“…However, the rates of Cu and Zn absorptions are also dependant on the inlet concentrations. For example, Kanagy et al (2008) showed that at very low inlet concentration of 0.89 mg/L, Schoenoplectus californicus and T. latifolia could remove nearly 89% of Cu in a wetland. In general, T. domingensis has shown to tolerate heavy metals and to maintain the contaminant removal efficiency of the CW, in that metal concentration (Cr, Ni and Zn) and total phosphorus have been reported to be significantly higher in tissues of plants growing at the inlet in comparison with those from the outlet and natural wetlands (Hadad et al, 2010).…”

An artificial wetland was computationally modelled using STELLA®, a graphical programming tool for an Au-Cu mine site in Central-west NSW, the aim of which was to offer a predictive analysis of a proposed wetland for Cu, Zn and Mn removal using Typha domingensis as the agent. The model considers the important factors that impact phytoremediation of Cu, Zn and Mn. Simulations were performed to optimise the area of the wetland; concentration of Cu, Zn and Mn released from mine (AMD); and flow rates of water for maximum absorption of the metals. A scenario analysis indicates that at AMD = 0.75mg/L for Cu, Zn and Mn, 12.5, 8.6, and 357.9 kg of Cu, Zn and Mn, respectively, will be assimilated by the wetland in 35 years, which would be equivalent to 61 mg of Cu/kg, 70 mg of Zn/kg and 2,886 mg of Mn/kg of T. domingensis, respectively. However, should Cu, Zn and Mn in AMD increase to 3 mg/L, then 18.6 kg of Cu and 11.8 kg of Zn, respectively, will be assimilated in 35 years, whereas no substantial increase in absorption for Mn would occur. This indicates that 91 mg of Cu, 96 mg of Zn and 2917 mg of Mn will be assimilated for every kg of T. domingensis in the wetland. The best option for Cu storage would be to construct a wetland of 50,000 m 2 area (AMD = 0.367 mg/L of Cu), which would capture 14.1 kg of Cu in 43 years, eventually releasing only 3.9 kg of Cu downstream. Simulations performed for a WA of 30,000 m 2 indicate that for AMD = 0.367 mg/L of Zn, the wetland captures 6.2 kg, releasing only 3.5 kg downstream after 43 years; the concentration of Zn in the leachate would be 10.2 kg, making this the most efficient wetland amongst the options considered for phytoremediating Zn. This work will help mine managers and environmental researchers in developing an effective environmental management plan by focusing on phytoremediation, with a view at extracting Cu, Zn and Mn from the contaminated sites.

“…Dari beberapa studi yang dilakukan untuk mengolah air terproduksi dengan sistem constructed wetland, diketahui bahwa constructed wetland dapat menyisihkan diantaranya COD, BOD 5 , mineral minyak, TKN (Ji et al, 2002), TDS, toksisitas (Murray-Gulde et al, 2003) dan logam berat (Kanagy et al, 2008).…”

Abstrak: Air terproduksi merupakan produk sampingan dari proses produksi indutsri minyak dan gas. Kualitas air terproduksi beragam, namun secara umum memiliki konsentrasi total dissolved solid (TDS) yang relatif tinggi. Pada konsentrasi tinggi, Total Dissolved Solid (TDS) dapat menyebabkan perubahan rasa pada air, pengendapan mineral dan korosi. Teknologi wetland dapat menjadi alternatif pengolahan yang mudah diterapkan dan relatif murah. Penambahan aerasi diharapkan mampu meningkatkan efisiensi penyisihan TDS. Tujuan dari penelitian ini adalah untuk melihat pengaruh penambahan aerasi pada wetland, waktu detensi/waktu tinggal yang optimum, dan penambahan Cyperus nutans yang digunakan sebagai vegetasi terhadap penyisihan TDS dan parameter lainnya. Sejauh ini, hasil penelitian menunjukkan bahwa penambahan aerasi dapat meningkatkan efiensi penyisihan TDS dibandingkan dengan penelitian sejenis yang tidak menggunakan aerasi. Hasil penelitian menunjukkan bahwa efisiensi penyisihan TDS pada reaktor dengan penambahan aerasi lebih tinggi dibandingkan dengan reaktor yang diaerasi.

Pilot-scale experiments were performed to investigate the role of equalization basins used with constructed wetland systems for treatment of flue gas desulfurization (FGD) waters. Analysis of FGD water samples indicated that aqueous concentrations of Hg, As, and Se remained constant or changed very slightly in a pilot-scale equalization basin during a 24-h hydraulic retention time (HRT). No change in toxicity of FGD water occurred after one HRT. FGD particles were predominantly silt size, and approximately 99% of particles suspended in FGD water settled to the bottom of a 2.5-m-deep equalization basin during the first 4 h of the 24-h HRT. Approximately 90% of the total As, and smaller percentages of Hg and Se, in FGD water and particles were removed by particle settling in the equalization basin. Results of this investigation lend support to the use of equalization basins for treating FGD waters in constructed wetland treatment systems.
