Energy generation by reverse electrodialysis

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In this work, the process of generating electricity from the water salinity gradient (RED) using the Russian produced ion exchange membranes MK-40 and MA-41 was investigated. The experiments were carried out with a saturated brine of sodium chloride in a chamber with salt water and with a solution of sodium chloride with a ...

α‐Al2O3 Networks on MLG Membranes for Continuous Lithium Ion Extraction from Artificial Sea Water with Enhanced Selectivity and Durability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An α‐Al2O3‐decorated multilayer graphene membrane enables highly selective lithium ion extraction from artificial seawater via electrodialysis. The confined ion channels and competitive ion transport dynamics enhance lithium selectivity, achieving 88.9% purity and 88.6% recovery over three extraction cycles while maintaining stable ion flux.

Irrigation using slightly saline water from emerging desalination technologies as a solution to short‐term drought

PLANTS, PEOPLE, PLANET, EarlyView.
With global weather patterns becoming more extreme and unpredictable, sourcing reliable irrigation water is vital for improving food security and conserving drinking water in drought‐prone areas. Emerging desalination technologies, which are still in the development phase, could potentially provide large quantities of slightly saline water for ...

Feasibility Study of an Electrodialysis System for In-Home Water Desalination and Purification in Urban India [PDF]

, 2015
Desalination of high salinity water is an effective way of improving the aesthetic quality of drinking water and has been demonstrated to be a characteristic valued by consumers. Across India, 60% of the groundwater, the primary water source for millions,

Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production

PLANTS, PEOPLE, PLANET, EarlyView.
Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...
