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.

In recent centuries, issues such as efficient use of water resources, water quality and water supply have become important for many countries. Countries have focused on developing strategies that can protect water and using water in the most efficient way including treatment of wastewater. In addition, it has become important to provide sustainability of the natural treatment systems instead of complex and expensive wastewater treatment facilities that are rapidly developing. On the other hand, the researches on natural treatment of wastewater are still inadequate. Therefore, the feasibility and performance of new stragtegies about natural treatment systems should be developed and evaluated. For this purpose, a pilot facility was developed which utilizes a natural soil-column with different gradations in order to provide the treatment of domestic wastewater. In this way, not only the wastewater treatment performances of different soils but also some engineering properties of soils affected by wastewater filtration were examined. As a result of this research, it was found that soil filtration can be effective in the treatment of wastewater subjected to pre-sedimentation and can be affected by the pollutant load of the filtration environment.
