Abstract
Nitrogen transformations associated with land disposal of a municipal sewage effluent at Calumet, Michigan, were investigated. The municipal effluent was applied to alternate ponding sites. The infiltration capacity of the soil permits the system to operate without any effluent. One objective was to investigate the effect of variable loading rates (in terms of gallons/sq ft/day) on the nitrification capacity of the soil in order to determine a loading rate that would limit nitrification but not adversely affect the adsorption-ion exchange of NH3-N and PO4-P. Laboratory batch tests were conducted to determine the NH3-N and PO4-P adsorption-ion exchange capacities of the soil of the Calumet site. (Author)
