Abstract

Dissolved oxygen content is a paramount indicator of water quality, directly linked to water remediation processes. Aeration processes enhance dissolved oxygen levels in water treatment through hydraulic structures that increase interfacial area between water and air. This study investigates the aeration efficiencies of pressurized flow systems equipped with Venturi devices of two different orifice diameters (12.7 mm and 19.05 mm) connected to four distinct manifold pipe systems. Experiments were conducted at four flow rates (0.60, 0.75, 0.85, and 1.0 m3/h) corresponding to Reynolds numbers ranging from 16,850 to 27,663. The findings demonstrate that orifice diameters and manifold configurations significantly influence aeration efficiency. Venturi type 2 (19.05 mm) exhibited superior air suction performance at higher flow rates, while optimal performance was observed at main flow velocities between 1.5-2.0 m/s. Empirical correlations were developed linking air-to-water flow ratios (Qair/Qwater) with jet lengths, yielding R2 values ranging from 0.87 to 0.99, indicating strong predictive capabilities for system design optimization.
