Introduction to the types of air tanks
There are different types of air water tanks that can be classified according to different features such as shape and material. Based on the shape, these tanks are usually divided into three categories: spherical, cubic, and cylindrical or vertical, and based on the material they are made of, they are often divided into four groups: metal, polyethylene (plastic), concrete, and wood.
Metal Air Tank
Steel or galvanized metal tanks are one of the oldest types of air tanks that have relatively high strength and longevity. These tanks are often produced in two types, open and closed. Open types are used as firefighting water tanks or for agricultural and industrial purposes, and closed types are used to supply drinking water. Of course, as it was said, the decay of these types of tanks will cause changes in the appearance of water, and this is one of the negative points of using metal tanks, and it has caused most of the polyethylene tanks to be used as a substitute for these metal tanks. become.
Concrete Air Water Tank
Another type of air tanks are made of concrete. The distinctive feature of concrete tanks is their very high strength. As their name suggests, these types of tanks are made of concrete and have a very high resistance to deformation due to physical factors and are also resistant to chemicals. This category of air tanks are often made in two types, cylindrical and frame-shaped, and are mostly used in the water supply of industries and large factories, and are usually not useful in urban uses.
Air Water Tank Performance
As mentioned, air water tanks are designed and built in different types and sizes. However, they all function similarly. Aerial water reservoirs are, in fact, a type of water storage source that is placed at a height. These tanks are widely used to compensate for the drop in water pressure in tall buildings.
The reason for air water tanks being located at a high altitude is the possibility of supplying water pressure. The higher the altitude, the higher the water pressure. So that the water pressure increases by 0.43 psl per foot of height. For this reason, some air water tanks are installed at a height of 50 meters above the ground. Since air tanks are installed. They should be able to provide the water pressure needed by all the surrounding buildings, they are placed at a high altitude.
If there is a hill nearby, the water tank can be placed on it. The operation of the aerial water tank should be such that when the water is cut off, it can supply the required water for at least one day. On the other hand, the design of air water reservoirs is to supply the average water pressure; In this way, water consumption is significantly saved.
