Description

Given the incoming average flow, the number of settling tanks and the geometric characteristics of each one, checks whether it fits the Brazilian standards for domestic sewage treatment plants.

$$ \begin{align*} 20 \leq Q/A \text{ (m³/m² . day) } \leq 24 \end{align*} $$

$$ \begin{align*} 3.0 \leq Y_L \text{ (m) } \leq 3.5 \end{align*} $$
