Wastewater modification processes in a stabilization reservoir: anew mathematical model

Risultato della ricerca: Other

Abstract

The paper presents a mathematical model for the simulation of the ecology of awastewater stabilization reservoir (WSR). WSRs are hypertrophic aquatic systems devotedto water storage in warm countries where shortage conditions are often encountered.Several factors that affect the stabilization reservoir’s effluent quality were taken intoaccount: hydraulics and hydrology, solar radiation, reaeration, algae, zooplankton, organicmatter, pathogens, and sediment-water interactions. The model quantifies the specificinfluence of each factor on effluent quality, and evaluating the correlation between thedifferent factors. State variables included in the model were: algae, dissolved oxygen,organic matter, zooplankton and indicator bacteria. The model was applied to an Italianstabilization reservoir located in the south part of Sardinia: Simbirizzi lake. The modelgenerated satisfactory results and can be employed as a useful tool for environmental waterquality management of stabilization reservoirs.
