation, shear stresses and forces that can unfavorably alter biological cells are reduced as compared to more common pressure-driven systems. Hence, the novel, stopped-flow, centrifugo-magnetophoretic separation system enables a possible post-separation analysis of mechanically undisturbed cells.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"2-dimensional separation of biomimetic particles by stopped-flow centrifugo-magnetophoresis","attachmentId":40573809,"attachmentType":"pdf","work_url":"https://www.academia.edu/19353536/2_dimensional_separation_of_biomimetic_particles_by_stopped_flow_centrifugo_magnetophoresis","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/19353536/2_dimensional_separation_of_biomimetic_particles_by_stopped_flow_centrifugo_magnetophoresis"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="27761793" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/27761793/Fluid_dynamic_analysis_of_the_solid_liquid_separation_process_by_centrifugation">Fluid dynamic analysis of the solid-liquid separation process by centrifugation</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="47558748" href="https://poliba.academia.edu/RiccardoAmirante">Riccardo Amirante</a><span>, </span><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="52089173" href="https://independent.academia.edu/CatalanoP">P.

In this paper the kinetic and dynamic analysis of these machines is presented, in order to determine the developed forces (needed for the separation of the input mixture) and the power flow paths through the different parts of the machine. The involved physical quantities are formulated into flexible functions, in order to make this modeling applicable to all types of decanters (wide variety of use and dimensions). This project comprises the base of a threefold optimization: a) the separation quality, b) the mixture's capacity and c) the design of the centrifugal machines. The separation chamber is formed by the shell containing the screw conveyor (to drive the constituents to the appropriate exits), for which the correct operation calls for a relative motion between the shell and the conveyor. This is possible by using a two-stage planetary mechanism. The planetary gearbox is of vital importance for the decanter and it is analyzed to determine a) the ratio of power between the inputs of the gearbox and b) the ratio of power between the chamber shell and the conveyor. Modeling of separation chamber is achieved by dividing the chamber into three compartments: a) the separation compartment (removal of the lighter constituents of the mixture) b) the cylindrical compartment (transfer of the heavier constituent) and c) the truncated-conical compartment (the drainage of the heavier constituent due to the continuous change of cross sectional area of the shell). It is concluded that the basic power in each compartment depends on : i) the quantity of the constituents which enter each compartment, ii) the geometry of the shell in each compartment, iii) the geometry of the screw conveyor in each compartment, iv) the nature of the mixture (coefficient of friction, viscosity), and v) the square of the peripheral velocity of both the conveyor and shell. Finally, for the cylindrical compartment it is notable that the ratio of the developed centrifugal force to the force of propulsion depends exclusively on the coefficient of friction of the solid constituent. Specifically, for low values of the coefficient of friction, this ratio increases linearly whereas for higher values the ratio increases non-linearly. Therefore, the maximum permissible coefficient of friction can be determined.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Decanter centrifugal machines for mixture separation","attachmentId":40733369,"attachmentType":"pdf","work_url":"https://www.academia.edu/19000367/Decanter_centrifugal_machines_for_mixture_separation","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/19000367/Decanter_centrifugal_machines_for_mixture_separation"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":40563612,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":40563612,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_40563612" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
