Single-Family, Decentralized Membrane Bioreactor Systems that Meet Future Effluent Standards

How BioBarrier MBR InstallsA new generation of wastewater treatment solutions bucks the trend to large centralized treatment plants and complex sewer networks.  The BioBarrier® membrane bioreactor (MBR) helps to meet the increasingly stringent needs of water quality standards, site issues, and water reuse applications.

How BioBarrier MBR WorksThe BioBarrier® MBR was the first system certified for water reuse (NSF/ANSI Std 350, class R) for total blackwater and greywater recycling.  BioBarrier’s high-quality effluent provides new opportunities for wastewater recycling techniques that will have dramatic, positive effects on water resources around the globe.

This simple, low-cost, and robust MBR system uses advanced technology to offer the highest quality effluent possible on the market. The pre-engineered, modular MBR ships installation-ready and fits easily into both new and existing tank configurations. The membranes and processes used in this advanced system act as an impenetrable physical barrier for nearly all common pollutants found in wastewater today. BioBarrier’s low-foul, durable, flat-sheet membranes utilize micro-sized pores for physical separation of solids from the wastewater. The system’s unique operation sequence requires no complicated backwash functionality and is completely automated using an advanced control strategy.

BioBarrier® MBR system is designed specifically for the unique needs and characteristics of the onsite and decentralized wastewater industry making it the most advanced system on the market. The BioBarrier®-N adds an additional anoxic zone to achieve higher Nitrogen reduction for environmentally-sensitive areas.

Finding the right size…

BioBarrier® treatment systems are engineered for residential strength wastewater in three specific sizes based on daily wastewater flow. The flow for a residence is usually determined at the local regulatory level. Typically each bedroom is assigned a value for the number of GPD of wastewater it will contribute to the overall sewer.

Product Certifications

Our products are certified to the highest national and international standards in our industry. If you require additional certification marks, etc, please e-mail your request to

USA and International Product Certifications

The list below is a summary of a few certifications received for the products of BioMicrobics:

  • NSF/ANSI Standard 40, Class 1 Certified (BioBarrier® 0.5, 1.0, & 1.5) – NSF (National Sanitation Foundation International) tests residential wastewater treatment systems having rated capacities between 400 gallons (1514 Liters) and 1500 gallons (5678 Liters) per day. The Standard 40 includes a wide range of product evaluation methods and criteria for residential treatment systems. Most notably is the ability of the treatment system to produce an acceptable quality of effluent. This is demonstrated during a six month (26 week) test where wastewater of required strength is subjected to the system at the rated capacity of the system as evenly dosed at periods prescribed by the standard. Stress sequences are included to simulate wash day, working parent, power outage, and vacation conditions. The effluent criteria required of a Class I system is based on the U.S. EPA secondary effluent treatment requirements for municipal treatment facilities. In addition to the effluent performance, requirements also exist for product literature, including installation, operation and maintenance, and trouble shooting and repair manuals. The system must also meet minimum requirements for structural integrity, leakage, noise, electrical certification, access ports, failure sensing and signaling equipment (visual and audible alarms), flow design, data plate and service labels.
  • NSF/ANSI Standard 245 (Nitrogen Reduction) Certified (BioBarrier® 0.5, 1.0, & 1.5) – Developed for systems to provide acceptable levels of nitrogen reduction. The evaluation involves six months of performance testing, incorporating stress tests to simulate wash day, working parent, power outage, and vacation conditions. Throughout the testing, samples are collected during design loading periods and evaluated against the pass/fail requirements. A treatment system must meet the following effluent concentrations averaged over the course of the testing period in order to meet Standard 245 (CBOD5=25 mg/L, TSS=30 mg/L, Total Nitrogen=at least a 50% average of influent TKN, and pH=6.0 to 9.0 SU).
  • NSF/ANSI tested for bacterial reduction of fecal coliform (BioBarrier® 0.5, 1.0, & 1.5)
  • NSF/ANSI Standard 350, Class R (Water Reuse) Certified (BioBarrier® 0.5, 1.0, & 1.5 – FIRST system to achieve this Standard!) – Developed for residential wastewater treatment systems designed to provide for water reuse onsite. The evaluation involves 6 months of performance testing, incorporating stress tests to simulate wash day, working parent, power outage, and vacation conditions. With a key focus on public health and appropriate water quality criteria for reuse applications; this is the first standard of its type for comprehensive evaluation of water reuse technologies, spanning residential and commercial applications. Technologies testing against Standard 350 must meet Standard 40 and 245 prior to testing.
  • EN 12566-3 (European Union Standards) – Packaged and/or site assembled domestic wastewater treatment plants for up to 50 People
  • All Control Panels – CSA (Canadian Standards Association) Electrical Certification CSA International and the International Association of Electrical Inspectors (IAEI), the Electrical Safety Foundation International (ESFI), Health Canada, provincial regulators, and the U.S. Consumer Product Safety Commission (CPSC) to promote standards for consumer safety in North America and around the world. CSA testing is accepted by key conformity assessment organizations in the U.S. including IAPMO and ASSE. Tested and meets applicable standards for safety and/or performance, including the applicable standards written or administered by the American National Standards Institute (ANSI), Underwriters Laboratories (UL), Canadian Standards Association (CSA), National Sanitation Foundation International (NSF), and others.
  • All Control Panels – CE – European Electrical Systems (including a “Tropical Certification Rating”) The European (EN) standards by adopting universal requirements to cover all of Europe and promote the free movement of goods within Europe. When products have been shown to meet the essential requirements of the directive or EN standard the product is available for sale anywhere in the European market.
  • All Control Panels – ETL and RoHS Compliant – Intertek Testing Services Evaluated and meets the standard equivalent to the requirements set by Intertek and equivalent to UL (Underwriter’s Laboratories). Periodic checks are performed to assure consistent compliance of the product and in compliance with both Canadian and U.S. requirements.
  • FOGHog® Fat Oil & Grease Interceptor FH-20 & FH-50 – IAPMO Certified– IAPMO (International Association of Plumbing & Mechanical Officials) developed a Uniform Plumbing Code and Uniform Mechanical Code that is adopted by plumbing and mechanical engineers who follow these standards of uniformity to promote professionalism within the industry. Using the ANSI-accredited organization method, which is based on consensus, these codes set the standard for engineers to perform plumbing and mechanical duties uniformly, according to IAPMO standards of certification. Several states are or have considered making Mechanical or Plumbing Inspector certification a requirement for current or prospective inspectors.
  • All Control Panels – SASO (Saudi Arabian Standards Organization) Electrical Standards The Saudi Arabian Standards Organization approves national standards and measurements for all commodities and products, methods of sampling, inspection and testing, in addition to other assignments resolved by SASO Board of Directors in the Kingdom.
