FAQs on 4040 Industrial RO Membrane
What is a 4040 fouling resistant membrane?
A 4040 fouling resistant membrane is built to resist scaling and biological buildup that clogs standard membranes over time. SpiroPure SP-FR4040 low fouling RO membranes uses a wider 34 mm feed spacer and high surface hydrophilicity to reduce fouling in demanding industrial wastewater applications.
What is the difference between FR4040 and a standard 4040 RO membrane?
The FR4040 uses a wider 34 mm feed spacer (versus 28 mm on standard membranes) and a more hydrophilic membrane surface, both of which reduce fouling from suspended solids and organic matter. This makes it better suited to dirtier feed water than standard brackish or low-pressure 4040 membranes.
What is the flow rate of the SpiroPure SP-FR4040 membrane?
The SpiroPure SP-FR4040 produces an average permeate output of 2,400 GPD (±15%) at 225 PSI, with a 15% fresh water recovery rate, tested against 2,000 ppm feedwater NaCl.
Where can the FR4040 fouling resistant membrane be used?
All Filters is one of a few companies offering low-fouling membranes for reverse osmosis. Choose SpiroPure's FR4040 for low fouling RO membrane applications treating chemical plant wastewater, surface water, mining wastewater, municipal reclaimed water, and other industrial wastewater sources prone to fouling.
Is the SP-FR4040 membrane NSF certified?
Yes. The SpiroPure SP-FR4040 is NSF 61 certified, confirming it meets recognized health-effects standards for materials in contact with drinking water, even though it's most commonly used in industrial wastewater and fouling-prone applications.
What is the price of the SpiroPure SP-FR4040 membrane?
The SpiroPure SP-FR4040 is priced to offer fouling-resistant performance at a lower cost than comparable brand-name elements. All Filters is one of a few companies offering low-fouling membranes for reverse osmosis. See this page for current SpiroPure pricing and available compatible model cross-references.
