Theoretical study of the influence of mixing in the SNCR ...

2000-11-1  A theoretical study of the influence of mixing on the selective non-catalytic reduction (SNCR) process has been performed. The study includes the use of a detailed kinetic reaction mechanism together with a simple approach for mixing based on the “maximum mixedness model” proposed by Zwietering (1959).

Influence of mixing on the SNCR process - ScienceDirect

1997-8-1  An experimental and theoretical investigation of mixing in the SNCR process was performed. The experiments were carried out in a bench scale reactor using the flue gas from a natural gas burner as the main gas and injection of a jet of NH 3 mixed with carrier gas in crossflow. The results show a dependency on the carrier gas flow at temperatures above the optimum temperature for NO reduction.

The influence of mixing process on wastewater treatment

2015-6-30  Mixing process makes it easier to trap harmful substances by increasing a contact area between a flocculant and an undesirable substance. Mechanical agitators within a few minutes perfectly mix sewage with the flocculant so that it is able to combine with a greater number of dirt particles. The complex increases its weight and settles down at the bottom, which leads to clarifying water surface much faster. The mixing process can also affect the morphology of an activated sludge by shear stress interference or ensuring it more favorable aerobic conditions . Shear stresses disintegrate the sludge granules and increase their active surface, which may adsorb a greater amount of dissolved solids. The mixing process may also be accomplished by the process of aeration, because the compressed air causes the circulation of the waste water. In addition, this process provides more available oxygen for life processes of organisms, which degrade the organic compounds contained in the wastewater. Air nozzles may also be used. Compressed gas is introduced to the lower part of the chamber, its center or to its perimeter. This results in the effective mixing of the sludge without fragmentation of fibers. Specific volume of the gas supply to the lower zone of the chamber moves upwards in approximately the same volume of waste water . It provide better contact of the substance with the greatest sludge microbial biomass (which use adsorbed colloidal particles and other solutes as food source) but above all, its goal is to oxidize the activated sludge to provide it with favorable conditions for metabolic activity .
