General Information

TFFR-8040L is manufactured as an equivalent, replacement, alternative, retrofit, analogue to Lanxess Lewabrane RO B400 FR RO membrane element.

TFFR-8040L reverse osmosis membrane elements 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.

Lanxess Lewabrane RO B400 FR equivalent 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
Economical equivalent element for direct replacement to Lanxess Lewabrane RO B400 FR

Applications

Municipal sewage
Industrial wastewater
Industrial process water
Reclaimed water recycling etc.

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.
