Abstract

Proses aerasi merupakan salah satu tahapan penting dalam pengolahan air baku di PDAM Surya Sembada Surabaya untuk meningkatkan kadar oksigen terlarut (Dissolved Oxygen/DO) serta mendukung proses oksidasi senyawa besi dan mangan. Efisiensi proses ini dipengaruhi oleh jumlah dan jarak pemasangan aerator sehingga diperlukan evaluasi untuk memperoleh konfigurasi yang optimal. Penelitian ini bertujuan menganalisis kinerja sistem aerasi, mengevaluasi pengaruh jumlah dan jarak aerator terhadap efisiensi aerasi, serta menentukan konfigurasi yang memberikan peningkatan DO secara optimal dengan konsumsi energi yang efisien. Metode yang digunakan adalah pengukuran kadar DO pada beberapa titik sepanjang kanal aerasi dengan variasi jumlah aerator dan analisis distribusi DO berdasarkan jarak dari aerator. Hasil penelitian menunjukkan bahwa konfigurasi 2–3 unit aerator menghasilkan peningkatan DO yang relatif merata hingga mencapai 2,03–2,10 mg/L. Penambahan aerator lebih dari tiga unit tidak meningkatkan efisiensi secara signifikan, melainkan menyebabkan over-aeration pada area tertentu sehingga distribusi oksigen menjadi tidak merata. Jarak antar aerator yang paling efektif berada pada kisaran 60–70 meter, dengan peningkatan DO maksimum sebesar 110,39% pada jarak sekitar 66 meter sebelum kembali menurun akibat konsumsi oksigen dan pelepasan ke atmosfer. Dengan mempertimbangkan peningkatan DO, pemerataan distribusi oksigen, dan efisiensi energi, konfigurasi 2–3 unit aerator dengan jarak antar aerator 60–70 meter direkomendasikan sebagai kondisi operasi yang paling optimal pada kanal PDAM Surya Sembada Surabaya.

The aeration process is one of the essential stages in raw water treatment at PDAM Surya Sembada Surabaya, aimed at increasing Dissolved Oxygen (DO) levels and supporting the oxidation of iron and manganese compounds. The efficiency of this process is influenced by the number of aerators and the spacing between them; therefore, an evaluation is required to determine the optimal configuration. This study aims to analyze the performance of the aeration system, evaluate the effects of the number and spacing of aerators on aeration efficiency, and determine the configuration that provides optimal DO enhancement with efficient energy consumption. The research method involved measuring DO concentrations at several points along the aeration channel under different aerator configurations and analyzing the DO distribution based on the distance from each aerator. The results showed that a configuration of 2–3 aerators produced a relatively uniform increase in DO, reaching 2.03–2.10 mg/L. Increasing the number of aerators beyond three did not significantly improve aeration efficiency; instead, it caused over-aeration in certain areas, resulting in an uneven oxygen distribution. The most effective spacing between aerators was found to be 60–70 m, with the maximum DO increase of 110.39% occurring at a distance of approximately 66 m, after which the DO concentration gradually decreased due to oxygen consumption and atmospheric release. Considering the DO improvement, oxygen distribution uniformity, and energy efficiency, a configuration of 2–3 aerators with an inter-aerator spacing of 60–70 m is recommended as the optimal operating condition for the aeration channel at PDAM Surya Sembada Surabaya.
