EconoPure - Water Extraction Core Technology
From Technology
The LFNano comes in several standard systems and multiples of these systems can be run in parallel to achieve larger capacities. The LFNano™ systems come in 20 centimeter (8 inch) diameter vessels currently with larger (and smaller diameters available on custom orders). The standard LFNano system come in odd numbers of pressure vessels from 3 to 11 and from 1 to 3 elements tall. The part number nomenclature is as follows:

What does that mean?
The current state of the art for reverse osmosis systems is based on a couple of central ideas:
- Since the membrane material itself is doing the work, roll elements as tightly as possible to maximize surface area
- No need to be concerned with exclusion selectivity, the RO will remove (almost) everything
- Make sure the membrane seen no suspended solids – Pretreat influent before the RO to the maximum extent possible so the RO sees only clear water
- Use high pressure to maximize recovery
EconoPure™ turns conventional wisdom upside down. Yes, the membrane material is doing the work, but a tightly packed element is subject to rapid fouling, has little tolerance for suspended solids, and requires an inordinate amount of energy to drive the osmotic. It also has low recovery.
The patented “Water Extraction” technique takes a better approach:
- OPEN the channels inside the element.
- Use the RIGHT membrane for the application. 65% of water treatment applications do not need RO. In most applications nanofiltration is sufficient
- Introduce a proprietary particulate in a highly controlled manner into the element so it provides a protective coating for the membrane
- Provide internal recirculation to abet a multi-pass system
- Eliminate multi-stage, expensive pretreatment
The result?
- A highly efficient, high recovery system
- Low pressure: lower capital costs, low energy consumption
- Simplified operation
- Low maintenance
- Long-life membrane elements
Water Extraction – it is at the core of everything we do.
