- Recovery of Single Element……………………. 15%
Performance of the Reverse Osmosis membrane 3013:
- Maximum production: 400 GPD at 25° C
- Maximum operating pressure: 300 psi – 2.07 MPa
- Maximum inlet temperature: 45° C
- Maximum loss of heat: 10 psi
- Maximum water turbidity: 1 NTU
- Maximum dirt density: 5 SDI- Chlorine tolerance: 0.1 ppm maximum
- Iron, manganese, maximum: 0.1 ppm
Dimensions:
- Length: 13 inches
- 3 inches diameter
The membranes should be stored wet and sealed in the original containers.
If the membrane is already wet, it should not dry out. Drying the membrane will cause irreversible changes.
The action of chlorine can damage the membranes.
In case of prolonged stoppage, it is recommended to immerse the membrane in a suitable protection solution to prevent biological growth.
When using or replacing the membrane for the first time, it is necessary to rinse for 0.5 to 1 hour. So keep it – discard the product.
The warranty is void for deposits fouled by deposits or biological growth, misused, poorly maintained, or stored.
