Description:

Wang, LK and Wang, MHS (2022). Dissolved oxygen model, vapor pressure,  evaporation lagoon, and flotation  post aeration; In:  “Evolutionary Progress in Science, Technology, Engineering, Arts and Mathematics (STEAM)”, Wang, LK and Tsao, HP (eds.), 4 (7H), STEAM-VOL4-NUM7H-JULY2022. 55 pages. July 2022, Lenox Institute Press, Massachusetts, USA.    https://doi.org/10.17613/63ms-gg85   ..........ABSTRACT: This publication introduces: (a) mathematical models of evaporation, vapor pressure, and dissolved oxygen in fresh and saline waters under any temperatures or pressures; (b) evaporation lagoon application and analysis; (c)  stream water quality control, reaeration and dissolved oxygen analysis; and (d) five post  aeration  technologies: diffused post aeration,  mechanical post aeration, cascade post aeration, u-tube post aeration,  and flotation post  aeration.  The authors highly recommend the adoption of high-rate dissolved air flotation (with only 3 to 5 minute detention time) for final clarification in a wastewater treatment plant (WWTP) because the residual DO in DAF/WWTP effluent is higher than 5 mg/L at all time, thus the flotation post aeration is already included without extra effort.    This publication and a poem, The Wind Blows Red Leaves to the Cloud (風吹紅葉至雲端), are dedicated in memory of  an  authors' lifetime dear friend.
