Lake & Pond aeration:
Lakes tend to accumulate a lot of organic debris over time. These organics are a nutrient pool of fertilizers that can cause algae to bloom. Excessive algae blooms in ponds without aeration can lead to fish mortality. Fortunately, naturally occurring bacteria can help reduce these bottom organics through the process of oxidation. Matala Aeration Systems increase oxygen throughout the environment, speeding up the process of oxidizing organic and mineral pollution.
By pumping compressed air to the bottom of a lake, lagoon or pond with the use of a diffuser, the rising air bubbles and the friction caused in the water will bring bottom water to the surface where it is exposed to the atmosphere. This is called an "airlift "and can transfer thousands of gallons of water circulation for very little electrical cost. Large volumes of water rising to the surface release noxious gases to the atmosphere, water picks up oxygen while circulating at the surface and brings this oxygenated water back down to the bottom where the bacteria can thrive and oxidize more quickly.
Natural bacteria are stimulated by aeration and circulation and they will feed on muck, organics and the food that normally feeds algae blooms or aquatic plants growth. Using aeration and bacteria is often a safe and sound form of pollution removal.
