The BioBarrier MBR system from Bio-Microbics is designed to simplify the settling, screening, direct aeration and ultrafiltration of the wastewater treatment process to remove 99.9 percent of contaminants. Certified to NSF/ANSI 40 Class I, NSF/ANSI 245 (nitrogen reduction) and NSF/ANSI 350 standards, this black water/graywater treatment system establishes the material, design, construction and performance requirements for onsite residential and commercial applications. Installed below or above grade, it offers flows from 500 to more than 27,000 gpd, and meets water quality requirements for the reduction of chemical and microbiological contaminants for nonpotable water use. Treated wastewater can be used for restricted indoor water use and/or unrestricted outdoor water use. 800/753-3278; www.biomicrobics.com.
