Anaerobic Digestion Fundamentals

facilities (WRRFs). The primary objective of anaerobic digestion is to convert the microbiological cells and other solids generated during the treatment process to a stable end product. Other solids stabilization processes include aerobic digestion, composting, thermal drying, thermal oxidation, and alkaline stabilization.

Liquid Stream Fundamentals: Aeration Design

submerged diffusers to distribute gaseous air bubbles in the process liquid (see Figures 5 and 6). Fine pore diffusers create smaller bubbles which maximize the air-water interface, and subsequently allow for greater oxygen transfer from the air to the liquid. Once in liquid form, the oxygen is available for use by the
