Development of alumina/iron oxide nanocomposites as adsorbents for arsenic and fluoride removal from aqueous solutions: Process Optimization
The study was designed to optimize the process for the synthesis of alumina/ iron oxide nanocomposites and to investigate their potential as a sorbent to remove fluoride and arsenic from contaminated water. The nanocomposites had [...]
Ionic Diodes in Water Desalination & Purification
Ionic rectifiers (or ionic diodes) work like electronic diodes, but allow ion flow to be controlled. We have developed novel ionic diode devices based on ionomer and polymer materials coated onto microholes to typically 5 [...]
Resilient water treatment technologies and challenges for the removal of emerging contaminants – Perfluorinated compounds
Due to their global presence, persistence, and adverse health effects, perflurinated compounds (perfluoroalkyl and polyfluoroalkyl substances PFASs) have become major chemical of concern for drinking water supplies worldwide. Presence of these PFCs in various geographical [...]
Electroflox® Pilot plant for primary wastewater treatment of leachate
Marriaga-Cabrales N., Machuca-Martinez F., Donneys-Victoria D., Alvarez-Pugliese C.E., UNIVERSIDAD DEL VALLE, CO
Landfill leachates are liquid effluents that contain a high pollutant load and represent a serious environmental challenge for the disposal sites; Even after the useful life of a landfill, leachates continue to be generated for [...]
Enhancement of Heat Transfer Coefficient Using Fe2O3 –Water Nanofluids
Research efforts have been made to increase the heat transfer rate, energy, and efficiency. Some of these efforts include the application of fins, compact heat exchangers, microchannel, and many others. Recently, nanofluids have been introduced [...]
Electrocapacitive Desalination of Brackish Water Using Biochars
The principle of capacitive deionization (CDI) has been known for some time, as a spin-off of electrochemical capacitance. Instead of storing energy, the purpose of CDI is to store (temporarily) salt, extracted from the water. [...]
Application of a Novel Cold Atmospheric Plasma for Water Decontamination
Kim H., Izadjoo M., Izadjoo S., Truong H., Izadjoo M., Izadjoo S., Trideum Biosciences and ChiScan LLC, US
In recent years, non-thermal atmospheric plasma has been considered as potential decontamination technology. The plasma can interact with ambient atmosphere and generate a variety of reactive species such as ozone, hydrogen peroxide, radical, atomic and [...]
Metals disinfection of E. coli in synthetic groundwater and effects of varying water chemistry
The sustainable access to clean and safe drinking water remains as global challenge as large numbers of people still consume water that is not safe. Diarrhea; a preventable waterborne disease remains the major cause of [...]
Energy Generation from Carbonaceous and Nitrogenous Pollutants via Ammonium, Methane, and Carbon Dioxide Reformation
An unprecedented integrated electrodeionization–solid oxide fuel cell (EDI–SOFC) system is developed for energy capture from carbonaceous and nitrogenous pollutants from wastewater. The feature of this system is that both carbonaceous and nitrogenous pollutants can be [...]
Effect of polymer ratio on nZVI loading onto electrospun nanofiber mat for mitigating groundwater contaminants
Nanoscale zero-valent iron (nZVI) has been widely used for the reduction of halogenated organics and heavy metals in the groundwater. However, individual nZVI particles are mobile and prone to aggregate, thereby reducing the reaction sites [...]
