Most groundwater lithium assets fall below the economic threshold of conventional Direct Lithium Extraction. At high throughput, M.L.E. makes 20 ppm groundwater viable — opening an asset class the industry has largely ignored.
20 ppm
Minimum economically viable concentration at high throughput — validated in Golan Heights, Israel
<200 ppm
Threshold below which conventional DLE becomes uneconomic — most groundwater assets fall here
Ambient
M.L.E. operates at ambient temperature — no heating or cooling required for standard groundwater feeds
High
Throughput volume compensates for low Li concentration — the key to groundwater economics
Groundwater lithium assets exist worldwide, from the Golan Heights to aquifers across the American Southwest and Central Asia. Many of these are well-characterized, accessible, and legally permitted. The problem is concentration: most sit below 200 ppm, outside the economic operating window of conventional DLE.
Conventional DLE products rely on high lithium concentration to generate sufficient output per unit of capital deployed. At 20–100 ppm, the math breaks down. The volume of water required to generate meaningful lithium output overwhelms the economics.
M.L.E. addresses this through a combination of high membrane throughput and low capital cost per processed volume. The Golan Heights, Israel project validated extraction at 20 ppm under real-world conditions, demonstrating that the asset class is viable at scale.
Viable recovery from 20 ppm lithium — validated in the field
The Golan Heights, Israel project extracted lithium meaningfully from 20 ppm groundwater at high throughput. This is a real-world data point, not a modeled projection.
No temperature requirements — operates at ambient conditions
Unlike geothermal, groundwater feeds are typically at ambient temperature. M.L.E. processes these without any heating or cooling step, keeping operating costs predictable.
Additive to existing water management operations
For municipal, agricultural, or industrial operators already managing groundwater, M.L.E. can be added to existing infrastructure as a revenue-generating step with no changes to primary operations.
Opens an undervalued asset class
Groundwater lithium rights are priced assuming conventional DLE constraints. Operations validated at 20 ppm fundamentally revalue the economics of assets previously considered marginal.
Reference Project
Golan Heights, Israel
20 ppm groundwater. High-throughput operation at ambient temperature. Validated meaningful lithium recovery under real-world conditions — the lowest concentration deployment in the DLE industry.
Relevant Operators
Water utilities and municipal operators, agricultural water managers, junior lithium explorers with low-concentration aquifer permits, and national water authorities in lithium-bearing regions.
Deployment Model
Modular skid installation on existing water infrastructure. No process changes upstream or downstream. Service priced per cubic meter processed.
The economics of conventional DLE are built around high-concentration feeds. Groundwater breaks the model at the concentration level alone — before any consideration of capital cost or throughput.
Concentration constraint
Conventional DLE products require approximately 200 ppm Li to be economic. Most groundwater assets sit at 20–100 ppm. At those concentrations, output per unit of capital falls below viability — the process cost exceeds the lithium revenue.
The M.L.E. solution
High membrane throughput at low cost per processed volume. Combined with lithium selectivity that works at low concentrations, this shifts the break-even point down to 20 ppm — validated operationally, not theoretically.
Operators who process lithium through M.L.E. can optionally integrate D.C.M. to convert purified lithium directly into battery-ready cathode material on-site, capturing additional margin across the supply chain.
