Treatment of olive mill wastewater using a coagulation
Treatment of olive mill wastewater using a coagulation–flocculation process either as a single step or as post‐treatment after aerobic biological treatment. Katerina Pelendridou. School of Science and Technology, Hellenic Open University, GR‐26335 Patras, Greece.
In olive-oil-producing countries, large amounts of waste material are generated as by-product for which there is no ready use and in some cases may have a negative value because of the cost of disposal. Most of these countries depend on fossil fuels for their energy uses, and olive mill wastes can be used to supplement such energy sources using thermochemical conversion processes such as
Treatment of Olive Mill Wastewater with Constructed Wetlands
Olive Mill Wastewater (OMW) represents a significant environmental threat in all olive producing countries, mainly in the Mediterranean basin such as Italy, Greece, Tunisia and Spain, which cover
Highlights Membrane distillation is applied for olive mill wastewater treatment. PTFE membranes of different pore sizes used under different operating conditions. Pure water production and concentration of natural polyphenols from OMW. Concentration factors higher than 1.78 after 8 h of operating time were obtained. High temperatures did not affect phenolic content and its antioxidant activity.
Treatment of olive mill wastewater using High Power
Olive oil processing is a fledgling industry in Florida; however, treatment of olive mill wastewater (OMW) is a significant barrier to commercialization. This study assessed combining high-power-ultrasound (HPU) and electro-Fenton (EF) process in reducing contaminants in OMW; thereby allowing byproduct utilization without adversely affecting
31-Jan-2012 2 European Olive Oil Production 42% 20% 18% 20% Greek situation The olives and olive oil are inextricable part of Greek culture In Greece there are 150.000.000 olive trees cultivated in 765.000 hectare The yearly production of each tree rises up to 300 kg of olives The 1/3 of Greek farmers are working on cultivation of olives

Abstract The aim of this work was to examine the performance of Pseudomonas putida mt-2 in treating olive mill wastewater (OMW) effluent after dilution with sterilized water (33%, v/v) to reduce it...
Photochemical UV/TiO2 treatment of olive mill wastewater (OMW)
dUniversite´ Paul Sabatier, 118 route de Narbonne, 31062 Toulouse, France Abstract Olive mill wastewater (OMW) was treated by photocatalysis using TiO 2 under UV irradiation on the laboratory scale. The chemical oxygen demand, the coloration at 330 nm, and the level of phenols all showed decreases which, after a 24-h treatment, reached 22%, 57%
Olive mill wastewater (OMWW) is a by-product of the olive oil extraction industry. Its dumping creates severe environmental problems in the Mediterranean countries. The phytoxicity of OMWW is due to the phenolic substances and is evaluated through a genotoxicity method. An aerobic treatment of OMWW was conducted during 45 days.
Treatment of olive mill washing water by ultrafiltration
Olive oil production requires important quantities of washing water containing low oil concentrations, but classical processes used to recover or to eliminate this oil are ineffective. This study presents a membrane technique to treat olive oil mill washing water using different commercial ultrafiltration membranes: one organic (PCI) and two ceramic (Ceraver) membranes. The influence of the
Treatment of wastewater and olive paste from oil mills The olive oil sector is an enormous economic, cultural and environmental asset in some countries, such as Spain, Italy or Greece. As a result, improving the treatment of the waste obtained after olive oil production and attempting to revalue it is crucial for improving the competitiveness
- Does powdered activated carbon control pharmaceutical compounds in municipal wastewater treatment?
- Powdered activated carbon (PAC) dosing to a conventional (AS) reactor is a low-investment option for controlling pharmaceutical compounds (PhCs) in municipal wastewater treatment, but its advantages and limitations in real operating environments are not fully assessed.
- Can powdered activated carbon remove micropollutants by adsorption?
- The present research work is based on an electrochemical technique in combination with powdered activated carbon (PAC) for the removal of micropollutants by adsorption as an advanced stage purification step from effluents of pilot plant wastewater treatment plants (WWTP). The effluents of sedimentation tank comprised of wastewater plus PAC (WWPAC).
- Can super-fine powdered activated carbon remove micropollutants from wastewater treatment plant effluent?
- Desalin Water Treat 57 (20):9203–9215 Bonvin F, Jost L, Randin L, Bonvin E, Kohn T (2016) Super-fine powdered activated carbon (SPAC) for efficient removal of micropollutants from wastewater treatment plant effluent.
- Can powdered activated carbon be used in a sludge treatment plant?
- Powdered activated carbon in an activated sludge treatment plant Responding to changing conditions: how powdered activated carbon systems can provide the operational flexibility necessary to treat contaminated groundwater and industrial wastes
