Abstract
Our work concerns the physico-chemical and bacteriological characterization of the sludge from
the sludge from the Ouargla wastewater treatment plant in terms of pH, EC, dryness fertilizing
elements (N, P, K, Mg), volatile matter in suspension totale and faecal coliforms and fecal
streptococci.
The results obtained show that this sludge characterized by a very high dryness which was
estimated at 95% approximately average suspended volatile matter, alkalinity and salinity, the
presence of nitrogen, phosphorus, potassium and magnesium as fertilizing elements,
contamination by total coliforms and the absence of faecal coliforms and faecal streptococci.
