What are the results of channeling in a sand filter?

Channeling in a sand filter occurs when water flows preferentially through certain paths, bypassing the media and reducing filtration efficiency. This can lead to uneven distribution of flow, resulting in poor removal of contaminants and decreased overall performance. Additionally, it can cause short-circuiting, where some water exits the filter untreated. Regular maintenance and proper design can help mitigate channeling effects and ensure effective filtration.
