“…When the microwave radiation is stopped, the dielectric molecules do not move, the heating stops, and no heating is carried out. At the same time, there will be no slow heating reaction and waste heat phenomenon, which makes the process easier to control [11].…”

Activated carbon (AC) can concentrate and transfer pollutants using its own adsorption capacity. Waste AC is a kind of solid waste, its adsorption capacity of pollutants is greatly reduced after adsorption saturation. If handled improperly, it will cause secondary pollution to the environment. Therefore, it is necessary to regenerate the waste AC to restore its adsorption performance and reduce environmental pollution and resource waste. Microwave regeneration technology is of great research value because of its low energy consumption, time saving and high efficiency. Based on the characteristics of microwave heating and regeneration mechanism, this paper summarizes the advantages of microwave regeneration compared with conventional heating regeneration, and the application status of microwave technology in the regeneration of waste AC was reviewed. The influence of different types of pollutants adsorbed by AC, the change of control conditions for microwave regeneration of AC and the characteristics of AC itself on microwave regeneration were briefly described. And the development direction of microwave regeneration of AC in the future is also prospected.

“…Besides, new configuration such as funnel-andgate has been used to solve the problems of blocking and loss of permeability during PRB operation (Hosseini et al, 2011). Microwave based regenerating technology was adopted in Cs-contaminated groundwater treatment PRB to resolve the efficiency reduction due to GAC saturation (Falciglia et al, 2020). All of the above innovations extended the flexibility and longevity of PRBs.…”

“…Falciglia et al [100] investigated the potential use of a novel microwave-based regenerating permeable reactive barrier (MW-PRB) system for the removal of cesium (Cs) from groundwater with the use of activated carbon as an adsorbent in both batch experiments and column MW-regeneration experiments. The results showed that 80% removal of Cs was achieved with the column experiments when activated carbon was irradiated for 15 min.…”

Purpose of Review This paper reviews various low-cost treatment techniques such as adsorption, permeable reactive barrier, and biological techniques for the simultaneous removal of chemical and microbial contaminants from groundwater and discusses treatment mechanisms of different treatment techniques. This paper also discusses the challenges of groundwater treatment, how to choose the appropriate treatment technique, and cost analysis of groundwater treatment. Recent Findings Various treatment technologies have been used for the treatment of groundwater: physical, chemical, and biological technologies with different success rates. In the literature, various adsorbents have been successfully synthesized from low-cost and environmentally friendly materials. Adsorption is considered an efficient treatment technique for the removal of both toxic elements and pathogens by utilizing different adsorbents. For example, the nanostructures of MgO with a BET surface area of up to 171 m2/g obtained a very high adsorption capacity of 29,131 mg/g for fluoride ions in water, while the incorporation of iron in activated carbon has improved its adsorption capacity to 51.3 mg/g for arsenic. Moreover, certain adsorbents have shown the capability to remove 99% of the rotavirus and adenovirus from groundwater. Summary Groundwater resources are contaminated with toxic metals and pathogens. Therefore, water treatment technologies should be evaluated for their efficiency to remove such contaminants. Determination of the most cost-effective and efficient treatment technique is not an easy task and requires the understanding of various aspects such as the contaminants present in water, the reuse options considered, and cost analysis of the treatment technique.
