Key Desalination & RO System Advantages
|
Superior Anti-Corrosion SS316L, Duplex 2205 & Super Duplex 2507 resist high-chloride pitting and crevice attack. |
High Hydraulic Efficiency CFD-optimized fluid channels deliver maximum pressure with minimal specific power consumption. |
Continuous 80+ Bar Duty Engineered for stable high-flux membrane separation in SWRO continuous operations. |
Engineered Structural Integrity for SWRO Membranes
| • | Heavy-Duty Wetted Alloys: Precision-machined 316L, Duplex, or Super Duplex components resist fluid erosion and pitting. |
| • | High-Pressure SiC Seals: SiC/SiC mechanical seals designed for continuous high-salinity marine duty. |
| • | Low-NPSH Hydraulics: Optimized impeller inlet geometry prevents cavitation under varying suction heads. |
| • | Compact Vertical Footprint: Space-saving inline configuration simplifies skid assembly and field maintenance. |
