Product Overview
Overview
Saltworks offers a comprehensive suite of technologies focused on two main areas:
Water Treatment
Industrial wastewater treatment solutions
Brine concentration systems
Zero Liquid Discharge (ZLD) systems
Minimum Liquid Discharge (MLD) systems
Specific contaminant removal technologies
Lithium Processing
Concentrate, Refine, Convert (CRC) systems for post-Direct Lithium Extraction (DLE)
Pre and post-brine treatment for H2S removal, suspended solids, and temperature handling
Membrane concentration systems
Impurity removal technologies (calcium, magnesium, silica, hardness, boron)
Lithium carbonate (Li₂CO₃) conversion reactors
PROJECTS & PARTNERSHIPS
EMP Metals Corp. and Saltworks Technologies successfully completed a lithium conversion pilot using brine from EMP’s Direct Lithium Extraction (DLE) Field Pilot Facility in Saskatchewan.
The DLE process produced a concentrated eluate with over 2,000 mg/L of lithium, which Saltworks refined into battery-grade lithium carbonate (99.7% purity).
Business Model
Saltworks Technologies business model can have multiple engagement options including desktop reviews, technical consulting, pilot testing, full-scale plant delivery, and custom engineered solutions.
Technology Innovations
Lithium Processing
The technology platform incorporates several technical innovations that address specific challenges in lithium extraction and brine processing:
Level III modularity design that potentially reduces installation costs by up to 50% compared to conventional systems while minimizing startup time.
-
Membrane-Based Separation Technologies:
- BrineRefine: Chemical softening system for pretreatment
- XtremeUF: Ceramic ultrafiltration achieving 99.9% lithium purity
- XtremeRO: Reverse osmosis system capable of concentrating brines to 130,000 mg/L NaCl
- OARO (Osmotically Assisted Reverse Osmosis): Membrane technology achieving brine concentrations exceeding 200,000 mg/L TDS
- SelectNF: Nanofiltration for hardness removal with minimal chemical consumption
Single-step lithium carbonation process.
OARO consumes 8-12 kWh/m³ compared to 20-30 kWh/m³ for conventional evaporators.
