Differences Between Ultrafiltration Equipment and Ultrapure Water Equipment
Date: 2026-07-06 Categories: Industry News Views: 173
| Comparison Item | Ultrafiltration Equipment | Ultrapure Water Equipment |
| Filtration Precision | Only intercepts suspended solids, colloids and bacteria; unable to remove ions in water | Multi-stage filtration that removes all impurities including ions, organics, particles and bacteria |
| Core Membrane Components | Ultrafiltration membrane | Ultrafiltration membrane + Reverse Osmosis membrane + EDI / Polishing resin |
| Water Quality Indicators | Controls turbidity and SDI value; salinity remains unchanged | Controls resistivity, TOC and ion content; almost zero salinity |
| Outlet Water Quality | Purified clean water with abundant inorganic salts retained | High-purity deionized water |
| Main Functions | Raw water pretreatment, reclaimed water reuse, simple purified water production | Production of high-purity process water |
| Application Scenarios | Wastewater reuse, preliminary filtration of well water, pre-treatment for pure water systems | Laboratories, electronic chip manufacturing, pharmaceutical production, high-purity analysis, medical device cleaning |
| Equipment Complexity | Simple structure with few supporting accessories | Complete multi-stage process, complex equipment configuration |
| Operation & Maintenance Cost | Low-cost membrane elements, easy maintenance, low overall expenses | Expensive EDI and resin consumables, higher operation and maintenance costs |
