Wastewater Treatment on Soils of Low Permeability.
Abstract
The study was limited to land treatment as a means of achieving advanced wastewater purification. Land treatment has the advantage of incorporating the recycling concept directly into its treatment mode, resulting in replacement rather than depletion of natural resources. Also, some form of control over ecologically damaging components is retained. This report presents results of a literature review on various methods of treating wastewater on land and also presents results of model tests of the overland flow method, with particular emphasis on nitrification and denitrification. Two types of soil systems for overland flow treatment of wastewater were investigated during these model tests. One soil was from an 8-year-old commercial cannery wastewater treatment site. The other was from an untreated natural site in a national forest that was low in indigenous soil organic matter; consequently, this latter system was amended with sludge in order to increase its organic matter content. Thus, both experimental soils represented soil systems that had more organic matter and biological activity than an average heavy clay soil.
