First described by Alfred C. Redfield in 1934, the concept of a balanced C:N:P ratio is fundamental to ecological stoichiometry, indicating the optimal elemental proportions for biological systems, particularly marine phytoplankton.

The solids retention time (SRT) is a critical operational parameter in biological wastewater treatment, directly influencing microbial health and effluent quality. This guide will explain precisely *how to calculate digester srt* and interpret the results to optimize your system’s performance.
