Filtration rate

Description

Given the flow to be filtered, the superficial area of each filter, and the number of filters, the average filtration rate is calculated.

Formula

86400⋅Qn⋅A\frac{86400 \cdot Q}{n \cdot A}

Where:

  • Q/AQ/A = filtration rate (m³/m².d)\text{(m³/m².d)}
  • QQ = flow (m³/s)\text{(m³/s)}
  • AA = superficial area of each filter (m²)\text{(m²)}
  • nn = number of filters
