“…Lahan basah buatan terbagi menjadi dua tipe yaitu lahan basah buatan tanaman air muncul dan tanaman air mengapung. Tanaman air muncul yaitu memiliki kedalaman yang sangat dangkal, berada pada kisaran 0,1 -0,6 m. (Abidi, 2007) sedangkan tanaman air mengapung dapat mencapai kedalaman 0,5 1,8 meter. Teknologi lahan basah buatan dipilih untuk menangani permasalahan limbah domestik dikarenakan teknologi ini merupakan teknologi yang murah biayanya, tidak memerlukan teknologi canggih untuk mengoperasikannya, dan tidak memerlukan operator khusus dalam mengoperasikannya (Stottmeister, 2014).…”

Sebagian besar air dipakai sebagai air untuk pembilas, sebagai contoh air bersih yang digunakan untuk mandi dan cuci. Namun, kebutuhan akan air baku yang besar tidak diikuti dengan persediaan air baku, baik secara kuantitas maupun kualitas. Salah satu cara untuk mengatasi masalah ini adalah dengan memanfaatkan kembali (reuse) efluen hasil pengolahan air limbah. Pada penulisan ini cara mengelolah air limbah domestik menggunakan sistem lahan basah buatan yang menggunakan tanaman air dalam skala lapangan. Penulisan ini bertujuan mengetahui efisiensi penurunan kadar Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) dan Dissolved Oxygen (DO) yang terkandung dalam limbah cair domestik pada suatu daerah. Metode penulisan dengan cara mengaklamatisasi tanaman selama 12 hari sebelum ditanamkan ke lahan basah buatan kemudian mengukur efisiensi penurunan kadar efluen. Hasil percobaan menunjukkan bahwa dengan menggunakan tanaman air dalam sistem lahan basah buatan dapat penyisihan kandungan pencemar dalam air limbah dengan waktu tinggal 2 hari. Keunggulan pengolahan air limbah dengan sistem ini selain kualitas hasil air pengolahan yang sesuai baku mutu air limbah domestik juga dapat meningkatkan kualitas tanah.

“…In this study, Thalia genicualata vegetation showed a high removal efficiency of BOD (85%). The BOD removal in a CW is generally high because the organic components are degraded aerobically and anaerobically by the bacteria adhered to the roots and rhizomes of the plants with the porous medium [31]. The water treatment in a HF-CW with a HRT of 6 days and temperatures around 28°C is sufficient to obtain removals greater than 90%.…”

Constructed wetlands (CW) are efficient wastewater treatment technologies with low energy consumption. A constructed wetland with horizontal sub-surface flow was designed at a pilot scale involving Thalia geniculate as vegetation, with a wastewater loading rate of 204±66 L/day, using gravel as inert medium with a porosity and density of n= 56.3 ± 3.5 and 1666.7 ± 119.3 kg/m3, respectively. The reactor allows the biological treatment of 0.85 ± 0.05 and 0.66 ± 0.05 m3 of wastewater, with 4.2 days as a hydraulic retention time, favoring the removal of 85% of the average values of BOD with a k of-0.43 days-1. The pollutant analysis showed a pH value of 7.5 ± 0.1 in the reactor. The temperature (30.44 to 28.32°C), the electrical conductivity (4010 to 2922 μS/cm), the turbidity (144 to 17 UTN) and the bacterial biomass (30000 to 2646 mg/kg) decreased substantially from inlet to oulet across the reactor. The efficiency of the wastewater treatment in the CW is notable, nevertheless, keeping the appropiate hydraulic retention time is important in order to fully comply with the maximum permissible limits of 30 mg/L established in the Mexican environmental legislation (NOM-001-SEMARNAT-1996).

“…Likewise, various types of CWs may be combined in order to achieve higher removal efficiency. Such combinations of CWs are known as hybrid systems, which comprise most frequently VFS and HFS arranged in a staged manner [9,10].…”

Constructed wetlands (CWs) have increasingly been developed worldwide for stormwater and wastewater treatment. In this context, CWs have been seen as an economically attractive, energy-efficient way of providing high standards of wastewater treatment. In the present study, a CWS has specifically been designed and operated for domestic wastewater treatment. The removal efficiency of basic pollutants was evaluated in the CWs under free water surface (FWS) and horizontal subsurface flow conditions, employing two native species: Paspalum paniculatum and Thalia geniculata. The experimental results showed that the retention time throughout the treatments varied from 6.5 to 7.5 days; while temperatures of approximately 26°C were observed to reduce the load of pollutants. The experimental tests were highly effective for the wastewater treatment since the removal efficiencies of biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids, total nitrogen, and total phosphorus were found to be in the range of 79%-94%. The experimental data were statistically analyzed by the ANOVA approach and Tukey´s test. The treatments showed highly significant statistical differences (P<0.05). From the operating cost standpoint, the current native vegetation was proven to be satisfactory for wastewater treatment in tropical regions of Mexico.
