3. Ultrafiltration Water Purifier Features and Benefits​.

​​6-Stage Filtration Process​

​

​​1. Stage 1: 316 Stainless Steel (SS) Filter Screen (40 Micron)​​

• ​​Material​​: 316L stainless steel (superior corrosion resistance, especially for saline/well water).
• ​​Function​​: Removes large sediment, sand, rust, and debris.
• ​​Key Benefit​​: ​​Self-cleaning & reusable​​ (backwashable design reduces maintenance).

​​2. Stage 2: PP Cotton Filter (5–20 Micron)​​

• ​​Material​​: Polypropylene (depth filtration).
• ​​Function​​: Captures finer particles, protecting downstream filters.
• ​​Key Benefit​​: ​​Low-cost replacement​​ (every 3–6 months).

​​3. Stage 3: Granular Activated Carbon (UDF)​​

• ​​Material​​: Granular Carbon.
• ​​Function​​: Adsorbs chlorine, pesticides, VOCs, and organic compounds.
• ​​Key Benefit​​: Adsorption of Most Impurities Heterochromatic Odor

​​4. Stage 4: Taste Activated Carbon (CTO)​​

• ​​Material​​: Coconut shell-based carbon.
• ​​Function​​: Secondary Adsorption of Chlorine, Volatile Organic Compounds I and Improved Taste.
• ​​Key Benefit​​: Adsorption Heterochromatic Odor and Improved Taste.

​​5. Stage 5: PVDF Ultrafiltration (UF) Membrane (0.01–0.1 Micron)​​

• ​​Material​​: Polyvinylidene fluoride (PVDF) — high chemical/thermal stability.
• ​​Function​​: Removes ​​bacteria, viruses, microplastics, and colloids​​.
• ​​Key Benefit​​: ​​No chemicals needed​​, retains beneficial minerals.

6. Stage 6: Post active carbon​

• ​​Material​​: Sintered Activated Carbon.
• ​​Function​​: Remove Peculiar Smell in Water and Supplement a Small Number of Mineral Elements..
• ​​Key Benefit​​: ​​Final safety barrier​​ :Second Improvement of Taste and Odor Removal.

Applications​​
