Nutrient removal by Phragmites australis (Cav.) Trin. ex Steud. In the constructed wetland system

The paper presented results of the comparative assessment of nutrient absorption capacity by plants, including reed grass (Phragmites australis L.) and vetiver (Vetiveria zizanioides L.). The constructed wetland models were designed with experiments (i) - Loading 1 (T1): reed grass (S1), vetiver (V1) + control (C1); (ii) - Loading 2 (T2): reed grass (S2), vetiver (V2) + control (C2); (iii) - Load 3 (T3): reed grass (S3), vetiver (V3) + control (C3). The study investigated the surface water quality parameters including nutrients such as TKN (Total Kieldalh Nitrogen), ammonium (NH4-N), nitrite (NO2-N), nitrate (NO3-N), total phosphorus (TP) and phosphate (PO43-). Results showed that there was significantly decreasing change related to pollutant concentration in the tanks. The studied results showed that the water treatment efficiency of Loading 1 (T1) possessed highly nutrient absorption capacities such as nitrogen and phosphorus. Comparing the nitrogen and phosphorus removal efficiency, there was no statistically significant difference between reed grass and vetiver in the same loading (P>0.05). In general, in the same loading levels, the plants’ nutrient removal efficiencies were often higher than the control experiments (P<0.05). The effluent findings illustrated some parameters of water quality that met to National Technical Regulation of surface water quality for agricultural irrigation purposes (QCVN 08-MT:2015/BTNMT). Therefore, the constructed wetland technology obtained highly effective characteristics and supplying the environmental friendly advantages.

Wetland System

Penelitian ini bertujuan mengkaji efisiensi jenis tanaman dan waktu tinggal dalam menurunkan kandungan amoniak pada air limbah domestik menggunakan Bio-Rack Wetland. Bio-rack merupakan sistem baru dalam media pengolahan constructed wetland. Bio-rack wetland dijalankan dengan variasi waktu tinggal selama 15 jam dan 20 jam. Media bio-rack terbuat dari pipa PVC dengan ukuran diameter 22 mm. Tumbuhan yang ditanam pada media bio-rack adalah Typha latifolia dan Phragmites australis. Efisiensi penyisihan suhu, pH, dan amoniak pada reaktor bio-rack wetland dilakukan berdasarkan prosedur laboratorium. Efisiensi sistem bio-rack wetland yang terbaik dalam menyisihkan pencemar amoniak yaitu tanaman Typha latifolia dengan efisiensi penyisihan sebesar 35,2% pada waktu tinggal 20 jam. Sedangkan pada tanaman Phragmites australis mampu menyisihkan kadar amoniak sebesar 28,4% dengan waktu tinggal 20 jam. Efisiensi penyisihan parameter uji terbukti lebih baik pada bio-rack wetland dengan tanaman Typha latifolia pada waktu tinggal 20 jam. Kata Kunci: Amoniak, Bio-rack Wetland, Phragmites australis, Typha latifolia, Waktu Tinggal. This study aims to assess the efficiency of plant species and residence time in reducing ammonia content in domestic wastewater using Bio-Rack Wetland. Bio-rack is a new system in the constructed wetland processing media. Wetland bio-rack is run with a variation of the residence time of 15 hours and 20 hours. Bio-rack media is made of PVC pipes with a diameter of 22 mm. Plants grown on bio-rack media are Typha latifolia and Phragmites australis. The removal efficiency of temperature, pH, and ammonia in the wetland bio-rack reactor is carried out based on laboratory procedures. The best efficiency of the bio-rack wetland system in removing ammonia pollutants is Typha latifolia plants with a removal efficiency of 35.2% at a residence time of 20 hours. Whereas the Phragmites australis plant can set aside ammonia levels of 28.4% with a residence time of 20 hours. The removal efficiency of the test parameters was proven to be better in the wetland bio-rack with Typha latifolia plants at a residence time of 20 hours. Keywords: Ammonia, Bio-rack Wetland, Phragmites australis, Typha latifolia, the length of time.
