Abstract

Wastewaters play a significant role in the negative impact of phosphorus on the environment, such as eutrophication. However, phosphorus is a limiting nutrient essential for life which has gained global attention on productive technologies for phosphorus recovery. Several technologies have been developed for phosphorus removal and recovery from wastewater to help alleviate phosphorus loss to the environment. Capacitive deionization technology, which was earlier developed for water desalination and ion removal, is actively being explored for its ability to remove phosphorus from wastewater. This review describes capacitive deionization technology (CDI) and its various types. Significant attention is given to the use of CDI technology for phosphorus/phosphate removal and recovery from wastewater. Some studies on phosphorus removal or recovery by CDI are summarized. This review also discusses our perspective on the CDI technology for phosphorus removal from wastewater. This paper informs researchers of the work done on using CDI for phosphorus removal from wastewater and the need for more studies in the application of CDI and phosphorus removal.

Keywords: capacitive deionization, phosphorus ion removal, wastewater, phosphorus recovery
