Design and Construction of an Installation for Testing Bubble Generators Used for Water Aeration
The paper presents an installation comprising four fine bubble generators each with a circular perforated plate with ∅ 0.2 mm orifices. There is a water tank inside the installation in which compressed air is introduced. 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 (H).
