A 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 کاملMembrane bioreactors for metal recovery from wastewater: A review
The need to remove or recover metal ions from industrial wastewaters is both financially and environmentally driven, financially in terms of cost savings through metal reuse or sale, and environmentally as heavy metal toxicity can affect organisms throughout the food chain, including humans. Current removal strategies are mainly based on physico-chemical techniques such as filtration, chemical ...
متن کاملMetal Recovery from Leached Plating Sludge
he 23 US. Army installations engaged in plating employ a variety of techniques to treat wastewater. While some sites have implemented recovery and T reuse, a majority still find it advantageous to precipitate the metals and discharge the wastewater. Sludge is collected in clarifiers, treated by gravity thickening, then dewatered in pressure or vacuum filters, lagoons or drying beds. The dewater...
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...
متن کاملBio‐palladium: from metal recovery to catalytic applications
While precious metals are available to a very limited extent, there is an increasing demand to use them as catalyst. This is also true for palladium (Pd) catalysts and their sustainable recycling and production are required. Since Pd catalysts exist nowadays mostly under the form of nanoparticles, these particles need to be produced in an environment-friendly way. Biological synthesis of Pd nan...
