What is a bladder tank?
A bladder tank is a type of pressure vessel commonly used in water supply systems to store and regulate water pressure. It consists of a flexible bladder or diaphragm that separates the water from the air inside the tank. The bladder is typically made of a durable material such as rubber or polyurethane, and it expands and contracts depending on the water pressure.
The bladder tank is connected to the water supply system, usually near the pump, and it helps maintain consistent water pressure throughout the system. When the water pressure drops below a certain level, the bladder tank releases compressed air into the system, increasing the pressure. On the other hand, when the pressure exceeds a certain level, the bladder tank stores the excess water until it is needed.
This type of tank offers several advantages over traditional pressure vessels. Firstly, it helps to reduce pump cycling. By storing water and maintaining a constant pressure, the pump doesn’t have to turn on and off as frequently. This not only prolongs the life of the pump but also saves energy. Additionally, a bladder tank helps to eliminate water hammer, which is the loud banging noise that can occur when water flow is suddenly stopped or started.
Bladder tanks are available in various sizes and capacities to suit different water supply systems. Small residential systems may only require a small bladder tank, while larger commercial or industrial systems may need larger tanks to meet the demand.
Installing a bladder tank in a water supply system is relatively straightforward. It is important to properly size the bladder tank by considering factors such as the peak water demand, available space, and regulatory requirements. Once the tank is installed, it should be properly maintained and inspected periodically to ensure its optimal performance.
In conclusion, a bladder tank is a valuable component of a water supply system that helps store and regulate water pressure. It offers several benefits such as reducing pump cycling and eliminating water hammer. Whether in residential, commercial, or industrial applications, bladder tanks play a crucial role in maintaining efficient and consistent water pressure.
