How to control Odour and Algae with Aeration?
In layered ponds, the stinking layer of water remains trapped at the bottom, becoming increasingly saturated with hydrogen sulphide. The surface water cools, its density increases, and it begins to sink to the pond's bottom as the hot summer gives way to cooler fall conditions. Turnover is a mixing cycle that drives the water at the pond's bottom to rise. When the surface and lower waters mix, the previously held hydrogen sulphide is released, resulting in a massive outpouring of a foul gas.
This combination can result in fish fatalities, algae blooms. Algae is vital, but if it isn't kept in check, it can cause a slew of issues in a pond's ecosystem. There are a number of techniques to manage and prevent serious algal problems in a pond, but aeration is frequently used to treat a wide range of issues. Even if aeration isn't considered a direct treatment for algae, it can have a substantial impact on the algae and related pond health.
What is Aeration?
Aeration is the process of forcing the water in a pond to circulate by injecting compressed air into it at key spots. Continuous circulation inhibits stratification and hydrogen sulphide accumulation. A properly designed aeration system will also drive oxygen-rich surface water to circulate throughout the pond on a regular basis, resulting in an even oxygen distribution throughout the water column. This oxygen-rich environment encourages the growth of aerobic bacteria, allowing them to break down organic materials on a continuous basis without running out of oxygen. As long as circulation is maintained, oxygen will be available, anaerobic bacteria will be kept at bay, and no rotten egg odour will be present.
Aeration in Wastewater
It may appear like odours are inescapable in wastewater treatment lagoons, but they are actually a sign that something is wrong with the treatment process. The simplest technique to fix a system is to use aerators to add more dissolved oxygen, which will feed beneficial microorganisms. Aerators also mix the lagoon at the same time, reducing sludge at the bottom, where odour-causing anaerobic bacteria thrive. It's also crucial to have adequate aeration power to respond to seasonal changes. Bacteria become more active in warm weather, necessitating more oxygen to maintain the growing aerobic bacterial population.
Aeration in Water Bodies
During an algae bloom and die-off, aeration can help safeguard your pond and your fish. Adding an aeration device to the water will add oxygen and aid to buffer the effects of an algae die-off, which can occur naturally or as a result of other treatments. Aeration will also cause agitation on the surface of the pond or body of water. This is advantageous in a number of ways.
To begin with, it aids in the elimination of still stagnant water areas by simulating natural breeze. Algae blooms are most common during the summer, when the weather is hot, calm, and sunny. The movement at the surface, which removes stagnant areas, reduces the amount of space available for algae to develop. Even basic water movement will help to reduce the amount of algae in the pond. Algae dislike flowing water and surface agitation, preferring instead to grow in motionless, stagnant places.
Aeration should not be regarded as a panacea or silver bullet, but rather as one of several techniques used in conjunction with other algae-control methods. Adding aeration is never a terrible idea, and most of the time it will improve water quality, not to mention that increased oxygen levels are beneficial to your fish, any odour issues, and the overall health of your pond environment.
