“…Contrary to this, the treatment of wastewater through constructed wetlands offers an ecologically sustainable, cost-effective, and natural system of wastewater treatment. Vertical subsurface flow constructed wetlands have been used primarily for the treatment of sewage wastewater (Zidan et al 2015) and are more efficient than the surface flow wetlands. Constructed wetland has evolved through the ages and its performance has been improved from time to time by conducting experiments.…”

Under the present investigation, vertical subsurface flow constructed wetlands (VSSFCWs) planted with macrophytes treated domestic sewage in an environmentally sustainable manner. Treatment of domestic sewage with wetlands is an alternative method that decreases energy consumption and economic costs involved in the treatment of environmental contaminants. This study evaluates the potential efficiency of VSSFCWs using two different macrophytes, Acorus calamus and Canna indica for the treatment of domestic sewage. To perform this study, two chambers of VSSFCWs of dimensions 2.48 m × 1.24 m × 1.54 m were built. The wetland was fed with the primary treated sewage at a hydraulic loading rate (HLR) of 0.67 m3/h (hours) in a batch flow. Treatment of primary sewage was observed from day 1 to day 6; once a day (i.e. 24 h to 144 h). The treatment of sewage was found to be significant up to day 6 (144 h); beyond this time, no significant removal was observed. The results revealed that both the wetland setups performed significant removal of TDS, BOD5, total nitrogen, and phosphate. The wetland planted with Canna indica was a better performer for the removal of TDS (22.31%), BOD5 (81.79%), total nitrogen (60.37%), and phosphate (80%).

“…It was observed that during the setup stage the porosity of coarse gravel, rubber, and plastic media was reduced by 19%, 12%, and 9%, respectively, compared to gravel and rubber media. Further, plastic media gave better performance because plastic media contain a biological enzyme promotor formula which helps in enhancing the bacteria growth (Shiwei et al 2019;Zidan et al 2015;Khateeb et al 2019). Pucher and Langergraber (2019) carried out the study at BOKU University, Vienna, about the various design parameters that affect the efficiency of VFCW by using hydrological modelling software (HYDRUS) wetland module for three VFCW with different substrate sizes (0.06-4 mm, 1-4 mm, and 4-8 mm), different organic loading, and different temperature.…”

Decentralized wastewater treatment has become inevitable as conventional wastewater treatment plants involve huge construction and maintenance costs. One of the most popularly used decentralized wastewater treatments is constructed wetlands. Constructed wetlands are a cost-effective and sustainable treatment method for domestic and industrial wastewater. Over the years, there has been a lot of improvement in the design and process approaches of constructed wetlands. This review paper aims to find the impacts of design processes like artificial aeration, design and flow pattern, effluent recirculation, substrate media, vegetation, and C/N ratio on the treatment performance of constructed wetlands. Based on the review, it is found that intermittent aeration along with recirculation, hybrid constructed wetlands and baffled constructed wetlands are an effective way to remove ammonia and organics from wastewater. Phosphorous removal in constructed wetlands is highly dependent on substrates rather than wetland plants. Further, the paper discusses the future scopes and challenges in terms of improving the efficiency of constructed wetlands, reuse of industrial waste as substrate, solar energy based aeration, etc., to make constructed wetlands a sustainable wastewater treatment technology.

“…Penerapan pengolahan limbah di kota Surabaya sebaiknya mengimplementasikan pengolahan dengan biaya rendah dan teknologi yang mudah dioperasionalkan dikarenakan mahalnya biaya operasional dan rumitnya sistem pengoperasian instalasi pengolahan air limbah (IPAL) 156 komunal. Untuk mencapai tujuan tersebut, sistem pengolahan air limbah dengan Sistem Lahan Basah Buatan (Constructed Wetlands) menjadi rekomendasi untuk pengolahan limbah yang ekologis karena karakteristik limbah domestik yang biodegradable (Vymazal, 2011;Zidan et al, 2015).…”

“…Meskipun nilai penyisihan BOD masih berada dibawah nilai penyisihan BOD pada masing-masing reaktor uji dengan tanaman. Kenaikan nilai penyisihan BOD pada reaktor kontrol terjadi karena adanya mikroorganisme dan alga yang tumbuh pada media kerikil dan berperan dalam mendegradasi polutan (Hidayah dan Aditya, 2010;Zidan, et al, 2015).…”

ABSTRAKPenanganan air limbah domestik Kota Surabaya selama ini dilakukan dengan 2 cara, yakni untuk blackwater dialirkan ke tangki septik dan greywater dialirkan ke drainase tanpa pengolahan. Hal ini menyebabkan peningkatan pencemar pada sungai sebagai air baku. Salah satu teknologi alternatif yang dapat diaplikasikan dengan mudah dan rendah biaya operasional dibanding pengolahan air limbah lainnya adalah constructed wetland dengan menggunakan tanaman Iris pseudoacorus sebagai kombinasi pengolahan biofilter dan proses fitoteknologi. Penelitian ini dilakukan untuk mengetahui efisiensi dari constructed wetland dengan tanaman Iris pseudoacorus untuk mengolah limbah domestik, serta menentukan bagaimana pengaruh dari adanya aerasi dan pengaruh waktu tinggal pada sistem constructed wetland dalam menurunkan bahan organik dan nitrogen pada air limbah. Penelitian ini dilakukan dalam skala uji laboratorium menggunakan reaktor berkapasitas 30 liter. Air limbah dialirkan pada reaktor dengan waktu tinggal 2 hari dan 3 hari, dengan variasi aerasi dan efisiensi pencemar diukur dengan parameter BOD, dan ammonia. Hasil penelitian ini menunjukan bahwa kemampuan penyisihan BOD, dan ammonia dari limbah air domestik oleh reaktor constructed wetland dengan tambahan aerasi dan waktu tinggal selama 4 hari sangat efektif. Reaktor ini mampu menurunkan nilai BOD hingga 96% dan nilai ammonia sebesar 97%.ABSTRACTWastewater domestic in Surabaya City has been treated in two methods, including septic tank for blackwater and directly discharged into drainage system for greywater. This caused an increasing pollutant loading in source water. Constructed wetland with Iris pseudoacorus, one of the alternative natural treatment technology through biofilter and phytotechnology process, could be applied easily and less costly to other treatment. This research was conducted to know the efficiency of constructed wetland with Iris pseudoacorus in domestic wastewater treatment, and to reveal the effect of aeration and detention time in reducing organic and nitrogen content in domestic wastewater. Experiment has been conducted on a laboratory scale of continue aerated reactor and without aeration as control reactor. Detention time (days) 2 and 3 was setup, then sample was taken for BOD and ammonia measurement. The results indicated that constructed wetland with aeration and detention time 4 days had a higher performance to remove BOD up to 96% and ammonia up to 97% than without aeration and less than 4 days process.Keywords: Domestic Wastewater, Constructed Wetland, Phytotechnology, Iris pseudoacorus, Aeration.Sitasi: Hidayah, E.
