Treatment of Olive Mill Waste

Otpadni tokovi nastali tijekom proizvodnje maslinova ulja karakterizirani su niskom pH, visokom električnom vodljivošću, tamnom bojom, visokim udjelom fenola, šećera i organskih kiselina. U ovom radu prikazani su rezultati uklanjanja onečišćujućih tvari iz otpadne vode procesom adsorpcije i biosorpcije na aktivni ugljik i pelete Aspergillus niger te zbrinjavanje komine maslina procesom kompostiranja. Dobiveni rezultati pokazuju da je aktivni ugljik adsorbirao 35 % organske tvari i 47 % fenola, a peleti 42 % organske tvari, 57 % fenola i 39 % boje. Tijekom procesa kompostiranja komine maslina i duhanskog otpada postignuta je konverzija od 45 %.

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 %. This work is licensed under a Creative Commons Attribution 4.0 International License
