Abstract
ABSTRACTThe disposal of domestic and industrial waste to Surabaya river continues to increase, resulting in worse physical condition and severe pollution. The existence of Surabaya river is very important for the sustainability of the economy and the survival of society, industry, and commerce around the riverbank. In addition, Surabaya River becomes the raw water source of PDAM Surabaya and more than 3 million consumers of Surabaya PDAM depend on the water quality condition of Surabaya River. The purpose of this activity is to know the current condition of Surabaya River’s water quality and to determine the technology that can improve the water quality of PDAM. The conclusion that can be drawn from the water quality condition of Surabaya River is the high concentration of organic matter pollutants. Moreover, it is increasing in the dry season. With the increasingly poor quality of raw water coming from Surabaya river, consequently, the cost of processing will become more expensive. Therefore, conventional processing is not able to eliminate the pollutant compounds. One alternative technology to improve the quality of raw water is to apply a pretreatment process with the process biological by using biofilter technology. Keywords: water quality in Surabaya River, Surabaya Municipal Waterworks (PDAM), Biofilter technology ABSTRAKPembuangan limbah domestik dan industri di sepanjang Kali Surabaya terus meningkat, mengakibatkan kondisi fisik sungai semakin memburuk dan mengalami pencemaran semakin berat. Keberadaan kali Surabaya sangat penting bagi keberlangsungan perekonomian dan kelangsungan hidup bagi masyarakat, industri, dan niaga di sekitar bantaran kali. Selain itu Kali Surabaya menjadi sumber air baku PDAM Surabaya dan lebih dari tiga juta konsumen PDAM Surabaya bergantung pada kondisi kualitas air Kali Surabaya. Tujuan kegiatan ini adalah untuk mengetahui kondisi kualitas air Kali Surabaya dan menentukan teknologi yang dapat meningkatkan kualitas air baku PDAM. Kesimpulan yang dapat diambil dari kondisi kualitas air Kali Surabaya adalah tingginya konsentrasi polutan zat organik yang semakin meningkat pada musim kemarau. Dengan semakin buruknya kualitas air baku yang berasal dari Kali Surabaya, akibatnya biaya pengolahan akan menjadi semakin mahal dan pengolahan secara konvesional tidak mampu menghilangkan senyawa polutan tersebut Salah satu teknologi alternatif untuk meningkatkan kualitas air baku PDAM adalah dengan menerapkan proses pengolahan awal (pretreatment) dengan proses biologis menggunakan teknologi biofilter. Kata kunci: kualitas air Kali Surabaya, PDAM Surabaya, Teknologi Biofilter
