💧 DU WATER PURIFIERS — MEDIA REPLACEMENT & RO PRE-TREATMENT
Professional Media Replacement Service for RO Plants — using quality filtration media selected according to raw-water conditions and vessel size.
🔹 GRAVEL
Supports proper water distribution and drainage while preventing finer media from entering the outlet system.
🔹 SAND / SILICA SAND
Helps remove suspended particles, dirt, turbidity and other physical impurities from raw water.
🔹 ACTIVATED CARBON — Made in Taiwan
Reduces chlorine, unpleasant taste, odor and certain organic impurities, helping protect the RO membrane.
🔹 ARSENIC REMOVAL MEDIA — Exsense, Canada
Iron-Coated Granular Activated Alumina designed for arsenic reduction from water as part of the pre-treatment process.
⚙️ WHY MEDIA REPLACEMENT MATTERS?
Properly maintained pre-treatment improves RO performance, helps protect RO membranes and supports consistent water quality.
📌 Replacement Interval:
• General filtration media: approximately 1–1.5 years, depending on raw-water quality, flow rate and usage.
• Arsenic removal media: replacement is determined according to arsenic breakthrough, water testing and media capacity rather than simply a fixed time period.
📐 Different vessel sizes and media quantities are selected according to plant capacity, flow rate and raw-water conditions.
