Constructed wetland (CW) has gained popularity as an eco‐friendly technology for ease of operation and maintenance. This article critically reviews and summarizes the research carried out to date on several approaches for integration of CW with other methods of treatment, exploring several novel modes of operation and factors, to improve the remediation capacity of the CW system. The study shows that the use of different modes of aeration, recirculation of the effluent, hydraulic retention time, and organic loading rate not only improves the removal efficiency of the treatment system but also helps in reducing the surface area required for the system in the treatment of emerging contaminants. The integrated approach analysis gives an insight into the different technologies, which can be coupled with CW for fast, sustainable, and eco‐efficient treatment systems for different types of wastewater. Anaerobic technologies and microbial fuel cell (MFC) have the added advantage of energy generation apart from wastewater treatment, which helps in reducing carbon footprints. Optimization of pollutant treatment in wastewater and electricity generation by CW‐MFC has emerged to be an upcoming area of research. The study disseminates knowledge about the latest developments in the field of intensified CW technology with a focus on modifications and integrated systems, which help in identifying the potential areas of research worth addressing in the future.

Treated Wastewater Use for Maintenance of Urban Green Spaces for Enhancing Regulatory Ecosystem Services and Securing Groundwater

2022

View full text Add to dashboard Cite

Rising land surface temperature (LST), urban heat island (UHI) effects, and stress on surface-, processed-, potable-, and ground-water resources are some undesirable ecological changes due to rapid urbanization. Treating and reusing city-generated wastewater for maintaining urban green spaces (UGS) helps in reducing/preventing groundwater extraction, ensuring sufficient supply of potable water, and bringing down LST. However, the benefits of reusing treated wastewater in UGS for enhancing regulatory ecosystem services (RES) and ushering in a circular economy are yet to be realized. In view of these, the transportation costs of treated wastewater for irrigating the UGS of Panaji city—proposed to be developed as a smart city—were assessed. Field surveys were conducted at seven gardens/parks to collect the primary data on vegetation type (ground cover, hedge plants, and trees) and their daily water requirement. As the main focus of this study, a cost–benefit analysis of (a) drawing the groundwater using borewells versus use of treated wastewater from the city’s STP, and (b) two modes of treated wastewater transport: water tankers vs. pipeline was performed. Our analyses suggest that the copiously available 14 MLD treated wastewater from the STP, which meets all the safety standards, is far in excess of the current requirement of 6.24 MLD for watering the vegetation in all 17 parks/gardens in the city. Pipeline is an efficient (less energy, labor, and time) and economical (~47% more than water that is tanker-based) transportation mode. By utilizing the otherwise unused treated wastewater, which is processed at a cost of over USD half a million annually, the RES offered by the use of treated wastewater are (a) partially curtailing a combined loss of ~16 MLD due to the extraction of groundwater plus evapotranspiration (@8.86 mm d−1) from Panaji city’s 1.86 km2 UGS, and (b) reduction in LST ~3–4 °C in all of Panaji city. In addition, with the proficient and sustainable management of UGS and the meeting of many UNSDGs, the enhanced vegetation growth plus elevated carbon sequestration rates in the UGS are possible through the reuse of treated wastewater.
