Sentence examples for mass of ozone from inspiring English sources

Within the European Union, ambient-air quality standards for ozone are expressed as mass of ozone per volume of air.

We calculated iFs for primary PM as well as secondary PM associated with various particle precursors (SO2, NOx, VOCs) and ozone (defined as the mass of ozone inhaled per unit mass of NOx or VOC emissions).

The mass velocity of ozone was measured by standard iodometry; also the values of COD were determined with a standard potassium dichromate oxidation method (Rand et al. 1976).

Countercurrent bubble column reactors are most commonly used in water disinfection for effecting mass transfer of ozone to the aqueous phase.

The designed bubble column reactor was investigated for increasing the rate of mass transfer of ozone, the rate of oxidation of phenol in the solution, the solubility and decomposition rate of ozone in the distilled water were also studied at different flow rates.

We then examine the associations between day-to-day variations in air masses, levels of ozone, and hospital admissions for asthma and MI over the same 9-year time frame.

The effect of bubble diameter and plume structure on mass transfer efficiency of ozone in bubble plumes is investigated numerically.

A computational model for a reactor used in advanced water treatment was proposed to represent, simulate and predict the mass transfer process of ozone in water (gas liquid).

In this paper we study the mass transfer process of ozone dissolution in a bubble plume inside a rectangular water tank, as a model problem for a water purification system.

On the basis of assumptions for the mass transfer and reactions of ozone, three approaches were considered: equilibrium, kinetic, and lump models.

In the case of ozone, the mass conservation expression can be simplified, because the emission term is not there and the deposition terms can be ignored.
