Fertilizers from composting of olive-mill wastewaters

International Biodeterioration & Biodegradation, 1996
The aerobic bioremediation of olive-mill wastewaters produces a high quality compost, characterized by a considerable presence of nutrients, mainly organically-bound nitrogen (1.5-3%), a good level of humification (degree of humification=78%; humification index=0.28), and by the absence of phytotoxicity.

Xanthan production from olive-mill wastewaters

International Biodeterioration & Biodegradation, 1996
Olive mill wastewaters (OMW) are a by-product from olive oil manufacture that cause environmental pollution. These wastes have been used as substrate for the production of the extracellular polysaccharide xanthan by Xanthomonas campestris NRRL 31459-S4L41.

Electrochemical treatment of olive mill wastewater

Journal of Chemical Technology & Biotechnology, 2007
AbstractBackground Olive mill wastewater (OMW) constitutes a very strong agro‐industrial wastewater posing severe environmental threats in olive oil producing countries. The main objective of this study was to treat olive mill wastewater by electrochemical oxidation.

Catalytic Oxidation of Olive Mill Wastewater

International Conference on Civil, Biological and Environmental Engineering (CBEE-2014) May 27-28, 2014 Istanbul (Turkey), 2014
Catalyst based on Cu supported on 13X zeolite has been prepared and tested for catalytic wet peroxide oxidation of olive oil mill wastewater. The influence of catalyst postsynthesis treatment as well as operating temperature in oxidation process has been studied.

Ozonation of weathered olive mill wastewaters

Journal of Chemical Technology & Biotechnology, 2006
AbstractThe treatment of fully and partly weathered olive mill wastewaters by means of ozonation was investigated, with emphasis on the effect of treatment conditions (organic loading, treatment time, ozone concentration) on the extent of chemical oxygen demand (COD) and total phenol degradation, colour removal as well as ecotoxicity to the marine ...

Solar distillation of olive mill wastewater

Renewable Energy, 2004
A solar still was employed for the dewatering of olive mill wastewater over a series of consecutive days. The collected distillate and the remaining pulp were analyzed to test the method for treating agro-food industry wastewater. The efficiency of solar distillation of olive mill wastewaters was examined.

Anaerobic digestion challenge of raw olive mill wastewater

Bioresource Technology, 2011
Olive mill wastewater (OMW) was digested in its original composition (100% v/v) in an anaerobic hybrid. High concentrations (54-55 kg COD m(-3)), acid pH (5.0) and lack of alkalinity and nitrogen are some OMW adverse characteristics. Loads of 8 kg COD m(-3) d(-1) provided 3.7-3.8 m3 biogas m(-3) d(-1) (63-64% CH4) and 81-82% COD removal.

Electrochemical mineralization of anaerobically digested olive mill wastewater

Water Research, 2012
A novel approach was developed for the energetic valorisation and treatment of olive mill wastewater (OMW), combining anaerobic digestion and electrochemical oxidation. The electrochemical treatment was proposed as the final step to mineralize the remaining OMW fraction from the anaerobic reactor.

Rhizosphere dynamics during phytoremediation of olive mill wastewater

Bioresource Technology, 2011
The potential of phytoremediation as a treatment option for olive mill wastewater (OMW) was tested on five perennial tree species. Cupressus sempervirens and Quercus ilex proved tolerant to six-month OMW treatment followed by six-month water irrigation, whereas Salix sp. and Laurus nobilis and, later, Pinus mugo suffered from phytotoxic effects.
