Acid-resistance nanofiltration membrane elements can concentrate metals in acidic solutions such as sulfuric acid with no more than 20% concentration and phosphoric acid with no more than 30% concentration, which can also be used for acid solution purification. Such membrane elements can maintain high flux in a strong acid environment and operate stably for more than 12 months.

Acid Resistance NF Membrane
The NF membrane of the AR-S series (Acid Resistance) can concentrate 20% or less sulfuric acid and 30% or less phosphoric acid in the acid solution. It can also be used for the purification of acid solution. The membrane can maintain high flow and stable operation in a strong acid condition for more than 12 months.
Typical Acid Solution of Separation Membrane

20% H₂SO4
30% H₂PO4
4% HNO,
30% -40% Organic Acid

Storage Conditions of Separation Membrane

Before the first use, all membrane elements must be stored under the original packaging conditions.
The membrane is best placed in the original packaging and opened before the use of the water treatment system.
The transport temperature below 0°C may cause irreversible membrane damage and the transport temperature above 30°C may cause membrane degradation and deterioration of the protection solution.
Store in a cool, dry condition and a place that is not directly exposed to sunlight or artificial lighting. Storage temperature stays at 0°C to 30°C, and the longest storage time is 6 months.

General Information of Separation Membrane

Once wetted, the membrane element must always be wet.
The limited warranty we promised will expire due to the fact that the user does not strictly follow the operational restrictions and guidelines set forth in this Code.
If the system is in a shut-down state for a long time, the membrane element is advised to be placed in the protective solution to prevent the growth of microorganisms.
It is the user's responsibility if uses an incompatible chemical and lubricant, and causes undue influence on the original
The maximum allowable pressure drop of the single-pressure vessel is 60 psi (4.1 bar).
At no time can the backpressure be produced on the side of producing water to avoid the occurrence of harmful problems.
