Gravity Filters Manufacturers

Gravity Filters consist of an open-topped box, drained at the bottom and partly filled with a filtering medium, usually clean sand. Gravity filters are usually employed for municipal applications and on some industrial applications. Gravity filters are open to the atmosphere at the top and the water percolates through the filter bed by gravity. Gravity filters are free surface filters that are much more commonly used for municipal applications. Gravity filters are usually made of concrete and are operated similarly to sand filters.
