Product Description

General Information

TFBW-8040 is manufactured as an equivalent for TM720-400 (TM720400) RO (reverse osmosis) membrane.

TFBW-8040 reverse osmosis membrane elements are developed for brackish water treatment, ideal for reverse osmosis plant managers and operators dealing with brackish water with pre-treatment.

This reverse osmosis membrane element provides consistency, high permeate water quality, high performance and productivity, and long service life.

Features & Advantages

• Provides high-quality permeate water
• 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 etc.

Specifications

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

Performance

Element Model	Membrane Active Area  ft^2 (m^2)	Feed Spacer  mil (mm)	Permeate Flow Rate^* GPD (m^3/d)	Stabilized Salt Rejection^**	Minimum Salt Rejection
TFBW-8040	400 (37.2)	28 (0.712)	10,500 (39.7)	99.6%	99.4%

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
