Introduction
The submersible aerator generates liquid flow, creating negative pressure behind its impeller vanes, which draws in air from above the water's surface. As this aspirated air mixes vigorously with water due to mechanical forces inside the impeller and guide vane, it transforms into tiny bubbles. Furthermore, the resulting mixture of air and water is evenly discharged in multiple directions around the circumference. This combined action of air lift and convective currents enhances aeration and agitation efficiency, significantly increasing the dissolved oxygen content in the water.
Application
Mixing and Equalizing Basins: Equalize wastewater pollution load and quantities, thus preventing odor issues.
Activated Sludge Basins and SBR Reactors: Facilitate the biological degradation of organic substances in wastewater.
Sludge Stabilization: Prevents odor problems and aids in further oxidizing organic substances.
Flotation: Used for flotation of oil and grease in wastewater.
Lagoon Aeration: Enhances natural aeration processes to improve water quality.
Neutralization: Neutralizing alkaline wastewater using CO2 or flue gas.
Special Applications: Aerate uses pure oxygen or ozone. Submersible aerators, positioned at the basin's bottom without anchorage, can be easily lifted for maintenance and inspection using a mobile crane.
Features
The oxygen dissolution rate is high, the proportion of tiny bubbles is large, the oxygenation efficiency is high and the oxygenation area is wide.
There is no dead zone in the pool, and the horizontal aeration flow entrained with bubbles can completely wash every corner of the pool bottom.
The structure is simple and compact. The unit has long service life. The bearings can withstand large loads and adopt oil-immersed shaft seals. It can effectively prevent impurities and water in the water from entering the inside of the bearing. These ensure that the aerator works continuously 24 hours a day and operates trouble-free for a long time.
The project investment is small and there is no need to provide an air source, thus eliminating the cost of a blower. It is easy to install and makes little noise.
