Empty Bed Contact Time Calculator

Use this calculator to empty bed contact time in cubic feet or cubic meters. You can calculate the Empty Bed Contact time by media volume or tank capacity.

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.

This is a plug-and-play calculator that’s free to use. Just input your variables, choose your desired method of measurement and the calculator will do the rest!
