Abstract

Laundry wastewater contains high levels of Chemical Oxygen Demand (COD) and phosphate (PO4), contributing to water pollution and eutrophication. This study investigates an integrated treatment approach using poly-aluminum chloride (PAC) coagulation and activated carbon adsorption to improve wastewater treatment efficiency. The research aims to determine the optimal PAC dosage (10% and 15%) and stirring time (0, 5, 15, 30, and 45 minutes) for maximizing COD and PO4 removal. A batch reactor system was used to conduct the treatment process, and the analysis followed the Indonesian National Standard (SNI) methods. The results demonstrated that the highest removal efficiencies were achieved with a 15% PAC dosage and a stirring time of 45 minutes. Under these conditions, COD levels were reduced from 2189.62 mg/L to 143.47 mg/L, achieving a 93% reduction. Similarly, PO4 levels decreased from 94.33 mg/L to 5.18 mg/L, corresponding to a 96% removal rate. These findings indicate that the combination of PAC coagulation and activated carbon adsorption is a highly effective treatment method for reducing pollution in laundry wastewater. This hybrid approach meets environmental discharge standards and presents a sustainable solution for large-scale wastewater treatment applications.

Abstract

The rapid expansion of the laundry industry, particularly in residential areas, has led to significant environmental challenges due to the discharge of untreated wastewater containing high levels of pollutants, such as Chemical Oxygen Demand (COD) and phosphate (PO4). This study aims to explore the effectiveness of anaerobic biofilter systems in reducing COD and PO4 levels in laundry wastewater. A lab-scale anaerobic biofilter reactor was designed and operated at varying hydraulic retention times (HRTs) of 9, 11, and 13 hours to treat the wastewater. The results showed that the anaerobic biofilter system effectively reduced PO4 levels, meeting Indonesian regulatory standards, with the highest removal efficiency observed at an HRT of 11 hours. However, while COD levels were reduced, they remained above the required quality standards, indicating the need for optimization of the treatment process. The study highlights the potential of anaerobic biofilters in laundry wastewater treatment and suggests further research into integrated treatment approaches for improved pollutant removal.

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%.
