Product Description

Membrane Characteristics:
We use Composite nanofiltration membrane in a spiral wound configuration, with superior pH and temperature stability.

Operating Limits:
• Maximum operating pressure for NF6-8040 is 510 psi (35 bar).
Actual operating pressure is dependent upon system flux rate, as well as feed, recovery and temperature conditions.
• Permeate Pressure: Maximum allowed permeate pressure is 3 psi (0.2 bar).
• Differential Pressure: Maximum differential pressure limit is 10 psi (0.7 bar) per element.
Maximum differential pressure for any length vessel is 50 psi (3.5 bar).
• Temperature: Maximum operating temperature is 65°C.
• pH: Allowable range for continuous operation is 0-14.

When a stainless steel permeate tube is used, corrosive acids should be avoided.

Feed channel spacers: 31 mil and 46 mil 

Feed Flow Rate: Maximum and minimum flow rate are as follows:
2540 Minimum 2 gpm (7.5 liter/min) ; Maximum 5 gpm (19 liter/min)
4040 Minimum 6 gpm (22 liter/min) ; Maximum 17 gpm (65 liter/min)
8040 Minimum 25 gpm (95 liter/min); Maximum 75 gpm (285 liter/min)
Actual feed flow rate is dependent upon system flux rate, feed characteristics, fouling tendency and system design:

Lubricants: For element installation, use only water or glycerin to lubricate seals.
The use of petroleum or vegetable-based oils or solvents may damage the element and will void any warranty.
