The transfer of gases across the air-water interface has received much attention over the past two decades, particularly in light of increased societal interest in the exchange of greenhouse gases and pollutants between natural water bodies and the atmosphere. Gas transfer at the interface between liquids and gases holds great fascination for a.
Especially with increasing population and industrialization, gas transfer at water surfaces has become a critical factor in the understanding of the various pathways of wastes in the environment and of their engineering management. This interfacial mass transfer is, by its very nature, highly complex.
The transfer across the surface of environmental waters is of interest as an important phase in the geophysical and natural biochemical cycles of numer ous substances; indeed it governs the transition, one way or the other, be tween the dissolved state in the water and the gaseous state in the.
The Seventh International Symposium on Gas Transfer at Water Surfaces was held Mayin Seattle, Washington, USA. The Symposium has occurred every five years since to bring together the scientific and engineering community investigating.
Esa Kari Vakkilainen, in Steam Generation from Biomass, Sootblowing. Heat transfer surface fouling is significant when we burn biomass with a high ash content. Due to deposits, the boiler thermal efficiency is reduced and corrosion of the heat surfaces occurs faster.
A model of air–water gas transfer that combines the surface renewal and surface divergence models is formulated and found to agree with the data from both open-channel flows and wind-driven.

Water treatment plants require gas transfer to dissolve chlorine gas or ozone. Gas transfer can also be used to remove unwanted volatile chemicals such as carbon tetrachloride, tetrachloroethylene, trichloroethylene, chloroform, bromdichloromethane, and bromoform from water (Zander et al., ).
Abstract. Measurement of Oxygen Transfer in Clean Water was developed to calculate the rate of oxygen transfer from diffused gas and mechanical oxygenation devices to water. The Standard is applicable to laboratory-scale oxygenation devices with small volumes of water as well as to full-scale systems with water volumes typical of those found in the activated sludge wastewater treatment process.
Gas Transfer Introduction Exchange of gases between aqueous and gaseous phases is an essential element of many environmental processes.
Wastewater treatment plants require enhanced transfer of oxygen into activated sludge tanks to maintain aerobic degradation. Water treatment plants require gas transfer to dissolve chlorine gas or ozone. Gas File Size: 98KB.

Such an analogy is well proven for solid-gas and solid-liquid interfaces, but such a justification is not available for a gas-liquid interface. Byers and King9 studied mass transfer from a gas-liquid interface under isothermal conditions.
