Abstract:

A method to estimate heat losses from a rapid wastewater infiltration basin under winter operation is developed. The analysis is theoretical and considers two modes of operation, one with a permanent ice cover on the basin and one without. The loading of the infiltration basin is intermittent. The analysis provides a complete heat budget. The equations are expressed in a form which permits estimation of frequency of loading of a basin as a function of loading depth. Heat losses to the atmosphere, formation of an ice cover and cyclic freezing, and thawing of the soil are included in the analysis.
