Stable salt rejection rate and high permeate flow rate
Optimized design, good resistance to fouling results in long service life
High chemical tolerance for cleaning with highly effective cleaning performance
Simple and economical element replacement

Applications

Industrial pure water
Industrial wastewater reuse
Slightly contaminated water

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
TFBW-8040-440A	440 (41)	28 (0.712)	11,500 (43.6)	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.

Element Dimensions

Length L inch (mm)	Diameter D inch (mm)	Permeate tube inner diameter d inch (mm)
40 (1,016)	7.9 (201)	1.125 (28.6)

Operating and Cleaning Limits

Maximum Operating Pressure	600 psi (41 bar)
Maximum Operating Temperature	45°C (113°F)
Maximum Chlorine Concentration	0.1 ppm
pH Range, Continuous	2-11
pH Range, Cleaning	1-13
Maximum Feed SDI (15 mins)	5
Maximum Element Pressure Drop	15 psi (1 bar)
Maximum Feed Flow	17 m³/h
