Feasibility of electrochemical oxidation process for treatment of saline wastewater
Background: High concentration of salt makes biological treatment impossible due to bacterial plasmolysis. The present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting pH, salt concentration, reaction time and applied voltage. Methods: The sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...
متن کاملEffective Modified Carbon Nanofibers as Electrodes for Capacitive Deionization Process
Carbon materials have the advantages of good electrical conductivity and excellent chemical stability, so many carbon materials have been introduced as electrodes for the capacitive deionization (CDI) process. Due to the low surface area compared to the other nanocarbonaceous materials, CNFs performance as electrode in the CDI units is comparatively low. This problem has been overcome by prepar...
متن کاملA Comparative Study between Membrane Capacitive Deionization and Capacitive Deionization from Isotherms and Kinetics
Membrane capacitive deionization (MCDI) is a promising technique to achieve the desalination. This novel technique can largely improve the desalination efficiency of capacitive deionization (CDI) by introducing ion-exchange membranes into CDI. This paper presents a comparative study on the electrosorptive performances of CDI and MCDI based on single walled carbon nanotubes electrodes in NaCl so...

متن کاملEnergy breakdown in capacitive deionization.
We explored the energy loss mechanisms in capacitive deionization (CDI). We hypothesize that resistive and parasitic losses are two main sources of energy losses. We measured contribution from each loss mechanism in water desalination with constant current (CC) charge/discharge cycling. Resistive energy loss is expected to dominate in high current charging cases, as it increases approximately l...
