The term 'aeration' signifies the process of including air to water. Given that air includes about 22-percent oxygen, aeration is meant to add even more oxygen to the water. There were numerous methods of attaining this in the past. Most of those aeration methods included spraying surface water therefore the name surface splashers. Pumps or propellers that were powered by electric motors that were either post-mounted or float mounted, caused fountains of water splashing into the air. These systems can be a great choice for shallow water just like for a fish hatchery. They are ineffective for deep water bodies due to the fact that they only spray surface water. As you will find out below, oxygen is more required at the bottom of the lake. Moreover, these units require electric wires to be placed in the water. These electric wires can easily result in heavy power losses and shock threats, thus it would certainly be better if aeration can easily eliminate making use of electrical power in the water. Additionally, these surface are also water skiing and boating hazards. Pond Bottom aeration is different in that the aerators include oxygen not just to the surface of the water however also to the water at the bottom of the lake; in fact, they aerate all the water in the lake. This is an essential element. Effectively aerating the bottom of the lake enhances the living conditions at that depth therefore bring in insect larvae, snails and other aquatic organisms on which fish feed. All standard systems that work by pumping water to the air require great deals of electric power. It is interesting to note that it takes less energy to pump air as it weighs a lot less than water. For instance, it is 600 % cheaper to make use of an air pump to aerate water than to utilize an equivalent horsepower ranked water pump given that they use 6 times less electricity. Nevertheless, windmills are an exception. Their only issue is that they are extremely ineffective during the winter months when the water freezes. When the suface aerators expels air to the surface of the water, the air bubbles that rise deliver along the water at the bottom to the top and present it to the atmosphere. These volumes of water exchange bad gases to much more oxygen while at the surface. Bacteria attack oil, whey, manure, milk, and community waste from sewage plants, mills, waste from factories, mills, and other pollutant that makes its way into the water. These bacteria will certainly utilize oxygen whenever it is readily available. This kind of 'feast' allows them to grow fast and increase into multitudes and they end depleting all the dissolved oxygen that exists in the water. Due to the high biological oxygen demand of the bacteria, and there being none left in the water, the fish generally pass away. For fish to make it through, the bacteria will need to act upon the toxins totally. With aeration, the pollutants are speedily oxidized or burned up. It is interesting to keep in mind that with adequate aeration, it is effortless for fish to make it through also in highly polluted environments such as a feed lot runoff pond or a lagoon in a tertiary sewage treatment plant.
