How long water remains in contact with filtration media is an important metric—especially in wastewater applications. Empty bed contact time (EBCT) gives you a clearer understanding of how quickly water moves through the filtration system and whether the filter is able to do its job when water is moving at a specific velocity. Our EBCT calculator measures contact time in cubic feet or cubic meters, to give you a clearer understanding of the efficacy of filtration media for specific applications. You can calculate EBCT time using either media volume or tank capacity information.
