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

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.
