Urban Farm DB summary
The WETWALL design concept proposes a unique ecotechnology for secondary wastewater treatment at an urban scale, integrating constructed wetlands and modular living walls into a modular living wall hybrid flow. This article reviews existing living walls treating wastewater, focusing on nitrate and phosphate removal, and presents the WETWALL concept, including component selection (plants, substrate) and operational strategies. It also discusses potential interactions with the urban environment, aiming to substantiate WETWALL's potential as an innovative urban wastewater treatment.
