The balance tank is an indispensable component of every overflow pool, including overflow pools made of PP (polypropylene) plastic. Its primary role is to maintain a stable water level, ensure the proper functioning of the overflow, and maintain a constant hydraulic balance of the system.
What is a balance tank?
A balance tank is an additional vessel into which excess water from the overflow channel drains. From there, the water is filtered and returned to the pool. It "absorbs" changes in water volume caused by bathers entering and leaving the pool.
Why is a balance tank necessary?
maintains a constant water level in the pool,
prevents water from spilling outside the system,
ensures the proper functioning of filtration,
enables efficient removal of surface contaminants.
How is a balance tank sized?
The volume of the balance tank depends on the pool surface area, the expected number of bathers, and the system's operating regime. For private pools, it is most commonly sized to accommodate the excess water produced under maximum bather load.
Position and construction
The balance tank is most commonly installed in the plant room or in close proximity to the pool, below the overflow level. In PP pools, the tank can be fabricated from PP material, which ensures chemical resistance and a long service life.
Balance tank and automation
Modern systems use sensors and automated controls to monitor the water level in the balance tank, achieving stable and reliable operation without the need for manual intervention.
Conclusion
The balance tank is the heart of the overflow system. Without a correctly sized and installed balance tank, an overflow pool cannot function properly. In PP overflow pools, a high-quality balance tank guarantees a stable water level, excellent hygiene, and long-term system reliability.
