Journal ArticleDOI
Activated sludge model No.2D, ASM2D
Mogens Henze,Willi Gujer,T. Mino,Tomonori Matsuo,M. C. Wentzel,G.v.R. Marais,Mark C.M. van Loosdrecht +6 more
TL;DR: ASM2d is based on ASM2 and is expanded to include the denitrifying activity of the phosphorus accumulating organisms (PAOs), which allows for improved modeling of the processes, especially with respect to the dynamics of nitrate and phosphate.
Journal ArticleDOI
A general model for single-sludge wastewater treatment systems
Journal ArticleDOI
Calcium carbonate crystallization kinetics
TL;DR: In this article, the kinetics of calcite carbonate were studied by following changes in pH only on batch solutions of CaCl 2, NaHCO 3 and NaOH in the presence of calcitic seed crystals.
Journal ArticleDOI
The activated sludge process—3 single sludge denitrification
TL;DR: The general aerobic bi-substrate active-site death-regeneration activated sludge model including nitrification is extended to include the kinetic behaviour of the denitrification process in single sludge systems, which simulates very closely the response of the multi-reactor nitrification-denitification process configurations under both constant and cyclic flow and load conditions.
Journal ArticleDOI
Saturator performance in dissolved-air (pressure) flotation
John Bratby,G.v.R. Marais +1 more
TL;DR: In this paper, a volumetrically measured air precipitated at atmospheric pressure was used for determining the mass of air dissolved under pressure by volumetric measuring air precipitation.
