“…The same P d,max (~0.38 W/m 2 ) was recorded by another pilot RED fed with treated water (anaerobic-oxix activated sludge process) at conductivity of 1.0-2.5 mS/cm and seawater at 50 mS/cm [429]. Actually, the seawater solution was obtained by mixing a desalination brine with the treated water.…”

This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and other treatments with significant environmental benefits. ED technologies can be used in operations of concentration, dilution, desalination, regeneration, and valorisation to reclaim wastewater and recover water and/or other products, e.g., heavy metal ions, salts, acids/bases, nutrients, and organics, or electrical energy. Intense research activity has been directed towards developing enhanced or novel systems, showing that zero or minimal liquid discharge approaches can be techno-economically affordable and competitive. Despite few real plants having been installed, recent developments are opening new routes for the large-scale use of ED techniques in a plethora of treatment processes for wastewater.

“…However, most of the research was done at a lab scale, and the requirement of scale-up cannot be ignored. Out of all the processes mentioned in Table , biological methods are considered the most advanced and efficiently applicable to wastewater. , The progress in photonic methods depends on novel and effective catalysts. − Processes using the electric potential are somewhat mature and commercialized in different areas, but their application for producing hydrogen from wastewater is still under research. − …”

Hydrogen Economy and Role of Hythane as a Bridging Solution: A Perspective Review

2021

View full text Add to dashboard Cite

Molecular hydrogen is the most optimistic solution for achieving a carbon-neutral energy economy, and it requires scientific intervention for its production, storage, and transportation. In the present time, hydrogen is produced primarily from conventional fossil fuels. Hydrogen production from natural gas using partial oxidation and steam reforming processes is a relatively mature process. However, several modifications and improvements are being researched. Hydrogen generation from potential renewable and biological sources such as water splitting and biomass conversion are propitious approaches. Hydrogen is one of the smallest molecules, and the volumetric efficiency of its storage is quite poor. The creative and innovative ways for molecular hydrogen storage, including pressurized, liquified, physically adsorbed, chemically adsorbed, and in the form of gas hydrates, are being investigated. The delay in developing a systematic and mature hydrogen economy is mainly due to challenging storage conditions and the safety aspect of its transportation. Hythane, a patented mixture of hydrogen and natural gas, can act as a bridge for the hydrogen economy by sharing the current natural gas infrastructure. This review delivers an extensive understanding of the properties of hythane fuel with a brief history. Hydrogen addition can increase NO x emissions due to exceptional heat generation that can be solved to a certain extent with the approach of inventive technologies developed for internal combustion engines, including three-way catalyst, lean burn combustion, exhaust gas recirculation (EGR), and direct fuel injection (DFI).
