Description
Unpolluted water maintains in solution the maximum quantity of dissolved oxygen, which is in equilibrium with the partial pressure of oxygen in the atmosphere, When dissolved oxygen is removed from solution, an unbalance is created and the deficiency is made up by oxygen passing into solution through the water surface exposed to the atmosphere, water is influenced by physical factors such as winds and waves, and
chemical factors, such as surface active agents and oil films. This phase of the project deals with the effect of surface active agents on the reaeration process.
