Runoff water loaded with road de‐icing salts: Occurrence, environmental impact and treatment processes
To ensure road safety during winter, it is necessary to use de‐icing salts. However, the detrimental effects of these salts on aquatic ecosystems, vegetation, lakes, ground and surface water, and soils have become a major concern in recent years. This review aims to discuss the adverse environmental impact of using de‐icing salts on the environment and explore current conventional methods used for managing and treating runoff water. Additionally, desalination techniques in terms of their effectiveness and energy requirements have been discussed. By comparing energy costs and considering the salinity levels of runoff water containing de‐icing salts, electrodialysis as a potential technique is introduced to be combined with conventional approaches for removing and recovering salt from runoff water loaded from road de‐icing salt.
期刊介绍:
Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including:
-Water and wastewater treatment for agricultural, municipal and industrial applications
-Sludge treatment including processing, storage and management
-Water recycling
-Urban and stormwater management
-Integrated water management strategies
-Water infrastructure and distribution
-Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
