Finite-Dimensional Methods for Optimal Control of Autothermal Thermophilic Aerobic Digestion [PDF]
, 2012 An activated sludge process (ASP) is a biochemical process employed for treating sewage and industrial waste-water, which uses microorganisms and air (or oxygen) to biologically oxidize organic pollutants, producing a waste sludge (or floc) containing the oxidized material.

Increased salinity improves the thermotolerance of mesophilic nitrification [PDF]
, 2014 Nitrification is a well-studied and established process to treat ammonia in wastewater. Although thermophilic nitrification could avoid cooling costs for the treatment of warm wastewaters, applications above 40 A degrees C remain a significant challenge.

Dual-Control of Autothermal Thermophilic Aerobic Digestion Using Aeration and Solid Retention Time [PDF]
Water, 2017 Autothermal thermophilic aerobic digestion (ATAD) is an advanced sewage sludge treatment which allows compliance with increasingly demanding regulations. Concerning sludge pasteurization, a certain average temperature must be assured in the digester during batch treatment.

A consistent dimensional analysis of gas–liquid mass transfer in an aerated stirred tank containing purely viscous fluids with shear-thinning properties [PDF]
, 2012 This paper deals with gas–liquid mass transfer in an aerated stirred tank containing Newtonian or shearthinning fluids. The aim is to demonstrate that, for a given mixing system, an unique dimensionless correlation gathering all the mass transfer rates (
