General Information

TFFR-8040MFB is manufactured as an equivalent, replacement, alternative, retrofit, analogue to DuPont DOW FilmTec BW30FR-400/34 (BW30FR400/34) RO membrane.

DuPont DOW FilmTec BW30FR-400/34 equivalent reverse osmosis membrane elements TFFR-8040MFB are developed for brackish water treatment with high performance of fouling resistance, ideal for reverse osmosis plant managers and operators dealing with brackish water with normal pre-treatment.

These reverse osmosis membrane element provides consistency, high-quality filtrate, high performance and productivity, and long service life.

Features & Advantages

Improved feed spacer to thicker channel
Optimized design, good resistance to fouling
Greater restorability after chemical cleaning
Direct and economical element replacement

Applications

Industrial wastewater
Industrial process water
Reclaimed water recycling etc.

Specifications

Configuration: Spiral wound element
Membrane Polymer: Polyamide thin-film composite

Performance

Element Model	Membrane Active Area ft² (m²)	Feed Spacer mil (mm)	Permeate Flow Rate* GPD (m³/d)	Stabilized Salt Rejection**	Minimum Salt Rejection
TFFR-8040MFB	400 (37.2)	34 (0.864)	11,000 (41.6)	99.5%	99.3%

Standard test conditions:

The above performance is initial(data record after 30 minutes of operation), based on the following conditions:

2,000 ppm NaCl solution

225 psi (15.5 bar) operating pressure

25°C (77°F) operating temperature

15% permeate recovery

7.5-8 pH range

*Permeate flow for individual elements may vary but will be no more than ±15%.

**Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending on feed water characteristics and operating conditions.
