Surface aeration is a process used to increase the oxygen levels in water bodies, such as ponds and lakes. This technique involves agitating the water's surface, allowing air to mix with the water. It is commonly used in wastewater treatment and aquaculture to promote healthy aquatic environments. The primary goal of surface aeration is to enhance the biological processes that depend on oxygen, such as the breakdown of organic matter by bacteria. By improving oxygen availability, surface aeration helps maintain water quality and supports the growth of aquatic life, including fish and plants.
