Biological membrane filtration system for water treatment and a water treatment process

Biological membrane filtration enables modular wastewater treatment that keeps solids in-system while polishing effluent quality.

What it is

This system uses a membrane filtration module positioned to separate solids from an effluent stream after a porous biological filtration bed, retaining particles within the treatment train. The technical significance is the membrane’s ability to produce consistently higher effluent quality by physically removing suspended solids rather than relying only on settling. Before expiration, using the patented membrane-integration architecture could require licensing from the patent holder for commercial deployments.

What you could build

Launch packaged wastewater polishing units using the patented membrane filtration-in-biological-bed architecture for industrial sites and campuses.
