Calculation and interpretation of effluent discharge objectives of dairy industry: Case Edough's dairy - Annaba (Algeria)

Aquatic environment owns vary from depend on using and hydrodynamic conditions vulnerabilities. The contribution of water effluent can profoundly affect the physico-chemical composition of the receiving environment. These changes are strongly related to the hydrological regime of rivers. In order to limit the burden and concentrations of contaminants in the receiving environment, several methods have been developed. Regarding to this study, it focuses on agro food waste (dairy) in a natural receiving environment (Seybouse wadi, Algeria NE). In earlier study (2011-2012), physico-chemical and organic analyses have been used by using the calculation method (EOD) to undermine the protection of the receiving environment. Based on release of environmental objectives calculation of each quality criteria and water use showed major overtaking conventional chemical contaminants studied causing an immediate threat to health and or the environment.
