Abstract

Stasiun Peralihan Antara Persampahan Kota Surabaya merupakan sarana pemindahan sampah dari alat angkut kecil ke alat angkut lebih besar. Pada Stasiun Peralihan Antara Persampahan ini dilakukan pengepresan sampah yang dimana akan menghasilkan air lindi (Leachate). Secara umum kondisi air lindi berwarna pekat, mengeluarkan bau yang tidak sedap, dan mencemari lingkungan. Air lindi (Leachate) umumnya mengandung beban pencemar seperti Chemical Oxygen Demand (COD) dan Total Suspended Solid (TSS) yang tinggi. Salah satu alternatif dalam mengolah lindi yaitu dengan menggunakan teknologi Moving Bed Biofilm Reactor (MBBR) bermedia Kaldness. Secara umum tujuan penelitian ini adalah mengetahui efisiensi penurunan beban pencemar limbah lindi menggunakan MBBR. Konsentrasi limbah lindi yang digunakan pada penelitian ini yaitu dengan perbandingan 80% lindi: 20% air (Reaktor A) dan 60% lindi: 40% air (Reaktor B). Desain reaktor MBBR yang digunakan yaitu skala laboratorium bervolume 0,012 m3 dengan debit rancangan 10 L/hari. Setelah dilakukan pengolahan dengan MBBR diperoleh nilai COD pada Reaktor A sebesar 73% dan Reaktor B sebesar 66%. Sedangkan nilai TSS pada Reaktor A sebesar 81% dan Reaktor B sebesar 92%.

Abstract

aboratory wastewater is produced through laboratory activities. Laboratory wastewater can have a large impact on the environment if it is not processed before being discharged into the water body. Laboratory waste treatment can be carried out using suspended growth technology to reduce pollutant loads, especially Biological Oxygen Demand (BOD5) and Chemical Oxygen Demand (COD). Aims: This study aims to treat wastewater produced by the activity of laboratory using suspended growth technology. Methodology and Results: This research was conducted by finding the most efficient rotor rotation in degrading the load of BOD5 and COD pollutants. The reactor used is a Mixed Flow Reactor type reactor made of acrylic material with a thickness of 5.5 mm. The reactor is arranged into three series with the same sampling time and different rotor turns that expressed in rotors per minute (rpm). The reactor series consists of Reactor I with 50 rpm rotor rotation speed, 100 rpm Reactor II and 150 rpm Reactor III. Processing is carried out using 8 hours of detention time and variation of sampling time every 8 hours. Conclusion, significant and impact study: From the results of the study obtained the highest level of effectiveness of reducing pollutant load on processing using 150 rpm rotor rotation and 40 hours sampling time which is 94.6% for BOD5 parameters and 94.4% for COD parameters.

Abstract

Untreated domestic wastewater can pollute the aquatic ecosystem. Vermifilter integrated with the Canna indica plant is one of the technological alternatives that can be used to treat domestic wastewater. One of affecting the performance of vermifilters is the vermibed media. Aim: This study aims to examine the effect of vermibed material on the concentration of COD, TP, DO, and the pH value of domestic wastewater treated with vermifilter combined with Canna indica plants. Methodology and Results: The research was conducted on a laboratory scale with a a continuous system using a plastic reactor dimension of 59 x 38 x 29 cm, which is filled with sand filter media, coconut fiber, gravel, and vermibed. The vermibed reactor consists of 4 reactors including reactor 1 (R1) vegetable vermibed, reactor 2 (R2) sawdust, reactor 3 (R3) banana peel, and reactor 4 (R4) cow dung. The results showed that  at the end of the research, the best performance is showed by reactor R2 that able to decrease COD 94.81%, TP 92.07%, DO increase 320.00%, pH 6.30±0.10.  Vermibed sawdust (R2) can lower COD, TP and raise DO higher to treat domestic wastewater by combining vermifilter with Canna indica plant.  Conclusion, significance, and impact study:  Vermifilter with Canna indica plant is an effective wastewater treatment in reducing COD, TP, increasing DO and pH value.   This treatment is easy processing of operation and maintenance, does not require large land, can be done on an individual scale, and is environmentally friendly.

Abstract

Household and commercial laundry businesses contribute to water pollution by generating liquid waste with high concentrations of Biological oxygen demand (BOD), Chemical oxygen demand (COD), surfactants, and phosphates. This study aims to analyze the effect of varying the height of a combined filtration medium comprising coconut fiber, zeolite, activated carbon, and gravel on the reduction of BOD and COD levels in laundry wastewater in Bratang Perintis Street, Wonokromo District, Surabaya City. Wastewater samples were collected in 30-liter volumes, with initial BOD and COD concentrations of 320 mg/L and 718 mg/L, respectively, exceeding the quality standards set by East Java Governor Regulation No. 72 of 2013. The wastewater was gravity-fed through four 4-inch-diameter acrylic reactors with media bed heights of 8, 10, 12, and 14 cm, each operated at a flow rate of 1 L/h with two treatment cycles. The results showed a maximum BOD reduction efficiency of 53.75% and a maximum COD reduction efficiency of 55.43% in the reactor with an 8 cm media height. Reactors with thicker media did not demonstrate higher efficiency, indicating the influence of hydraulic factors on system performance. The BOD and COD levels of the effluent from all reactors still exceeded quality standards, necessitating integration with advanced treatment processes to meet discharge standards for water bodies,

Abstract

Air sumur gali yang tidak memenuhi baku mutu memerlukan perlakuan agar memenuhi persyaratan estetika dan aman digunakan. Salah satu upaya untuk meningkatkan kualitas air sumur gali adalah dengan menggunakan teknologi adsorbsi bermedia karbon aktif, pertukaran ion dengan manganese greensand dan filtrasi bermedia pasir silika. Tujuan penelitian ini yaitu mengkaji efisiensi dan efektivitas penurunan kadar kesadahan, total padatan terlarut (TDS), Mangan (Mn), dan total coliform pada air sumur gali setelah diberikan perlakuan. Pengambilan sampel dilakukan selama kurun waktu 2 jam, setiap selang waktu 30 menit. Pengukuran parameter dilakukan pada kolom adsorbsi dengan ketinggian media pasir silica 8 cm, 13 cm, 17 cm untuk mengetahui setiap perubahan parameter yang diteliti. Hasil penelitian menunjukan bahwa efisiensi penurunan tertinggi terjadi pada filtrasi pada ketinggian media pasir silica 17 cm yakni: kesadahan 39,37%, TDS 58,58%, Mn 90,27%, dan total coliform 61.88%, sedangkan perlakuan efektif untuk penurunan parameter kesadahan, TDS, Mn namun kurang efektif untuk parameter total coliform.
