Bioremediation of Olive Oil Mill Wastewaters by Fungal (Trichoderma viride, strain 8/90) Sequencing batch reactor

Olive oil mill wastewaters (OOMWs) still represent an important environmental problem due to the several difficulties which has to be faced for their disposal.The performance of a lab-scale Sequencing Batch Reactor (SBR) for olive oil mill wastewater (OOMW) treatment was investigated. The reactor, preliminarily filled with suspended solids free OOWM was inoculated with Trichoderma viride (strain 8/90) fungal biomass. Influent and effluent dissolved organic carbon (DOC), total suspended solids (TSS) and polyphenols concentrations were monitored. The obtained results showed that the steady state removal of the organic carbon was about 66%, whereas phenolic compounds were reduced by about 50%. 1
