“…With low external energy requirements, it improves water quality by means of a combination of physical, chemical, and biological processes (Ruiz, 2007). The last few years showed that artificial or constructed wetlands were frequently used to treat wastewater due to their low-cost operation and maintenance, low energy consumption and ease of operation (Aboukila & Elhawary, 2021). It consists of vegetation, substrates, microorganisms, and soil components to support the water treatment process (Abou-Elela, 2019; Wijaya & Soedjono, 2018a).…”

With the burgeoning population, the community activities, such as laundering, washing, or even bathing, have expanded along the irrigation canal. Consequently, some chemicals from those activities are released and pollute the water body. Besides, the discharge of wastewater into the irrigation system is also an issue of public health concern, because it creates an environment conducive to the reproduction of any pathogenic agent. Using candung as constructed wetlands (CW)-like to treat the irrigation water in rice paddies would be an interesting tool for removing pollutants from the irrigation water. Candung, as a locally used CW in Bali Island, has been applied in the rice field long time ago. The present study aimed to examine candung as a local attached CW or treating irrigation water and analyse the community awareness regarding the candung application. The result showed a positive effect of candung in maintaining the water quality parameters, such as TSS, BOD, COD, and nutrients with certain aquatic plants (Nelumbo nucifera, Nymphaea tetragona, and Pistia stratiotes). The knowledge, behaviour, and action of the local subak community were still limited, whereas they had positive perceptions and responses about candungthe potential of candung as an agrotourism attraction in the village as well.

Free water surface constructed wetlands (FWSCWs) for the treatment of various wastewater types have evolved significantly over the last few decades. With an increasing need and interest in FWSCWs applications worldwide due to their cost-effectiveness and other benefits, this paper reviews recent literature on FWSCWs' ability to remove different types of pollutants (i.e., nutrients, heavy metals, antibiotics, and pesticides) that may co-exist in wetland inflow, and discusses approaches for simulating hydraulic and pollutant removal processes. A bibliometric analysis of recent literature reveals that China has the highest number of publications, followed by the USA. The collected data show that FWSCWs can remove an average of 61.6%, 67.8%, 54.7%, and 72.85% of inflowing nutrients, heavy metals, antibiotics, and pesticides, respectively. Optimizing each pollutant removal process requires specific design parameters. Removing heavy metal requires the lowest hydraulic retention time (HRT) (average of 4.78 days), removing pesticides requires the lowest water depth (average of 0.34 meters), and nutrient removal requires the largest system size. Vegetation, especially Typha spp. and Phragmites spp., play an important role in FWSCWs' system performance, making significant contributions to the removal process. Various modeling approaches (i.e., black-box and process-based) were comprehensively reviewed, revealing the need for including the internal process mechanisms related to the biological processes along with plants spp., that supported by a further research with field study validations. This work presents a state-of-the-art, systematic, and comparative discussion on the efficiency of FWSCWs in removing different pollutants, main design factors, the vegetation, and well-described models for performance prediction.
