“…Perdana et al (2020) cited the decay of plant organs inside constructed wetland systems and a low hydraulic retention time (HRT) as the primary causes of the negative BOD and COD removal. Plant residues in the substrate increased the organics loading in the facility, whereas inadequate contact times limited the anaerobic conditions within the media [44]. Negative removal rates of nutrients were also reported in the constructed wetlands studied by Land et al (2016).…”

The efficiency of nature-based facilities is mostly evaluated in terms of their pollutant removal capabilities; however, apart from water purification functions, constructed wetlands also perform ecological, cultural, and environmental education functions. A multi-criteria performance index was developed in this study to evaluate the overall efficiency of constructed wetlands. A total of 54 constructed wetlands installed across South Korea were monitored to evaluate the pollutant removal performance of the facilities. A comparison between the conventional pollutant removal-based evaluation and the developed multi-criteria index was also performed to determine the key changes in the results of evaluation when different methods are employed. Among the different types of wetlands studied, hybrid systems were found to be the most effective in terms of pollutant removal due to their complex configurations and functions. Newly constructed treatment wetlands have unstable performance and thus, a stabilization period ranging from two to five years is required to assess the facility’s pollutant removal capabilities. As compared to the conventional pollutant removal-based efficiency evaluation, the comprehensive evaluation method provided a more strategic tool for identifying the facilities’ strengths and weaknesses. Generally, the multi-criteria performance index developed in this inquiry can be utilized as a general tool for evaluating the sustainability of similar nature-based facilities.

“…This result was in line with Zhu et al (2013) which reported that phosphorus removal efficiency ranged from 78 to 84% using a medium consisting of four layers; 10cm of gravel placed at the bottom, followed by 10 cm of cinder, 12cm of ceramsite and 6cm of sand on the top and planted with Canna indica L. Meanwhile, Li et al (2013) obtained 85 % phosphorus removal efficiency using water quenched slag (WQS) media planted with Canna indica L when loaded with domestic sewage. Perdana et al (2020) reported that this value reached 91% using gravel media planted with several plants. J o zwiakowski et al ( 2017) obtained a phosphorus removal efficiency of 97 % using different particle sizes with diameter 5-10mm of carbonate-silica rock media.…”

The performance efficiency in constructed wetlands (CWs) technology is primarily affected by the media material and the types of plants used. Recently, investigations into the usage of local materials and plants in CWs has increased. Pumice is a material which is potential used as a media. However, research on amendment of pumice with other media in CWs is still limited. Therefore, this study aims to evaluate the potential of pumice amended with sand media and planted with lemongrass (Cymbopogon citratus) in CWs to remove organic matter, suspended solids, nutrients, and coliform. The adsorbents were characterized using X-ray diffraction, FTIR and XRF followed by adsorption experiments for PO 4 -P. Furthermore, Six vertical flow (VF) mesocosms with a diameter of 10.2cm and 55cm depth were established over six months. The treatments were based on percentage of sand media amended with pumice and planted with lemongrass. Furthermore, the barren media were applied to investigate the effect of lemongrass. The loading rate of domestic wastewater into the VF mesocosms was 2 L/day while inflows and outflows were determined for nutrients, organic matter, suspended solids and coliform. The adsorption of PO 4 -P followed the Langmuir model with adsorption capacity was 0.089 and 0.067 mol/g for pumice and sand, respectively. The results also showed that the removal efficiency of TSS, COD, NO 3 -N, NO 2 -N, PO 4 -P and total coliforms were in the range of 93.7-97.3 %, 52-83 %, 63-86 %, 51-74%, 81-88 % and 92-97 %, respectively. Based on the results, the highest removal efficiency was observed in the sand media amended with 50 % pumice and planted with lemongrass, while the lowest was found in the barren sand media.

“…The results are tabulated in Tables 1 and 2. The removal e ciency of the BOD, COD, and TN has been calculated from the above results by using an equation that is Where Cin (mg/L) is the inlet concentration and Cout (mg/L) is the outlet concentration (Perdana 2020). The percentage of removal e ciency is tabulated in Tables 3 and 4.…”

Water recycling is essential to reduce water scarcity in India due to population growth. Water for consumption is most crucial, it is equally important to provide water for irrigation to increase food production and livestock husbandry, to ensure food security for the increasing population. This paper deals with recycling and reuse of residential greywater (Wastewater from bathtubs, showers, hand washing basins and washing machines, kitchen sinks except for wastewater from toilet flushing system). In domestic wastewater 2/3 of wastewater is considered greywater. This greywater can be treated and reused for gardening, flushing, construction purposes, etc. Conventional treatment systems are highly sensitive and necessitate good monitoring and efficient process control. Hence, the natural wastewater treatment options such as treatment using aquatic plants are becoming quite attractive in this view. In this study, the sugarcane variety of CO86032 and CO 15027 were used for phytoremediation. Coarse aggregate (20 mm), Brick jelly (20 mm), and Red soil mixed with Coir pith (1/3 volume-based) were used as filter material of laboratory-scale constructed subsurface wetland system having size 0.92 m, 0.61 m, and 0.45 m of length, breadth, and depth respectively. The removal efficiency of biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), and Total Nitrogen (TN) was 77–89%, 66–81%, 70–91%, and 68–84% achieved during a retention time of 2 hours to 48 hours.
