Company profile
researched Aug 2026Membrion is a Seattle-based industrial water technology company that develops Electro-Ceramic Desalination (ECD) systems for treating complex industrial wastewater. Its systems continuously separate dissolved salts and metals from wastewater streams, which the company contrasts with conventional filtration approaches that trap contaminants until performance degrades. The stated aim is to increase water recovery, support zero liquid discharge (ZLD) strategies, stabilize discharge performance and free up wastewater treatment capacity within existing treatment systems.
The company targets industries where wastewater complexity, regulatory pressure and reuse requirements strain conventional treatment. In semiconductor manufacturing, ECD is applied to stabilize wastewater streams as tool chemistries change and to recover critical minerals such as copper. In metal finishing, it is used to selectively remove dissolved metals from plating rinse water to maintain compliance, enable ZLD and support higher rinse rates and production growth. In food, beverage and consumer packaged goods facilities, it is used to remove dissolved salts that limit reuse and thereby increase water recovery. Published customer examples include a metal finishing facility that reached zero liquid discharge while reducing costs and a personal care manufacturer that increased water recovery and reduced discharge.
Membrion also publishes technical resources on topics including silica limits on reverse osmosis recovery, treatment of concentrated metal wastewater in semiconductor manufacturing, alternatives to evaporation ponds, and management of lithium-containing rinse water in EV-related manufacturing.
Business model
Membrion sells ECD-powered wastewater treatment solutions to industrial operators, engaging through evaluation, pilot programs (including its Cascade pilot system) and full-scale real-world deployments that integrate with a facility's existing treatment infrastructure rather than replacing it.
▸Full profile — market position, technology, go-to-market, geography
Market position
Membrion describes its customer base as including Fortune and Global 500 clients and characterizes itself as a heavily awarded water technology company.
Membrion positions ECD as functioning like a kidney rather than a coffee filter: instead of trapping contaminants until performance declines, the system continuously separates dissolved salts and metals, which the company says makes treatment performance adaptable in demanding wastewater conditions and allows deployment without replacing existing infrastructure.
Technology
Electro-Ceramic Desalination (ECD) uses ceramic-based membrane technology driven electrically to continuously separate dissolved salts and metals from wastewater streams, enabling selective metal removal, salt removal for reuse, and higher water recovery within existing treatment trains.
Go-to-market
The company works directly with industrial operators through evaluation, pilot programs such as its Cascade pilot system, and subsequent deployments, supported by industry-specific application content and case studies for semiconductor, metal finishing, and food, beverage and CPG segments.
Industrial facilities with complex wastewater and regulatory or reuse pressures, particularly semiconductor fabs, metal finishing and plating operations, and food, beverage and consumer packaged goods manufacturers.
Geography
Headquartered in Seattle, with customer and partner engagements described as spanning operators around the world.
