Reverse Osmosis Membrane Filter

Characteristics of RO Membrane

		R/O Membrane Filter eliminates all pollutants such as heavy metals, virus, bacteria and organic chemicals through stomata with the size of 0.0001 μm , which is 1/1,000,000 of the thickness of human hair.
		R/O Membrane separates organic chemicals better than inorganic chemicals and electrolytes better than non-electrolytes. R/O Membrane can eliminate not only the substances of particle nature but also the substances of ionic nature, the particle size of which is very small.
		R/O Membrane separates substances without changing the phase of the substances and is applicable to various fields as it has good physical and chemical durability.

Superior Rejection Rate of R/O Membrane (Rejection, %)

Substances	Rejection Rate (%)
Ions	99+
Nitrates	95
Organics	95
THM	99+
Silica	98+
Bacteria and Particles	100%
Dissolved gases	Unable to eliminate

Effect of recovery

As shown in Figure 1, reverse osmosis occurs when the natural osmotic flow between a dilute solution and a concentrated solution is reversed through application of feedwater pressure. If percentage recovery is increased (and feedwater pressure remains constant),the salts in the residual feed become more concentrated and the natural osmotic pressure will increase until it is as high as the applied feed pressure.
This can negate the driving effect of feed pressure slowing or halting the reverse osmosis process and causing permeate flux and salt rejection to decrease and even stop.





Features

HYUNDAI R/O reverse osmosis ( RO) membrane elements for home drinking water are the industry? most reliable. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers and residential customers can rely on. HYUNDAI R/O elements are shipped dry for convenient handling and long shelf-life. These elements are NSF/ANSI Standard 58 listed.
HYUNDAI R/O home drinking water elements are rated a 50 psi and will purify about 20 % more water than competitive elements rated at 60 psi (please see reference charts on page two for more information)

Advantage

1. The membrane element is supplied in dry condition to have more shelf life (12 month)
2. The thin film of membrane sheet was made by DOW FILMTEC USA
3. The life of elements is much stable and longer
4. The membrane is manufactured by full automatic machine to keep quality assurance.

1. Permeate flow and salt rejection based on the following test conditions : 250ppm (NaCl) softened tap water, 77°F(25°C), 15% recovery and the specified applied pressure.
2. Permeate flows for individual elements may vary +/-20%.
3. For the purpose of improvement, specifications may be updated periodically.

General information

		The first full tank of permeate should be discarded. Do not use this initial permeate for drinking water or food preparation.
		Keep elements moist at all times after initial wetting.
		If operation limits and guidelines given in this bulletin are not strictly followed, the limited warranty will be null and void.
		To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution.
		The membrane shows some resistance to short-term attack by chlorine ( hypochlorite) Continuous exposure, however, may damage the membrane and should be avoided.
		The customer is fully responsible for the effects of incompatible chemicals and lubricants on elements. Their use will void the element limited warranty.
