Membrion

Membrion 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.
