Abstract: By incorporating special environments for methane fermentation and photosynthetic oxygenation, advanced integrated ponding systems attain high degrees of primary and secondary treatment and significant degrees of tertiary and quaternary treatment of sewage and organic industrial wastes. When properly designed in appropriate locations, the systems virtually eliminate sludge disposal, minimize power use, require less land than conventional ponds, and are much more reliable and economical than mechanical systems of equal capacity.
