Interactive Biochar Hydraulics Calculator

The physical performance of your filter is governed by key hydraulic metrics. Use this calculator to explore how changing your filter's dimensions and flow rate impacts its performance. Aim for an **Empty Bed Contact Time (EBCT)** of at least 30 minutes for effective removal of chemical contaminants.
