“…Compared to the first operation of the CW-B in 2015, resulting in 99.86% of detergent removal [26], there was a 2.76% decrease in detergent removal. However, both values of detergent removals in the CW-B and CW-S are higher than the result of the previous study by [31] which obtained 90% detergent removal, using S. americanus plants, and applying HRT for 15 days. Once again, the old CW-B exhibited high performance in removing such pollutants, in terms of detergents.…”

Compared to the conventional wastewater treatment plants, constructed wetlands (CWs) are low-cost and affordable green technologies for treating many types of wastewater. This study aimed to evaluate the sustainability of an old-single CW, after four years of operation, and compare its performance with a new-smaller CW, using Cyperus alternifolius plant and applying Hydraulic Retention Time (HRT) for one day. Two artificial wetlands, namely CW-B and CW-S, were used with dimensions (length x width x height) of 170 x 70 x 70cm and 71 x 42.5 x 52.5cm, respectively. The first operation of the CW-B was in September 2015 and the CW-S was in April 2019. Several concentrations of household greywater influent were loaded into the CWs to analyze their performance. Two aeration pipes were installed in the wetland system to increase the oxygen level in the systems. Water quality parameters namely Biological Oxygen Demand (BOD), Total Suspended Solid (TSS), detergent, and Dissolved Oxygen (DO) were laboratory tested before and after treatment. Research carried out during April to October 2019 resulted in the mean removal efficiencies for CW-B and CW-S being 94.13% and 96.84% for BOD; 95.04% and 95.62% for TSS; 97.11% and 94.61% for detergent; and 99.5% and 79.7% for DO increase, respectively. These findings indicate that the removal efficiencies of those parameters in both wetlands were not significantly different. Hence, the system of the old CW-B wetland still keeps a good working process. Referring to the national standards of water quality, the greywater effluents were safely discharged into water bodies and could be used for irrigation needs. A further study needs to be developed to maximize the detergent removal to meet the existing standard for hygiene sanitation. These results suggest that CWs are becoming a sustainable solution for the treatment of greywater at the household level and finally contributing to minimizing the pollution of water.

“…Waste water will directly replace the air cavities contained in the substrate. The presence of plants in HSSFCWs increases sedimentation by slowing down the water velocity thereby allowing suspended material to settle [31].…”

“…Some previous studies mention the success of the combination of biofilter as a pretreatment and constructed wetland as subsequent treatment in domestic wastewater treatment [25]. Integrated system constructed wetlands (CWs) and biofilter be a relevant alternative in treating wastewater because it is efficient in terms of installation, operational and maintenance aspects [31]. This study aims to determine the performance of a combination of biofilter and constructed wetland treatment systems in treating batik wastewater.…”

Wastewater produced during the batik production process contains toxic and difficult to decompose chemicals which can cause an increase in power of hydrogen (pH), biological oxygen demand (BOD), chemical oxygen demands (COD), total suspended solids (TSS), and heavy metals. Wastewater produced from batik or the textile industry is generally an organic compound that is difficult to decompose, which can cause environmental pollution, especially from the aquatic environment. The effluent from the batik industry in the boiling process does not meet the quality standards set by Regulation of the Minister of Environment of the Republic of Indonesia No. 5/2014 on wastewater quality standards. Natural wastewater treatment systems such as constructed wetlands (CWs) and biological sand filter be a relevant alternative in treating wastewater because of its efficiency, cost and operation. This research aims to treat batik industry wastewater using biofilter-horizontal sub surface flow constructed wetlands (HSSFCWs) integration. The results showed a decrease in efficiency for each COD, TSS, and oil and fat parameters 72.67-86.67%; 95.85-98.18%; dan 79.47-90.04%. The results of statistical analysis showed that there was a significant influence between biofilter performance and biofilter-HSSFCWs integration in a period of 3 days, 5 days and 7 days with the dependent variable. The water from batik industry waste processing still exceeds the established quality standards so that the treated water is not allowed to be discharged into water bodies. The treated water also cannot be designated by the community because it does not meet the water quality criteria in the specified water class.

“…Detergents, which may consist of surfactants, adjuvants, bleaches, and several additives functionality, counteract the external tension of the aquatic to form micelles and eradicate grime. Surfactants are in control of the cleaner influence in washing products, and they can be categorized into four groups: anionic, cationic, non-ionic, and amphoteric [3]. For many years, Sodium Lauryl Sulfate (SLS), an anionic detergent, has been utilized as an antibacterial surfactant [4], [5].…”

“…As stated in recent works, the wetland process has shown promising applications for treating grey wastewater with a high detergent concentration. For example, in linear alkylbenzene sulfonate (LAS), which is another common anionic surfactant, the removal efficiency was measured at 77% after 15 days of HRT and the treated water was used for gardening [3]. Another research was focused on horizontal flow wetlands cultivated with helophytes, graminoids, tropical, and subtropical plants.…”

Suspended substances in car washes can often be easily removed by physicochemical processes. The main problem is to remove dissolved substances such as detergents from the water. In this study, a biodegradable substance Sodium Lauryl Sulfate (SLS) was removed from the car wash wastewater by the use of Phragmites australis in the subsurface constructed wetland. For this study, 4 plexiglass reactors having an effective volume of 10.8 L with the dimensions of 15cm×45cm×20 cm were used. The experiments were conducted with vegetation which was called SCW and without vegetation which was named control group (CG), as two groups. A serial connection of two reactors was performed for each group. Up to 90% detergent removal was observed with the vegetation in the SCW with a loading rate of 75 L/(m2.d) The effluents quality showed that the treated water can be reused carwash or irrigation for landscaping.
