Exploration of the Linkage between the A:a gradient and oxygen transfer efficiency as a measure of response to treatment with inhaled nitric oxide in a heterogenous group of newborns treated for acute hypoxic respiratory failure
… intrapulmonary and extra pulmonary shunting and oxygen transfer efficiency in the newborn treated for AHRF using inhaled nitric oxide. The aims of this study were to identify linkages between shunting and oxygenation prior to and during inhaled nitric oxide (iNO) therapy and to determine whether …

Diffuser Fouling Mitigation, Wastewater Characteristics And Treatment Technology impact on Aeration Efficiency
… treatment process is dependent on aeration efficiency which supplies the oxygen needed in the treatment process. The process is a complex heterogeneous mixture of microorganisms, bacteria, particles, colloids, natural organic matter, polymers and cations with varying densities, shapes and …

Dynamic modelling of flexible link aerator with embedded holes to generate dissolved oxygen in tiger prawn pond
… are used to increase the level of dissolved oxygen in water by mixing the water in order to ensure that the oxygen content is uniformly distributed throughout the pond. This aerator uses a new concept by using flexible link by implementing embedded holes in its design in. The purpose of …

Flexible link aerator for dissolved oxygen generation in tiger prawn pond
In the aquaculture industry, the dissolved oxygen is one of the important parameters that need to be monitored seriously. Aerator is normally used to increase the level of dissolved oxygen in water. It functions to circulate or mixes the water top to bottom to ensure that the oxygen content is …

Investigation of the Effects of Sequential Anaerobic, Anoxic and Aerobic Zones on Dissolved Oxygen Transfer Parameters in a biological Nutrient Removal Pilot Plant
… and pilot scale determinations of the volumetric oxygen transfer coefficient, K<sub>L</sub>a, were performed on an improved A²/O biological nutrient removal (BNR) pilot plant. Effluent from a full scale primary clarifier, used as pilot plant influent, was found to have an alpha (ratio of process …

The dual digestion of sewage sludge using air and pure oxygen
… The practicability of the system using pure oxygen is well proven. Disadvantages are the high cost of the pure oxygen and the absence of a detailed evaluation of anaerobic digester performance. This report discusses the results of a full-scale investigation into the dual digestion system …

Microbubble fermentation of recombinant Pichia pastoris for human serum albumin production
… human serum albumin (HSA) production is a high oxygen demand process. The oxygen demand is usually met by increased agitation rate and use of oxygen-enriched air. Microbubble fermentation however can supply adequate oxygen to the microorganisms at relatively low agitation rates because of …
