What happens when a filter is operated to a head loss that exceeds the head of water over the media?

Dissolved air will be released causing air binding
It enhances the filtration efficiency
The filter becomes more effective
The water quality improves

The correct answer is: Dissolved air will be released causing air binding

When a filter operates to a head loss that exceeds the head of water over the media, dissolved air can be released, which may cause air binding. This occurs because the pressure in the filter drops significantly, leading to a situation where the water cannot flow through the media as designed. The creation of air pockets, or air binding, can hinder the filtration process, as air within the system reduces the effective area through which water can flow, thereby impacting filter performance and creating inefficiencies. In a properly functioning filtration system, there is a delicate balance between head loss and the pressure driving the flow through the media. When head loss becomes too great, it can disrupt this balance, leading to issues like reduced flow rates and compromised filtration. The release of dissolved air not only affects filtration efficiency but also can lead to uneven flow patterns and other operational challenges within the system. Thus, understanding the relationship between head loss and water pressure is crucial for maintaining optimal filter operation and ensuring effective treatment of water.
