{"cited_by_count":449464,"description":"This cluster of papers focuses on the application of constructed wetlands for the treatment of various types of wastewater. The research covers topics such as nutrient removal, microbial processes, phosphorus and nitrogen removal mechanisms, plant and microbial effects, and the efficiency of different wetland systems. It also includes reviews on the sustainability and development of constructed wetlands for wastewater treatment.","display_name":"Constructed Wetlands for Wastewater
