For which purpose might pressurized tanks be used in water treatment?

The use of pressurized tanks in water treatment primarily focuses on ensuring an even distribution of treatment media. This is vital in processes such as filtration, where the even flow of water through the media is necessary for optimal performance. When water is pumped into a pressurized tank, it helps maintain a consistent pressure, which allows water to be distributed uniformly across the treatment media. This uniformity is essential for the efficient removal of contaminants and for achieving the desired water quality.

While pressurized tanks can indeed serve other roles in a water treatment system, such as aiding in the delivery of treated water or storing chemicals, the primary advantage they provide concerning the treatment media is their ability to optimize distribution and contact time. This feature enhances the treatment process and contributes to more effective removal of impurities, underscoring the importance of even distribution in achieving high-quality water.
