Nickel removal from electroplating industry wastewater: A bamboo activated carbon
Water is prime requirement for surviving of any living beings. The existence of surface water and groundwater sources are used for domestic, agriculture and industrial purposes in all over the world. Fresh water from both the water sources is highly contaminated in recent years because of rapid population growth, modern agriculture and industrial growth. Among them, contamination of water sour...
متن کاملChromium removal and water recycling from electroplating wastewater through direct osmosis: Modeling and optimization by response surface methodology
Background: Considering the carcinogenic effects of heavy metals, such as chromium, it is essential to remove these elements from water and wastewater. Direct osmosis is a new membrane technology, which can be a proper alternative to conventional chromium removal processes. Methods: The wastewater samples were collected from an electroplating unit, located in Alborz industrial city, Qazvin, Ir...
متن کاملPreparation and characterization of poly (ethersulfone) nanofiltration membranes for amoxicillin removal from contaminated water
Nowadays, antibiotics such as amoxicillin have been entered in water bodies. Nanofiltration has been proposed as an attractive technology for removal of antibiotics from aquatic environment instead of conventional wastewater treatment. In this paper, novel asymmetric flat sheet nanofiltration membranes were prepared via immersion precipitation technique and by using the poly(ethersulfone)/Brij®...
متن کاملNickel electroplating for nanostructure mold fabrication.
We demonstrated a practical process of fabricating nickel molds for nanoimprinting. Dual-side polished glass is chosen as the substrate on which nickel nanostructures are successfully electroplated. Photonic crystal structures with 242 nm diameters and other nanoscale pillars down to 9 nm diameters are achieved over a large area. The electroplating parameters are investigated and optimized. Thi...
متن کاملRemoval of Hexavalent Chromium from Electroplating Wastewater by Electrocoagulation with Iron Electrodes
The performance of electrocoagulation using iron electrodes for the removal of hexavalent chromium from synthetic aqueous solutions and actual industrial electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, applied current density, initial metal ion concentration, COD and time of electroprocessing were investigated. The optimum pH was f...
