ESPA4-LD Equivalent

Equivalent, equivalence, replacement, alternative, analog, retrofit, analogue, derivative, substitution: Hydranautics ESPA4-LD, ESPA4LD

General Information

TFXLP-8040-34 is manufactured as an equivalent, replacement, alternative, retrofit, analogue to Hydranautics ESPA4-LD (ESPA4LD) RO membrane element.
Hydranautics ESPA4-LD equivalent reverse osmosis membrane elements TFXLP-8040-34 are developed for energy saving for water treatment in low TDS environments, ideal for the desalination of municipal water, groundwater with less than 1,000 ppm.
TFXLP-8040-34 reverse osmosis membrane element provides reliable performance and long service life at an extra low feed pressure, and can be widely used in pure water preparation and related industries.

Standard test conditions:
The above performance is initial (data record after 30 minutes of operation), based on the following conditions:
500 ppm NaCl solution
100 psi (7 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.
