“BACKGROUND: Olive oil production is an important economical activity in the Aegean region of Turkey. However, the effluents of the olive oil producing mills with their high organic loads and toxic compounds are causing serious environmental problems. The anaerobic biological treatment of olive mill wastewater (OMWW) using the treatment plants of the regional industries could be a method of choice and within the scope of this study floccular and granular sludges were investigated in batch mode for their success in the treatment of OMWW while producing biogas.
The major CA4P molecular weight limitation of this treatment is the inhibition of methanogenic bacteria by the phenolic compounds in OMWW. Thus an integrated solution was suggested in which a pre-treatment step (dephenolization) was also introduced before biological step.
RESULTS: The effluents of 27 olive mills out of 47 were
found to have total phenolics (TP) less than 3 g L(-1) and could be treated anaerobically after simple dilution. The biogas production for the untreated OMWW was higher for floccular sludge than for the granular sludge (68.5 ml and 45.7 ml respectively). Combined pre-treatment experiments, first coagulation with polyaluminum chloride, followed by flocculation with cationic polyelectrolyte and finally Fenton’s oxidation, selleck screening library could remove 80% of TP and 95% of the total suspended solids.
CONCLUSION: OMWW having TP values less than 3g L(-1) can be treated anaerobically using floccular sludge after simple dilution and biogas can be produced. For OMWW samples having higher TP values pre-treatment is necessary
and the pre-treatment given in this study may be used effectively. (C) 2010 Society of Chemical Industry”
“Objectives: We wanted to compare autonomy recovery after open and endovascular infrainguinal surgery for critical limb ischaemia (CLI) in octogenarians.
Materials and methods: We performed a retrospective analysis of 167 consecutive CLI octogenarians who underwent infrainguinal open surgery click here (OS) or endovascular surgery (ES) between 2003 and 2008. OS and ES groups were compared in terms of autonomy level (Parker score), survival, limb salvage and patency rates.
Results: Preoperative autonomy level was similar in both groups (OS n = 109, ES n = 58) but 6-month postoperative autonomy level was better after ES (p = 0.01). There was a trend towards better survival after OS (74% at 1 year, 62% at 2 years, 32% at 4 years with OS and 68%, 50%, 17% respectively for ES p = 0.06), but no difference regarding limb salvage (91% at 1 year, 90% at 2 years, 89% at 4 years for OS and 94%, 87%, 86% respectively for ES, p = 0.939) and primary patency (76% at 1 year, 59% at 2 years, 50% at 4 years for OS and 82%, 75%, 32% respectively for ES, p = 0.467).
