Abstract

Industri hidrogen peroksida meghasilkan limbah cair yang berpotensi mencemari lingkungan apabila tidak diolah dengan oprimal. Salah satu metode pengolahan yang umum diterapkan adalah koagulasi–flokulasi untuk menghilangkan partikel koloid dan kontaminan terlarut. Namun, penggunaan dosis koagulan dan flokulan yang tidak tepat dapat menyebabkan peningkatan pembentukan sludge, penurunan efisiensi pengolahan, serta meningkatnya biaya operasional akibat kebutuhan penanganan lumpur yang lebih besar. Oleh karena itu, dilakukan analisa penggunaan dosis optimal untuk menurunkan jumlah sludge tanpa mengurangi kualias effluent. Metode yang digunakan meliputi observasi langsung di industri, pengumpulan data, simulasi, dan analisis variasi dosis di laboratorium. Hasil analisis menunjukkan bahwa optimasi dosis koagulan dan flokulan mampu meningkatkan efisiensi proses pengolahan limbah dengan mengurangi pembentukan sludge serta mempertahankan kualitas effluent agar memenuhi baku mutu lingkungan.

The hydrogen peroxide industry generates wastewater that has the potential to cause environmental pollution if it is not treated properly. One of the most commonly applied treatment methods is the coagulation–flocculation process, which is used to remove colloidal particles and dissolved contaminants. However, the improper dosage of coagulants and flocculants can lead to increased sludge generation, reduced treatment efficiency, and higher operational costs due to greater sludge handling and disposal requirements. Therefore, this study was conducted to analyze the optimal dosage of coagulants and flocculants in order to reduce sludge generation without compromising effluent quality. The methods employed included direct observation at the industrial wastewater treatment plant, data collection, process simulation, and laboratory analysis of dosage variations. The results demonstrated that optimizing the coagulant and flocculant dosages improved the efficiency of the wastewater treatment process by reducing sludge generation while maintaining effluent quality in compliance with environmental discharge standards.
