The installation is designed so as to ensure the monitoring of the following parameters: 1 - The size of the air bubbles; 2 - The appearance of bubble coalescence; 3 - Increasing the dissolved oxygen concentration in water; 4 - The amount of pressure loss that occurs when air passes through the bubble generator; 5 - The efficiency of the aeration process; 6 - Efficacity of the aeration process; 7 - Air consumption; 8 - Electricity consumption; 9 - Air temperature; 10 - Water temperature; 11 - Compressed air pressure; 12 - Hydrostatic load

In this regard, the paper presents the results of theoretical and experimental research on the performance of fine bubble generators built through special technologies. The orifice plate of fine bubble generators were performed by microdrilling. Through micro-drilling, three types of perforated plates with orifices of Ø 0.1 mm, Ø 0.3 mm, Ø 0.5 mm, were performed. The results of the experimental researches on the increased dissolved oxygen concentrations in water function of time for the three constructive versions are presented.</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":"Researches Regarding Water Oxygenation with Fine Air Bubbles","attachmentId":114031809,"attachmentType":"pdf","work_url":"https://www.academia.edu/118394834/Researches_Regarding_Water_Oxygenation_with_Fine_Air_Bubbles","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/118394834/Researches_Regarding_Water_Oxygenation_with_Fine_Air_Bubbles"><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="4" data-entity-id="67642920" 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/67642920/Evaluation_of_the_Effect_of_Operating_Parameters_on_the_Performance_of_Orifice_Porous_Pipe_Type_Micro_bubble_Generator">Evaluation of the Effect of Operating Parameters on the Performance of Orifice/Porous Pipe Type Micro-bubble Generator</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="41861860" href="https://ugm.academia.edu/AswatiMindaryani">Aswati Mindaryani</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Engineering and Technological Sciences, 2020</p><p class="ds-related-work--abstract ds2-5-body-sm">The micro-bubble generator (MBG) is a novel aeration technology utilizing the concept of fluid flow through an orifice, where air is sucked into the internal chamber of the MBG by the pressure difference created by the orifice and immediately pushed by the high-velocity flow of the fluid. This mechanism creates micro-size bubbles with a high dissolution rate. This study focused on studying the effect on the oxygen dissolution rate of the two most important operating parameters, i.e. the volumetric flow rate of the liquid (Q L ) and the volumetric flow rate of the air (Q G ). Various combinations of values for Q L and Q G were systematically compared by means of the oxygen mass transfer coefficient (k L a). The experiment was carried out in a transparent container of 2.8 m x 0.6 m x 0.4 m filled with tap water that was aerated using an orifice/porous-pipe type MBG. The dissolved oxygen (DO) values were measured at distances of 60 cm, 120 cm, and 180 cm from the MBG outlet.

transitions in a horizontal tube of 700 mm. The tube is assembled with a bubble generator. The present study varies the flow-rates of water and air. The data collection mainly uses a high speed camera to capture the bubbles at different distances along the horizontal tube. Image processing uses MATLAB for evaluating the bubble size. The data interpretation uses Yw dimensionless parameter in representing the level of the bubbles vertical rise in the horizontal tube. The bubble generator produces bubbles in the range of 0.8-3.1 mm at the inlet of horizontal tube using water flow-rates (Qw) of 120-170 litre per min (LPM) and air flow-rates (Qa) of 2-10 LPM. The diameter of the bubble increases as it moves horizontally from the inlet to the outlet of the horizontal tube and this finding is statistically significant. The bubble vertical rise is visually obvious and has been quantified along the horizontal tube. The YW increases axially ...</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":"Air Bubble Size and its Transitions in a Horizontal Tube Produced by Venturi-Nozzle Bubble Generator","attachmentId":112852349,"attachmentType":"pdf","work_url":"https://www.academia.edu/116831075/Air_Bubble_Size_and_its_Transitions_in_a_Horizontal_Tube_Produced_by_Venturi_Nozzle_Bubble_Generator","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/116831075/Air_Bubble_Size_and_its_Transitions_in_a_Horizontal_Tube_Produced_by_Venturi_Nozzle_Bubble_Generator"><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":65616322,"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":65616322,"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_65616322" 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.
