BioBarrier MBR (500 to 3,000 gpd) and HSMBR (1,500 to 18,000 gpd) systems from Bio-Microbics are easy to install, operate and maintain. The membranes and processes act as a physical barrier for nearly all common wastewater pollutants. Approved for water reuse (NSF/ANSI Std 350), the pre-engineered modular systems ship installation-ready to fit into new or existing tanks. They meet state regulatory requirements and produce effluent with BOD less than 2 mg/L, TSS less than 2 mg/L and ammonia less than 1 mg/L. They effectively remove pathogens while reducing fecal coliform to less than 10 colony forming units per 100 mL. 800/753-3278; www.biomicrobics.com.
