Rapid Gravity Filters

Rapid Gravity Filters

An RGF Tank is normally constructed in multiple chambers and includes filtering and backwash modes of filtration requiring drainage at both high and low levels. The RGF normally follows the Flocculation process in the treatment of raw water.

FLI Carlow have developed a precast concrete panel, subfloor drainage and launder channel system to standardise the construction of the RGF and to provide a cost effective solution.
