Abstract

Beban limbah cair industri kertas meningkat seiring dengan peningkatan produksi kertas di Indonesia. Konsentrasi COD berkisar antara 8.300–45.384 mg/L O2 dan TSS sebesar 41.000 mg/L. Salah satu upaya untuk mengurangi beban COD dan TSS di dalam limbah cair industri kertas adalah dengan memanfaatkan proses lumpur aktif. Penelitian ini difokuskan pada pengaruh proses sedimentasi di dalam unit lumpur aktif untuk mereduksi COD dan TSS. Penelitian ini juga mencakup analisis dua tipe pengendapan, yaitu pengendapan partikel diskrit dan pengendapan flok. Tujuan utama penelitian ini untuk mengestimasi nilai hydraulic loading rate dan solid loading rate serta rekomendasi dimensi unit sedimentasi lumpur aktif. Penelitian ini meliputi kegiatan monitoring kinerja proses dengan tiga variasi waktu detensi (HRT). Beberapa variabel yang diperhatikan untuk mencapai tujuan penelitian ini, antara lain kecepatan pengendapan bebas (v), percepatan gravitasi (g), massa jenis partikel (ρs), massa jenis fluida (ρ), diameter partikel (d), dan koefisien penarikan atau drag coefficient (Cd). Pengukuran reduksi COD mengacu pada SNI 6989.2:2009 dan pengukuran reduksi TS mengacu pada SNI 06-6989.26-2005. Penelitian ini menunjukkan bahwa kecepatan pengendapan discrete particle settling tergantung pada karakteristik satuan partikel berdasarkan diameter partikel. Kecepatan pengendapan flocculant settling tergantung pada pengaruh interaksi partikel dalam pembentukan flok atau gumpalan beberapa entitas partikel. Jika ditinjau dari nilai umur lumpur (SLR), HRT 8 jam dan HRT 12 jam menunjukkan kondisi under loaded pada unit sedimentasi. Sementara itu, nilai HLR dan SLR pada HRT 6 jam telah memenuhi rentang kriteria desain lumpur aktif. Dengan demikian, desain terbaik untuk unit sedimentasi sekunder lumpur aktif, yaitu HRT 6 jam dengan HLR sebesar 42,16 m3/m2hari, SLR sebesar 102,45 kg/m2hari dan rata-rata reduksi padatan total mencapai 89,26%.ABSTRACTThe influence of paper production affect simultenously to the increase of pulp and paper wastewater in Indonesia. The COD concentration ranged from 8,300–45,384 mg/L O2 and TSS was 41,000 mg/L. Reducing COD and TSS concentrations in the paper industry wastewater is to utilize by using activated sludge processes. This research was focused on the effect of sedimentation process in activated sludge to reduce COD and TSS. This research also included the analysis of two types of deposition, namely discrete particle settling and floc settling. Main objective this research was directed at determining the value of the hydraulic loading rate and solid loading rate as well as recommendations for the dimensions of the activated sludge sedimentation unit. This research included monitoring of process performance with three variations of detention time (HRT). There were several variables that are considered to achieve the objectives of this study, including free deposition velocity (v), acceleration due to gravity (g), particle density (ρs), fluid density (ρ), particle diameter (d), and drag coefficient. coefficient (Cd). The COD and TS reduction measurement refered to SNI 6989.2:2009 and SNI 06-6989.26-2005, respectively. This study showed that the speed of discrete particle settling depends on the characteristics of the particle unit as seen from the particle diameter. The deposition rate of flocculant settling depends on the effect of particle interactions in the formation of flocs or agglomerates of several particle entities. When viewed from the SLR value obtained, the 8-hour HRT and 12-hour HRT indicated that the sedimentation unit was in an under-loaded condition. Meanwhile, the HLR and SLR values at HRT 6 hours complied the activated sludge design criteria. Thus, the best design for the activated sludge secondary sedimentation unit was HRT 6 hours with an HLR of 42,16 m3/m2day, an SLR of 102,45 kg/m2day and an average total solids reduction of 89,26%.

Abstract

This paper proposes a method for controlling groundwater level in order to maintain a certain desired height by using a simple fuzzy control system. The control signal is determined by evaluating the state of water surface height deviatioh from the desired height on a 4 quadrant phase plane. The control signal is then used to determine the number of drainage or irrigation pumps, which must be operated. Simulation using actual datafrom the jield shows that the proposed method is very effective to maintain the desired height of water surface. This method is very simple, therefore it can be easily implemented using a personal computer or a microcontrol/er, or up-loaded to a P LC (Programmable Logic Controller).
