[ Description ]
Dalam pengolahan limbah, senyawa nitrogen menjadi parameter tingkat pencemaran terhadap lingkungan. Limbah yang mengandung sejumlah besar senyawa nitrogen khususnya amonia tidak diizinkan dibuang ke lingkungan secara langsung karena akan berdampak buruk terhadap ekologi dan kesehatan manusia. Pengolahan limbah tersebut biasanya dilakukan secara konvensional dengan activated sludge. Namun teknologi ini memiliki beberapa kendala, khususnya pada proses sedimentasi yang membutuhkan waktu lama dan lahan yang luas. Tingginya kandungan amonia dalam limbah juga dapat menghambat kinerja mikroorganisme. Untuk mengatasinya, digunakan alternatif pengolahan limbah industri dengan Membrane Bioreactor (MBR) yang dikombinasikan dengan kondisi Anoxic. Penggunaan membran dapat menyisihkan bahan-bahan organik dan amonia dengan konsentrasi tinggi. Dalam penelitian ini digunakan lumpur aktif dari pengolahan limbah Surabaya Industrial Estate Rungkut (SIER) dan limbah sintetik sebagai influent MBR. Limbah pada MBR beroperasi pada volume 31,5 L. Variabel penelitian adalah konsentrasi COD 3600, 2800 dan 1800 mg/L serta SRT 5, 10 dan 20 hari pada COD 1800 mg/L. Hasil penelitian menunjukkan bahwa kinerja MBR secara keseluruhan relatif stabil dan baik. % removal COD tertinggi pada permeat diperoleh pada konsentrasi COD 1800 mg/L yaitu mencapai 90%. Jumlah N total permeat lebih kecil dari 0,5 jumlah N total influent atau % removal > 50 %, maka proses denitrifikasi dapat dikatakan berhasil. Untuk removal turbidity mencapai 98,47 hingga 98,85%. Pada MBR dari flux 30 L/m2.jam turun menjadi 15,6 L/m2.jam dalam waktu 25 menit, dibandingkan SMBR dari flux 27 L/m2 jam turun menjadi 5 L/m2.jam dalam waktu 5 menit.
Alt. Description
In industrial wastewater treatment, organic and nitrogen compounds become important parameters for determining the level of pollution to the environment. The wastewater which contains large amounts of organic and nitrogen compounds are not allowed to be wasted directly into the environment because it will adversely affect the ecology and human health. Wastewater treatment is usually done with a conventional activated sludge. But these technologies have several problems, especially on the sedimentation process takes time and a place widely. The high nitrogen content in the waste can also inhibit the performance of microorganisms. To overcome this problem, use of alternative industrial wastewater treatment Membrane Bioreactor (MBR) combined with anoxic tanks. Use of membrane can be set aside and the organic materials with high concentrations of nitrogen. From this research are expected to know the influence of various concentrations of biomass and COD load on the performance of the MBR to eliminate the organic materials and nitrogen in the anoxic condition. This study used activated sludge from wastewater treatment Surabaya Industrial Estate Rungkut (SIER) as an inoculant and waste \\\'synthetic\\\' as the MBR influent. Waste volume to the MBR operating at 31.5 L. Research variable is the concentration of COD 3600, 2800 and 1800 mg / L and SRT of 5, 10 and 20 days at 1800 mg COD / L. The results showed that the overall performance of the MBR is relatively stable and good. % COD removal obtained at the highest permeate COD concentration of 1800 mg / L, reaching 90%. Total number N in permeate is smaller than 0.5 the amount of total N in influent or % removal > 50%, then the process of denitrification can be said to be successful. For turbidity removal reached 98.47 up to 98.85%. The flux of MBR 30 L/m2.hours dropped to 15.6 L/m2.hours within 25 minutes, compared to the flux of SMBR 27 L/m2.hours down to 5 L/m2.hours within 5 minutes.
