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.

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.

Electrochemical and microbiological characterization of paper mill biofilms

Biofouling, 2010
Biofilm samples collected from inside and outside the press and former sections of paper machines in a Northwestern Ontario paper mill for a period of 2 years were characterized microbiologically and electrochemically. Bacterial community profiling was done using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and selected ...

Experimental investigation into electrochemical milling of Ti6Al4V

Journal of Manufacturing Processes, 2017
Abstract Electrochemical milling (EC milling) avoids complex electrode design which is often a burden in sinking ECM. In this process material is removed by a simple geometric tool following a predefined path in a layer-by-layer fashion. High strength temperature resistance (HSTR) material like Ti6Al4V is extensively used in different field starting ...

Electrochemical properties of LiFePO4 prepared via ball-milling

Journal of Power Sources, 2009
Abstract LiFePO4 cathode materials with distinct particle sizes were prepared by a planetary ball-milling method. The effects of particle size on the morphology, thermal stability and electrochemical performance of LiFePO4 cathode materials were investigated.

Dependence of Milling Time on Electrochemical Properties of Nano Si Electrodes Prepared by Ball-Milling

Journal of Nanoscience and Nanotechnology, 2011
Morphology, crystallinity and electrochemical properties of Si powders fabricated by a mechanical milling process with milling time of 6-40 h were investigated by means of FESEM, XRD, Raman, TEM and cell test. Average size of Si powders was reduced to sub-micrometer scale after 10 h-milling and 40 nm-Si powders could be obtained at 48 h-milling.

Experimental Investigations on C-263 Alloy by Electrochemical Milling

The International Journal of Advanced Manufacturing Technology, 2019
Electrochemical machining has great potential of machining of any HSTR metals due to its various advantages like free of tool wear, thermal, and residual stresses. The process of electrochemical milling is similar to conventional electrochemical machining (ECM).

Factors influencing the kinetics of electrochemical reactions in milling

Journal of Materials Science, 2004
Input of mechanical energy at a high rate can drive a system and induce phase transformations and chemical reactions away from equilibrium. The evolution of such a change depends on both thermodynamic as well as kinetic factors. Besides the microstructural changes like attainment of nanostructure, which alters the overall free energy, the high rate of ...

Electrochemical behaviour of high-energy ball-milled TiFe alloy

Journal of Alloys and Compounds, 2002
Abstract The effect of high-energy ball-milling (HEBM) on the electrochemical properties of TiFe electrode material has been investigated. The discharge capacity of HEBM TiFe material increased from 0 to 64 mA h g −1 (at 4 mA g −1 discharge current).

Combined milling of electrical discharge ablation machining and electrochemical machining

The International Journal of Advanced Manufacturing Technology, 2021
This paper proposes a combined milling process of electrical discharge ablation machining (EDAM) and electrochemical machining (ECM) as an alternative to the low efficiency problem of less efficient electrical discharge machining (EDM) and to reduce the recast layer of EDAM.
