Purified Water (PW) merupakan bahan baku utama dalam produksi Water for Injection (WFI) dan pure steam. Sebagai bahan baku kritis, PW harus memenuhi standar Farmakope Indonesia dan USP, terutama untuk parameter konduktivitas, Total Organic Carbon (TOC), dan Total Plate Count (TPC). PW dihasilkan dari pemurnian air tanah menggunakan teknologi Electrodeionization (EDI) dengan konfigurasi single EDI dan double EDI. Penelitian ini bertujuan membandingkan efektivitas kedua sistem EDI di PT Satoria Aneka Industri, yaitu Plant 2 (double EDI) dan Plant 3 (single EDI), berdasarkan parameter konduktivitas, TOC, dan TPC. Pengamatan dilakukan selama November–Desember 2024 melalui pemantauan harian dan uji laboratorium. Hasil menunjukkan bahwa Plant 2 memiliki efisiensi penurunan konduktivitas yang lebih stabil (80,65%–92,54%) dibandingkan Plant 3 (65,00%–93,37%), serta seluruh hasilnya memenuhi standar USP. Nilai TOC kedua sistem relatif sama (104 dan 103 ppb), menunjukkan jumlah unit EDI tidak berpengaruh signifikan terhadap kadar karbon organik. Namun, TPC Plant 2 lebih rendah (4,5 CFU/100 mL) dibandingkan Plant 3 (14,25 CFU/100 mL), yang menunjukkan keunggulan mikrobiologis sistem double EDI. Oleh karena itu, konfigurasi double EDI lebih direkomendasikan untuk menghasilkan mutu Purified Water yang konsisten.
