JUNTAI EPDM Aeration Membranes: Advanced Anti-Clogging & Durability for Wastewater Systems
In the demanding environment of wastewater air diffuser operations, JUNTAI's EPDM membranes redefine reliability through groundbreaking material science and precision engineering.
1. Revolutionary Anti-Clogging Performance
Traditional EPDM diffuser membranes fail due to chemical interactions:
-Zinc salts in standard formulas react with Ca²+/Mg²+ ions → inorganic scaling
-Hydrophilic additives attract organic fouling in aeration diffusers wastewater
JUNTAI's Solution:
✔️ Zinc-Free Formula: Eliminates hydrophilic scaling agents
✔️ Anoleylamine Surfactant Tech:
-Creates hydrophobic pore surfaces (contact angle >110°)
-Reduces biofilm adhesion by 60% vs conventional coarse bubble disc diffuser membranes
✔️ Oil-Resistant Compound: Withstands FOG concentrations up to 150 mg/L
Proven Results in Municipal WWTPs:
-18-month continuous operation without chemical cleaning
-Maintains 92% initial OTE vs 67% for standard diffusers in water treatment plants
2. Ultra-Durable Bimodal Molecular Architecture
JUNTAI's patented EPDM 8600N (ExxonMobil) features:
- Dual-Peak Molecular Weight Distribution:
High MW chains (≥400k g/mol): Tear resistance >28 N/mm
Low MW chains (≤150k g/mol): 300% elongation at break
- Branch-Controlled Polymerization: Prevents stress cracking in industrial wastewater diffusers
Pore Density Innovation:
| Parameter | JUNTAI Membrane | Conventional EPDM |
|---|---|---|
| Pores/cm² | 28-32 | ≤20 |
| Pore Diameter | 0.8-1.2mm | 1.5-2.0mm |
| Airflow Resistance | 2.1 kPa/m | 2.8 kPa/m |
Operational Benefits:
✅ 30% finer bubbles for enhanced fine bubble diffusers wastewater treatment
✅ 20% lower blower energy consumption
✅ 5-year warranty against tearing (ASTM D624 tested)
