Abstract

Sewage treatment in the Cordoba province of Argentina, a large tourist area, is presently non-existant. The sewage flows into the Lago San Roque lake, resulting in algae blooms and unsafe drinking water for surrounding water systems. A pilot plant for sewage treatment consisting of impermeable basins filled with soil in which marsh plants are grown has been constructed; %modelled according to a German design. The wastewater is mechanically presettled, then passed into the fixed bed where limnophytic plants such as reeds (Phragmites spp.) or bulrush (Scirpus spp.) in conjunction with soil microorganisms, convert and treat the organic matter, thereby purifying the water. The system capacity is measured in Population Equivalences (PE's), and a single treatment plant can process from 5 to 40,000 PE's.
