Air Binding:
The clogging of a filter due to resistance offered by the medium particle along with the impurities exceeds the static head of water.
Due to the above resistance negative head or vacuum pressure is developed at the bottom layer of the filter medium.
The negative head created in the bottom releases dissolve gases that rises to the surface and leads to binding of the voids of the filter medium from the bottom.
The above process of operational trouble caused in rapid sand filter is called as Air Binding.
To avoid Air Binding:
Proper cleaning of filter should be done when
- head loss becomes 2.5 to 3.5 m or
- Negative head becomes 1.2 m.
