Abstract

The highly loaded olive mill wastes are characterized by low pH value, high electrical conductivity, and high content of sugar, phenols, and organic acids. In this work are shown the results pollutants removal from olive mill wastewater by adsorption and biosorption process on activated carbon and Aspergillus niger fungal pellets, as well as treatment of olive mill waste by composting process. The obtained results show that activated carbon removed 35 % organic matter and 47 % phenols, while fungal pellets removed 42 % organic matter, 57 % phenols, and 39 % colour. The obtained conversion during composting process of olive mill waste and tobacco was 45 %.
