“…Umur lumpur yang terlalu rendah juga membuat pengolahan BOD tidak optimal, sehingga beban organik seperti BOD dan COD memiliki nilai yang tinggi pada outlet. Umur lumpur yang rendah berpotensi tidak melengkapi proses nitrifikasi, sehingga nilai amonia pada outlet masih tinggi (Dan et al, 2021). Nilai HRT selama 291 jam diduga karena debit aliran air limbah menuju ke bak aerasi yang pelan.…”

Instalasi Pengolahan Air Limbah Pelabuhan Perikanan Samudera Nizam Zachman Jakarta mengolah air limbah industri yang dihasilkan dari kegiatan industri pengolahan ikan. Seiring berjalannya waktu, perkembangan industri pengolahan ikan semakin meningkat sehingga menambah beban pencemaran air limbah. Bertambahnya usia pada komponen pengolahan limbah dan semakin bertambahnya beban pencemaran air limbah maka perlu dilakukan evaluasi untuk mengetahui efisiensi kinerja proses pengolahan air limbah. Evaluasi dilakukan pada beban pencemaran inlet dan outlet air limbah serta kinerja proses pada unit pengolahan air limbah. Pengukuran dan pengujian dilakukan untuk memperoleh data yang selanjutnya akan dilakukan analisis data. Hasil analisis akan dibandingkan dengan standar desain unit pengolahan dan hasil pengujian air limbah akan dibandingkan dengan baku mutu pengolahan ikan yang berlaku. Hasil uji inlet air limbah menunjukkan tingginya kandungan beban pencemaran organik yang dihasilkan oleh industri pengolahan ikan. Kemampuan Instalasi Pengolahan Limbah UPT PPS Nizam Zachman Jakarta menunjukkan nilai efisiensi penurunan beban pencemaran organik, yaitu X>80%. Nilai efisiensi penurunan beban pencemaran tersebut membuat parameter BOD, COD, TSS, Minyak dan Lemak tidak melebihi nilai baku mutu sehingga efisiensi penurunan beban pencemaran air limbah dinyatakan efektif, namun nilai efisiensi penurunan parameter amonia >80% masih melebihi nilai baku mutu, sehingga kinerja pengolahan air limbah dinyatakan tidak efektif dalam mengolah beban amonia pada air limbah. Wastewater Treatment Plant (WWTP) of Nizam Zachman Jakarta Fishing Port treats industrial wastewater produce from fish processing industry activities. Along the time, the development of the fish processing industry has increased that increasing the load of wastewater pollution. As the age of the waste treatment component increases and the load of wastewater pollution increases, it is necessary to evaluate the efficiency of the performance of the wastewater treatment process. Evaluation will be done on the influent and effluent pollution load of wastewater and process performance in the wastewater treatment unit. Measurement and examination conducted to obtain data for further data analysis. The results of the analysis will be compared with the WWTP design standards and the results of wastewater testing will be compared with the applicable fish processing quality standards. The results of the wastewater influent test show the high content of organic pollution loads produced by the fish processing industry. The penurunan efficiency of the wastewater treatment unit shows a very efficient level so that the results of the wastewater effluent test show a low pollution load value and are in accordance with the quality standard of Governor Regulation No. 69 of 2013 concerning Wastewater Quality Standards for Fish Processing Activities. Overall wastewater treatment performance shows a very efficient penurunan efficiency, however there are several activated sludge process parameters that are not in accordance with WWTP design standards and wastewater effluent parameters that exceed the quality standard values.

“…A shorter aeration time inhibits nitrification, resulting in accumulation of NH 4 + -N. 6 Conversely, prolonging the aeration time can not only ensure the tolerance of the system to a high concentration of aniline, but also provide more reaction time for the nitrification process lagging behind aniline degradation. 12 To summarize, a prolonged aeration mode can be used as a breakthrough for aniline degradation and simultaneous nitrogen removal, which provides a new idea for the treatment of aniline wastewater.…”

“…The aim is to achieve the highest possible quality of effluent of total nitrogen varying between 4 and 10 mg/L on a long-term average basis (Henze 1991). In addition, high efficiencies (90-97%) in removing organic compounds can be expected (Dan et al 2021). To identify the optimal distribution of aerated and nonaerated phases, several approaches to determine the required length of each phase for both ammoniacal nitrogen removal and nitrate removal in real-time can be used, as discussed in the following subsections.…”

The aim of the paper was to verify the possibility of using intermittent aeration to decrease outflow total nitrogen concentrations in municipal WWTPs of different capacities (15,780 PE, 23,000 PE, 806,250 PE). A simple time-based intermittent aeration control was used in the experimental work. The results of WWTPs are compared with each other and with literature sources. The use of intermittent aeration led to significant decrease of outflow total nitrogen concentration by up to 57% without the need of additional investment costs or the increase of operating costs. Nitrification kinetic tests and fluorescence in-situ hybridization observations proved that intermittent aeration has no negative impact on nitrifiers. The results proved that it is possible to utilize intermittent aeration for treatment plants initially designed with permanent aeration of nitrification sections if the current load is lower than the designed capacity. A necessary prerequisite for successful implementation of intermittent aeration is sufficient blower power. Although the time-based control is very simple and inexpensive to implement, the results are comparable to more complex systems such as systems based on rule-based systems for N-NH4+ and N-NO3− concentrations, on fuzzy logic or on mathematical models.
