Otterbine Genesis Lake Aerating Fountains

Since its conception in 1952, Otterbine have developed a reputation within the industry for designing and manufacturing high quality, long lasting and efficient lake aeration systems.

Constructed from corrosion resistant 316 marine grade stainless steel, all Otterbine aeration units are built to last and are therefore covered under a 5 year comprehensive warranty. Maintaining high levels of oxygen in lakes is absolutely crucial to ensuring a healthy and sustainable ecosystem, and with the highest oxygen transfer rates in the industry as independently tested by the University of Minnesota, the Otterbine aeration units are one of the best options available. With a power output ranging from 1HP up to 5HP, and both 240v (single phase) and 380v (three phase) options, there are Otterbine units suitable for almost any large pond or lake.

Often lakes can fall victim to run-off from the surrounding areas which can massively affect the water chemistry, for example, agricultural run-off that contains fertilisers loaded with phosphorous and nutrients. Unfortunately, the same nutrients that encourage crop growth also encourage the growth of algae once they end up in the lakes ecosystem and as a result it is important to manage the level of nutrients to prevent the algae from taking over. This is where oxygen levels come into play. Aerobic bacteria digest nutrients, turning them into only water, carbon dioxide, and polysaccharides. However, they do require oxygen to complete this process.

Low levels of oxygen in the water leaves only the anaerobic bacteria to digest the nutrients. This process releases harmful methane, hydrogen sulphide and ammonia into the lake, causing a foul odour and a poor environment for wildlife. Anaerobic bacteria are also incredibly inefficient at digesting nutrients, taking up to 6 times longer than aerobic bacteria. This is why aeration is so important in maintaining a healthy lake.

The Genesis aerating fountains provide good oxygen transfer while producing a beautiful two tiered pattern, complete with a total of 16 streams that create a dramatic and eye catching effect.
