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 کاملAdsorption Process for Wastewater Treatment by using Coconut Shell
Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from wastewater. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. The adsorption f...
متن کاملEfficiency of electrical coagulation process using aluminum electrodes for municipal wastewater treatment: a case study at Karaj wastewater treatment plant
Background: The reuse of treated municipal wastewater is an important source of water for different ,purposes. This study evaluated the efficiency of the electrocoagulation process in removing turbidity,a total suspended solids (TSS), chemical oxygen demand (COD), nitrate, and phosphate from wastewater at the treatment facility in Karaj, Iran. Methods: This experimental study was performed at ...
متن کاملPhotocatalytic degradation of an azo-dye on TiO2/activated carbon composite material.
A sequential adsorption/photocatalytic regeneration process to remove tartrazine, an azo-dye in aqueous solution, has been investigated. The aim ofthis work was to compare the effectiveness of an adsorbent/photocatalyst composite-TiO2 deposited onto activated carbon (AC) - and a simple mixture of powders of TiO2 and AC in same proportion. The composite was an innovative material as the photocat...
متن کاملAdsorption of Lead and Copper by a Carbon Black and Sodium Bentonite Composite Material: Study on Adsorption Isotherms and Kinetics
The efficiency of using a composite of carbon black and sodium bentonite in treating drinking water contaminated with lead and copper ions was analysed. The effects of pH, contact time, concentration and adsorbent dosage using an adsorbent composite of 20 % sodium bentonite and 80 % carbon black were studied. The adsorption data was tested with respect to Langmuir, Freundlich and Temkin iso...
