What is a water aerator?
The aerator is some of the several devices used to add oxygen to the water. Common types include air diffusion aerates, spray nozzle aerates, cone aerates, cascade aerates and forced aerates. Water aeration is used commercially in water and aquaculture treatment and is also used on the domestic market for the maintenance of the pond. These methods can supply insufficient oxygen to the water system, especially under cloudy conditions, or when too much or too little photosynthetic organisms are present. In such cases, it may be necessary to artificially add oxygen to the water using a water aerator. Artificial aeration is generally necessary in aquaculture operations to provide sufficient amounts of disollized oxygen for fish. Aerations may also be needed in domestic ponds or water gardens to maintain the desired population of plants or fish.
The purpose of a water aerate is to increase the surface area of the watergap into contact with air. This allows more air to react with water. Aeration can be made either by movable water with air or moving air with water. The type of water aerator needed for a particular application depends on the efficiency, the chemical properties of the water and the reason for the aeration.
air diffusion is the main method of aeration and involves air movement of water. In the air diffuser, water passes through the trough, while the compressed air is pushed up from the bottom, moving the air with water. This is a relatively ineffective aeration method.
Most water aerates work with moving water air. Some types, such as the aerates of the spray nozzle, work by spraying water currents through the air. Another type works by creating waterfalls and two examples are conical tanks and cascading aerates. The aerates of the tapered tray flows through the watersand vertical cones and over the edges - this is primarily used to remove iron from water. The cascade aerators consist of a series of steps that flow through the thin current, allowing more water to enter into contact with the air.
and the forced tension aerator combines air movement methods with water and water through air. In this type, the water triggers a number of magazines and drips in small streams as it reaches the end, while the fan at the same time stretches the air up with water. These aerates are useful for removing carbon dioxide and hydrogen sulphide from the water.
