Exploitation of an agroindustrial wastewater: from OMW to biofuels
Owing to acidity, phenolic compounds, suspended substances, high organic content and phytotoxicity, the wastewater coming from the oil mills (OMW) is considered as one of the most polluting agroindustrial effluents.
Our study aimed at demonstrating that the disposal of OMW could be effectively performed in a phytodepuration plant, by taking advantage from the ability of some arboreal trees, like poplar, to grow in OMW-treated soil. A couple of phytodepuration pilot plants were constructed and monitored for 2 years. We observed that, in OMW, pH increased, COD, BOD and phenols decreased, and, most importantly, the trees did not show significant signs of suffering. Since the OMW was completely evapotranspirated without soil-accumulation of phenols, evidence was given that the plants were able to efficiently dispose of the OMW and generate biomass used for biofuel production.

Im Jahr 1991 wurde erstmals ein Abbauprodukt eines Arzneimittelwirkstoffs in Berliner Oberflächengewässern und im Grundwasser nachgewiesen. Dies war gewissermaßen der „Startschuss“ für Arzneimitteluntersuchungen in Umweltproben durch Umweltbehörden, Universitäten und Forschungseinrichtungen aus dem Bereich der Wasserwirtschaft.

In this study in order to determine and investigate the effect of zinc concentration on bacteria resistance threshold, two samples of industrial wastewater(1 and 2) were collected. The concentrations of zinc in samples were 36 and 17 gL-1. In order to access heterotrophic plate count, wastewater samples were cultured on nutrient agar by pour plate method and to count and isolate the Zn resistant bacteria, samples were cultured by spread plate method on PHG-II agar include of 0.5 mML-1 of Zn in three dilution and two replications.
