In LDT, a laser light beam passed through the bubbles inside the measurement cell and the scattered light was recorded by detectors. In order to show the effectiveness of LDT, an image analysis technique (IAT) was paralellly applied to measure the size of bubbles. To determine the bubble size by IAT, around 200 images were taken in each test. In addition, the important operating parameters of the mechanical flotation cell affecting the bubble size distribution, including the impeller speed, aeration rate and frother concentration, were investigated. The response parameter in this study was Db(50) which represent the size of bubble at which there is 50% of the distribution. The results of this study showed that the LDT and IAT techniques were in a good agreement when Db(50) was in the range of -800+400 µm and ...</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":"Determination of bubble size distribution in a laboratory mechanical flotation cell by a laser diffraction technique","attachmentId":77412484,"attachmentType":"pdf","work_url":"https://www.academia.edu/66079978/Determination_of_bubble_size_distribution_in_a_laboratory_mechanical_flotation_cell_by_a_laser_diffraction_technique","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/66079978/Determination_of_bubble_size_distribution_in_a_laboratory_mechanical_flotation_cell_by_a_laser_diffraction_technique"><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="1" data-entity-id="109522583" 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/109522583/The_influence_of_some_parameters_on_bubble_average_diameter_in_an_electroflotation_cell_by_laser_diffraction_method">The influence of some parameters on bubble average diameter in an electroflotation cell by laser diffraction method</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="60202270" href="https://independent.academia.edu/AchillesDutra">Achilles J B Dutra</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Environmental Chemical Engineering, 2016</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":"The influence of some parameters on bubble average diameter in an electroflotation cell by laser diffraction method","attachmentId":107622588,"attachmentType":"pdf","work_url":"https://www.academia.edu/109522583/The_influence_of_some_parameters_on_bubble_average_diameter_in_an_electroflotation_cell_by_laser_diffraction_method","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/109522583/The_influence_of_some_parameters_on_bubble_average_diameter_in_an_electroflotation_cell_by_laser_diffraction_method"><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="2" data-entity-id="101910237" 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/101910237/Experimental_Investigation_of_Bubble_Size_in_Flotation_Effect_of_Salt_Coagulant_Temperature_and_Organic_Compound">Experimental Investigation of Bubble Size in Flotation: Effect of Salt, Coagulant, Temperature, and Organic Compound</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="270056841" href="https://independent.academia.edu/FarhadSadeghi16">Farhad Sadeghi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">SPE Production &amp; Operations, 2020</p><p class="ds-related-work--abstract ds2-5-body-sm">SummaryFlotation is an important segment of water treatment. Bubbles are generated and dispersed in water where they capture oil and solids residuals and lift them up to the surface. Bubbles are generated either mechanically by agitation or hydraulically by induced gas ejectors. The bubble size has a crucial role in this kind of separation. In general, the smaller the bubbles, the better separation. Water chemistry has an important role in bubble formation and size. A laboratory scale flotation unit was developed to generate the microbubbles with diameters of 10 to 100 µm. The effects of salinity, coagulant, temperature, and ethanol on bubble size were investigated. The addition of 5000 mg/L of sodium chloride (NaCl) affected mainly bubble size with 50 µm diameter, whereas bubble size reduced and diameter decreased by one-half with the addition of NaCl. The bigger bubbles (100 µm size) were affected only at a salinity of 40 000 mg/L, whereas the smaller bubbles (20 to 30 µm) remaine...</p><div class="ds-related-work--ctas"><button

class="ds-related-work--abstract ds2-5-body-sm">Bubble measurement has been widely discussed in the literature and comparison studies have been widely performed to validate the results obtained for various forms of bubble size inferences. This paper explores three methods used to obtain a bubble size distribution—optical detection, laser diffraction and acoustic inferences—for a bubble cloud. Each of these methods has advantages and disadvantages due to their intrinsic inference methodology or design flaws due to lack of specificity in measurement. It is clearly demonstrated that seeing bubbles and hearing them are substantially and quantitatively different. The main hypothesis being tested is that for a bubble cloud, acoustic methods are able to detect smaller bubbles compared to the other techniques, as acoustic measurements depend on an intrinsic bubble property, whereas photonics and optical methods are unable to “see” a smaller bubble that is behind a larger bubble. Acoustic methods provide a real-time size distribution for ...</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":"Comparison of Bubble Size Distributions Inferred from Acoustic, Optical Visualisation, and Laser Diffraction","attachmentId":108144237,"attachmentType":"pdf","work_url":"https://www.academia.edu/110277523/Comparison_of_Bubble_Size_Distributions_Inferred_from_Acoustic_Optical_Visualisation_and_Laser_Diffraction","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/110277523/Comparison_of_Bubble_Size_Distributions_Inferred_from_Acoustic_Optical_Visualisation_and_Laser_Diffraction"><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="9" data-entity-id="50186430" 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/50186430/Measurement_of_particle_loading_on_bubbles_in_the_flotation_process">Measurement of particle loading on bubbles in the flotation process</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="34766860" href="https://independent.academia.edu/MMoys">Michael H Moys</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Minerals Engineering, 2010</p><p class="ds-related-work--abstract ds2-5-body-sm">Methods for estimation or measurement of particle loading on bubbles in the flotation process are reviewed.
