During the backwash cycle, what happens to the zeolite?

• A. It expands in size
• B. It gets smaller due to attrition
• C. It becomes inactive
• D. It forms new bonds

Answer: (B)

During the backwash cycle, zeolite experiences attrition, which results in it getting smaller. The backwash process involves reversing the flow of water through the zeolite media in a filtration system to remove impurities that have accumulated. As water flows backward, the zeolite particles can rub against each other and against the surfaces of the filtration chamber. This mechanical action can cause some zeolite particles to break down, leading to a reduction in size. Therefore, the correct understanding is that attrition during the backwash cycle causes the zeolite media to become smaller, which is a key aspect of maintaining the filtration system's effectiveness.
