EBCT

Empty Bed Contact Time

A critical operational parameter in water treatment systems that measures the duration water is in contact with treatment media such as activated carbon filtration materials or ion exchange resins. EBCT calculates residence time determines treatment effectiveness optimizes media utilization quantifies contact duration and establishes design parameters enabling proper sizing and operation of water treatment systems to achieve target contaminant removal bacterial reduction disinfection levels and water quality objectives through sufficient contact with treatment media.
