Olive oil mill waste is characterized by its high organic matter content, especially fatty acids, polyphenols, sugars, and proteins. These nutrients can be used as a source of energy for biogas production. However, olive oil mill waste can also contain heavy metals such as lead, cadmium, copper, and zinc that can be absorbed by plants. In addition, very high concentrations of heavy metals can also...
Hospital effluents are one of the main sources of contamination of groundwater and rivers if they are collected by urban networks and sent to wastewater treatment plants (WWTP), without prior treatment. These effluents are potential vectors of resistant pathogenic bacteria and could contribute to the spread of these strains in the environment. The Sebou River is used as a receptacle for domestic water...
It is necessary to understand the process of anaerobic digestion (AD) of sewage sludge and to find an adequate strategy to improve the efficiency of methane production. In this work, the production of methane and detailed properties of sludge are determined. The physico-chemical parameters of the digester 1 'D1' and the digester 2 'D2' remain in the optimal range of AD stability with a median value...
