What role does the Captive Air Tank (bladder tank) serve in a water treatment system?

A Captive Air Tank, also known as a bladder tank, plays a crucial role in maintaining a minimum pressure within a water treatment system. The tank is designed with a flexible bladder that separates air and water. When water is pumped into the tank, the bladder expands, compressing the air. This compression creates a pressure cushion, ensuring that there is a steady flow and consistent pressure of water throughout the system.

This functionality is important for many applications, as it helps prevent the pump from cycling on and off too frequently, thus extending the lifespan of the equipment and maintaining adequate pressure for system operations. The tank effectively acts as a buffer, accommodating fluctuations in demand and ensuring that there is always enough pressure to deliver water when needed.

In contrast, the other options do not accurately reflect the primary function of the captive air tank. While temperature regulation, water storage, and chemical filtration are important aspects of water treatment systems, they are not the direct roles of the bladder tank. The tank’s primary feature is its ability to stabilize and maintain pressure, which is essential for efficient system performance.
