Types of Sand Filters
Sand filters come in different types, each designed to cater to specific water purification needs. Here are the most common types:
- Gravity Sand Filters: These filters rely on gravity to move water through a bed of sand. They are suitable for residential and small commercial applications.
- Pressure Sand Filters: These filters use pressure to force water through the sand bed. They are ideal for larger residential and commercial applications.
- Backwashing Sand Filters: These filters use a backwashing process to clean the sand bed. This process helps to remove accumulated debris and extend the filter’s lifespan.
- Cartridge Sand Filters: These filters use a cartridge filled with sand to purify water. They are suitable for small-scale applications and are easy to install.
