“…In this work, Ti/Pt, DSA-Cl 2 and DSA-O 2 anodes were selected to be evaluated due to both, i) their relatively moderate cost and reliability at industrial scale and ii) they have been commonly used for wastewater treatment [41][42][43][44]. Each electrode needs some experimental conditions recommended by the manufacturer, for example, for DSA-Cl 2 pH has to be between 9 and 11 and the maximum chloride concentration should be 5000 mg L -1 .…”

ELECTROCHEMICAL TREATMENT OF WASTEWATER FROM ALMOND INDUSTRY USING DSA-TYPE ANODES: DIRECT CONNECTION TO A PV GENERATOR ABSTRACTFood industries such as almond industry generate large volumes of wastewater in their processes and common techniques are not always efficient for treating this kind of effluents. In this work, the feasibility of a treatment for pollutants removal of a real industrial wastewater by electrochemical oxidation s studied at laboratory scale and then scaled-up to pre-industrial scale. The first stage of the work was performed at laboratory scale, using a 63 cm 2 cell, where different anodes (Ti/Pt, and DSA anodes (Ti/RuO 2 and Ti/IrO 2 )) and the optimal experimental conditions (pH, current density, temperature and In the second stage the scaling-up of the process from laboratory to pre-industrial scale was performed, by using a 3300cm 2 cell. The electrochemical reactor was finally powered by a photovoltaic generator directly connected, in order to operate by using a renewable energy and a COD elimination of 80 % was achieved.

“…Produced water (PW) is considered as one of the largest waste streams in the petroleum, oil and gas industry. The drilling and extraction operations aiming to maximize the production of oil may be counterbalanced by the huge production of contaminated water with pollutants, such as heavy metals and organic compounds (Wake, 2005;Santos et al, 2006;Ahmaduna et al, 2009). In addition, PW is a serious environmental problem, whose discharge is directly poured into http://dx.doi.org/10.1016/j.chemosphere.2014.07.067 0045-6535/Ó 2014 Elsevier Ltd. All rights reserved.…”

The lube oil wastewater is produced from Lube Oil Bending Facilities (LOBF) located in Egypt. Currently the lube oil wastewater is treated by oil separator followed by Dissolved Air Flotation (DAF) system. Unfortunately, DAFTreated Lube Oil Wastewater (DTLOWW) contains high concentration of the soluble COD.The first part of this work examined the treatability of DAF-Treated Lube Oil Wastewater (DTLOWW) using bench-scale Fenton process. Effects of H 2 O 2 , Fe 2+ doses at different reaction time and wastewater strength have been studied. Optimum H 2 O 2 dose was 0.8 g/l for normal DTLOWW strength (sCOD<2000 mg/l) and 1.2 g/l for high DTLOWW strength (sCOD>2000 mg/l). Optimum H 2 O 2 /FeSO 4 ratio of 3 was achieved for the normal and high strength DTLOWW at pH 3.5.The Second part of this work studied the performance of Pilot-scale Fenton process. Pilot scale Fenton reactor was installed in the field and conducted under the optimum H 2 O 2 /FeSO 4 ratio that achieved from the bench scale work. The reactor was operating in batch basis at 8 hour cycle period divided in six phases. The results showed that residual sCOD was 788 ± 56 mg/l with sCOD removal of 53.6% which amply met with the local discharge Standards for discharging the industrial wastewater to the municipal sewage network. The Fenton process could be used for treatment of the DTLOWW with daily chemicals cost of 1.25-1.50 $/m 3 .
