Abstract

Abstract :

The rationalization of the use of conventional water resources has become an imperative management. In this, and in the context of sustainable development, agricultural reuse of treated wastewater and sludge generated by the treatment appears to be an alternative for the preservation of water resources and the environment and the promotion of agriculture sector.

It is around this axis as revolves this work, based primarily on the aptitude of treated wastewater and sewage sludge of WWTP of Medea to the reuse in agriculture. To do this, analyzes of these by-products were made at the laboratory level.

The results, projected and compared to the recommendations of FAO and WHO standards, revealed that: The treated waters of the WWTP of Medea, despite their high salinity, are reusable for irrigation of certain salt-tolerant species. The high concentration of faecal coliforms, fact that these waters can not be used without chlorination. The Sewage sludge, by the relatively low amount of organic matter it contains is considered a fertilizer, more than organic amendment. In addition, the C/N presents an important availability and rapid nitrogen mineralization.
