Abstract

Aim: This study aims to determine the potency of horsetail plant to remove heavy metal concentration. Methodology and Results: Data was obtained from fifty-four (54) horsetails which were divided into three batches of 12, 18, and 24 plants respectively. Furthermore, the experimental method with the subsurface flow system treatment was used with two samplings for seven days. The results showed that the first, second and third batches gave a 6.83%, 10.28%, and 16.26% impact on reducing concentration of Fe respectively with an approximate average of 11%. Therefore, the detention time of the leachate constructed wetland reactors significantly reduced the Fe contaminant. Conclusion, significance, and impact of study: This research provides a solution to mitigate the environment by adopting the accumulator of Horsetail plants (Equisetem hyemale) in the constructed wetlands reactor experiment. From the three reactors approximately 0.03 mg/L of heavy metal iron was removed after a seven day run. Therefore, horsetail plant showed a positive impact in reducing environmental pollution, a trend adoptable in wastewater and leachate treatment technology in Indonesia.

Abstract

Leachate generated from municipal solid waste landfills contains various pollutants that may pose significant environmental risks if discharged without proper treatment. The increasing volume of waste and high rainfall intensity in tropical regions contribute to fluctuations in leachate quantity and quality, creating challenges for landfill management. This study aimed to design a leachate wastewater treatment plant (WWTP) for the Cilowong Landfill, Serang City, Indonesia, by integrating a Vertical Subsurface Flow Constructed Wetland (VSSF-CW) system with natural filtration units. The research employed a quantitative engineering design approach involving field observation, leachate characterization, hydrological analysis, rainfall frequency analysis, and hydraulic design calculations. Laboratory results showed that the average concentrations of Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) were 401.8 mg/L, 28.08 mg/L, and 765.6 mg/L, respectively. Hydrological analysis indicated that the maximum leachate discharge corresponding to a 10-year return period rainfall event reached 6,998.4 m³/day, while the average operational discharge was only 27.36 m³/day, highlighting the substantial influence of rainfall on leachate generation. Based on the design calculations, the proposed treatment system consists of an equalization basin with a volume of approximately 7,000 m³, a sedimentation basin of 600 m³, a constructed wetland unit of 260 m³, a filtration basin of 260 m³, and a separator basin of 130 m³. The integration of VSSF-CW and natural filtration is expected to enhance pollutant removal through sedimentation, adsorption, filtration, phytoremediation, and microbial degradation processes. The proposed design provides an environmentally friendly, cost-effective, and sustainable alternative for leachate treatment, particularly for landfills located in developing regions with tropical climatic conditions.
