Bioremediation of olive mill waste water and its use as a bio fertilizer

Abstract

Olive oil mill wastewater (OMW) constitutes a major environmental problem especially for mediterranean countries, where most of the world's olive oil production. Treatment of the OMW is highly demanded due to the hazards of its high chemical oxygen demand (COD), total phenolic content (TP), turbidity and color. In the present study, penicillium chrysogen um was selected as the predominant grown fungus in the presence of phenolic compounds (13 g/l). Bio stimulation was tried to assist, TP removal, decolorization, turbidity and COD reduction before disposal to the environment. Separate addition of glucose and urea resulted in 62% removal of the phenol, while the addition of KH{sub 2}PO{sub 4} resulted in 70% removal with lower effect on both turbidity and coloration. Consecutive use of the filtration prior or post to the bio stimulation revealed that the use 4 kGy enhanced phenolic degradation while the use of filtration post bio stimulation was the most effective treatment for phenolic removal (70%). Turbidity was also decreased from 9.81 to 2.72, and the decolorisation was increased from 28.5% (in control samples) to 77.6% and COD was decreased by only 21%. Analysis of the treated OMW revealed the presence of trace amounts of phenolic compounds, sugars and  More>>

Analysis of the treated OMW revealed the presence of trace amounts of phenolic compounds, sugars and some minerals, suggesting its potential use as a bio fertilizer. Ocimum basilicum cultivated with the treated OMW showed the highest germination percentage (60%) in comparison with that irrigated with tap water and untreated OMW (50%, 20%) respectively. (Author)}
