heal.abstract	Waste from NonCyanide stripper; a toxic liquid associated with the production of olive oil, was treated by an electrochemical method using Ti/Pt as anode and stainless steel 304 as cathode. In this technique, sodium chloride (40 g/L) was added to the wastewater as an electrolyte and the mixture was passed through an electrolytic cell. Due to the strong oxidizing potential of the chemicals produced (chlorine, oxygen, hydroxyl radicals, and other oxidants), the organic pollutants were wet oxidized to carbon dioxide and water. After 1 h and 10 h of electrolysis at 0.26 A/cm(2), total chemical oxygen demand (COD) was reduced by 41% and 93%, respectively, total organic carbon (TOC) was reduced by 20% and 80.4%, volatile suspended solids (VSS) were reduced by 1% and 98.7%, and colors were reduced by 70% and 99.4%. The mean anode efficiencies were 1960 g h(-1) A(-1) m(-2) and 340 g h(-1) A(-1) m(-2). Also the mean energy consumption was 1.273 kWh/kg of COD reduced and 12.3 kWh/kg of COD reduced for 1 and 10 h, respectively. These results indicate that this electrolytic method of oxidation of waste from NonCyanide stripper is feasible. (C) 1999 Elsevier Science Ltd.	en
