Clarkson, W. W.; And Others – 1978
This module examines the basic properties of soil which have an influence on the success of land treatment of wastes. These relevant properties include soil texture, soil structure, permeability, infiltration, available water capacity, and cation exchange capacity. Biological, chemical and physical mechanisms work to remove and renovate wastes…

Clarkson, W. W.; And Others – 1978
This module describes important criteria to use in evaluating land for waste treatment sites and tells where the necessary information for such evaluation can be obtained. Among the important criteria for evaluation are climate, land use of potential site and surrounding areas, topography, drainage characteristics, soil properties, and geology.…

Clarkson, W. W.; And Others – 1978
The purpose of this module is to develop a general procedure to decide the feasibility of land application as a waste management alternative, given a specific problem situation. This information provides a framework within which to apply the information presented in all other modules in the program. An outline of the general procedure followed in…

Clarkson, W. W.; And Others – 1978
This module introduces the physical, biological, and chemical constituents of wastewaters and sludges which are of concern in land treatment systems. The characteristics of typical municipal wastewater are tabulated for strong, medium, and weak sewages. Some of the factors affecting pollutant concentrations are listed. Flow, distribution and…

Clarkson, W. W.; And Others – 1978
Drainage for land treatment sites must be evaluated with respect to the purpose the system is meant to achieve. Off-site drainage controls the flow of storm runoff onto the site or groundwater incursion into the soil within the site. On-site drainage is employed for a variety of reasons. These two areas of drainage control must be designed as a…

Clarkson, W. W.; And Others – 1978
Land application systems are discussed with reference to the options available for applying wastewater and sludge to the site. Spray systems, surface flow methods, and sludge application schemes are all included with discussions of the advantages and disadvantages of each option within these categories. A distinction is made between the choice of…
