The complete, optimized design of the BioBarrier high-strength membrane bioreactor (HSMBR) system dramatically simplifies the settling, screening, direct aeration and ultrafiltration of the wastewater treatment process to remove 99.9% of contaminants. Installed in above- or below-grade locally sourced tanks, the BioBarrier MBR and HSMBR – from 500 to over 100,000 gal-per-day flows, also meet water recycling requirements.
