The formulas to calculate the dimensions of a floating-type square digester are:

1. Inner Side (\(S_d\)):

\[ S_d = \left( \frac{1.15 \cdot V_d}{r} \right)^{\frac{1}{3}} \]

2. Digester Height (\(H_d\)):

\[ H_d = r \cdot S_d \]

Where:

• \(S_d\) is the inner side in meters (m).
• \(V_d\) is the effective digester volume in cubic meters (m³).
• \(r\) is the height to side ratio.
• \(H_d\) is the digester height in meters (m).
