Abstract
Peningkatan kebutuhan air bersih oleh tenant di kawasan industri serta keterbatasan sumber air alami mendorong PT Surabaya Industrial Estate Rungkut (SIER) untuk mengolah kembali air effluent instalasi pengolahan air limbah (IPAL) melalui teknologi ultrafiltrasi dan reverse osmosis yang didukung penggunaan cartridge filter. Namun, tingginya frekuensi penggantian cartridge setiap 2-3 hari akibat belum optimalnya proses pre-treatment menyebabkan peningkatan biaya operasional. Studi ini bertujuan merancang perencanaan optimasi proses untuk memperpanjang umur cartridge serta mengefisienkan sistem pengolahan. Strategi perencanaan mencakup peningkatan efisiensi pre-treatment melalui reduksi kontaminan (Fe, Mn, Al, dan minyak lemak), penyesuaian dosis koagulan dan flokulan, penggunaan agitator, serta penjadwalan maintenance berbasis kondisi aktual. Estimasi hasil menunjukkan penurunan TSS > 91%, Fe mencapai 0–10,7 mg/L, Mn mencapai 1,6–6,1 mg/L, Al mencapai 1,0–6,9 mg/L, dan minyak lemak turun menjadi 0,18–0,89 mg/L. Dengan penurunan ini, umur cartridge diperkirakan meningkat menjadi 5–7 hari. Perencanaan ini mendukung efisiensi operasional jangka panjang, meningkatkan kepatuhan terhadap regulasi mutu air dan K3, serta mencerminkan penerapan profesionalisme dan etika keinsinyuran dalam menyelesaikan permasalahan dan mengoperasikan industri pengolahan air secara sistematis dan berkelanjutan.

The increasing demand for clean water by tenants in the industrial estate as well as limited natural water sources prompted PT Surabaya Industrial Estate Rungkut (SIER) to recycle wastewater treatment plant effluent water through ultrafiltration and reverse osmosis technology supported by the use of cartridge filters. However, the high frequency of cartridge replacement every 2-3 days due to the non-optimized pre-treatment process causes an increase in operational costs. This study aims to design a process optimization plan to extend cartridge life and streamline the treatment system. The planning strategy includes improving pre-treatment efficiency through contaminant reduction (Fe, Mn, Al, and oil and grease), adjusting coagulant and flocculant dosage, using agitators, and scheduling maintenance based on actual conditions. Estimated results showed a reduction in TSS > 91%, Fe reached 0-10,7 mg/L, Mn reached 1,6-6,1 mg/L, Al reached 1,0-6,9 mg/L, and oil and grease dropped to 0,18-0,89 mg/L. With these reductions, cartridge life is expected to increase to 5-7 days. This planning supports long-term operational efficiency, improves compliance with water quality and OHS regulations, and reflects the application of professionalism and engineering ethics in solving problems and operating the water treatment industry systematically and sustainably.
