GE PA Nanofiltration(NF) Membrane for Special Solution Separation and Concentration
The fields to which NF Membrane technique is suitable:
(1) Removal of divalent ion and organics by softening.
(2) Recovery of dyeing.
(3) Separation and refinement of oligosaccharide, concentration of high strong fruit juice.
(4) Separation of peptide and amino acid, concentration and purification of antibiotics.
(5) Concentration of milk and whey protein.
(6) Comprehensive utilization of agricultural products.
(7) Development of MBR.
* 4040 nano-filtration NF membrane adopted polyamide. It has moderate desalination rate and has relatively high desalination rate to remove macromolecule, multiple valence ion and especially noxious TOC substances in water, such as pesticide, weed-killer and THM predecessor.
* It is excellent in the water softening and organism removal. It is applicable to drinking water, municipal engineering and etc.

- Testing conditions: 500 ppm NaCl, 500 ppm MgSO4, 77F (25°C), pH 7-8, 15% recovery rate, testing after running for 30mins.
- The permeate flow error is 15%.
* 4040-SF nano-filtration element is specially developed for specific solute separation. It has relatively acute desalination performance than the normal one in a variety of applications, such as desalting organic compounds, acid processing, metal recovery from waste streams, and antifreeze recovery.
* According to the character of the solute and the require of the technology, we can provide different gridding, such as 28mil, 36mil and 40mil.

WHAT IS THE EXPECTED LIFE OF THE MEMBRANES?
Generally, the life of the membranes depends on the water quality but in normal cases or under standard parameters,
you can expect 1.5 to 2 years for domestic and approximately, 3 years for commercial and industrial elements.
HOW TO PROCURE YOUR MEMBRANE?
We have different channel partners and worldwide set up of our dealer network but we suggest you to contact our
direct representatives to guide you to the proper channel, to have you find your value procurement.
WHAT ARE THE DIFFERENT SIZES MANUFACTURED BY HI-TECH?
We manufacture every range of wet and dry membrane elements flow rate from 50-600 GPD for residential.
HOW IS RTL MEMBRANE DIFFERENT FROM OTHERS?
We offer value against your money, prices which are comparatively lower, performance equivalent to best
membranes available and with higher longevity.
