Description
Dow Filmtec BW30FR-400/34i Antifouling Reverse Osmosis Membrane Element
Although their core parameters are similar, the BW30FR-400/34i is an improved and upgraded version of the BW30FR-400/34. The main differences are as follows:
|
Feature
|
BW30FR-400/34
|
BW30FR-400/34i
|
|---|---|---|
|
Product Positioning
|
Standard antifouling reverse osmosis membrane
|
New-generation enhanced antifouling membrane (The “i” typically stands for improved/optimized)
|
|
Antifouling Performance
|
Excellent
|
Superior (Further optimized for high biofouling and high organic content water)
|
|
Cleaning Tolerance
|
High
|
Higher (Wider pH range for chemical cleaning, higher recovery efficiency)
|
|
Feed Spacer Design
|
34mil standard antifouling feed spacer
|
34mil optimized feed spacer with enhanced anti-clogging capability
|
|
Flux Stability
|
High
|
Higher and more stable, with lower long-term flux decline
|
|
Suitable Water Quality
|
High-fouling, high-SDI surface water, wastewater reuse, etc.
|
Severely fouling water, high COD/BOD wastewater, seawater desalination pretreatment, etc.
|
In simple terms:
The BW30FR-400/34i is a performance-enhanced version of the BW30FR-400/34, with further optimization in antifouling capability, cleaning efficiency, and long-term stability, making it suitable for more complex and higher-fouling water conditions. Selection should be based on actual water quality fouling levels and operational maintenance requirements.
