Uriel Klar, Business Analyst at Fluence Corporation, explains the MABR technology and its applications. Please describe the MABR technology Membrane Aerated biofilm reactor (MABR) is a biological wastewater treatment process that utilizes passive aeration through oxygen-permeable membranes. The MABR aeration process is the most efficient oxygen delivery system for treating domestic wastewater. ...
Aerobic digestion and nitrification-denitrification work together thanks to an innovative membrane system One of the most talked-about new wastewater treatment technologies is the membrane aerated biofilm reactor (MABR), which is revolutionizing WWT. The discussion, however, has mainly focused on issues like MABR technology’s low operating expenses, high energy efficiency, low ...
A Membrane Aerated Biofilm Reactor (MABR) manufactured by Fluence Corporation (Fluence) was installed at Stanford’s Codiga Resource Recovery Center (CR2C) in January 2018. The system was tested with domestic wastewater diverted from Stanford’s sanitary sewer. Treatment performance was evaluated according to two benchmarks: California Title 22 standards for non-potable water reuse (T22) and a ...
Aerobic wastewater treatment ranges from the simple to revolutionary technologies like MABR, which saves energy and is ideal for decentralized treatment Aerobic wastewater treatment takes many forms, but fundamentally it’s a biological process widely used in the treatment of both domestic and industrial wastewater, particularly waste streams high in organic or biodegradable content. ...
In Fluence’s membrane aerated biofilm reactor (MABR) technology, simultaneous biological nitrification-denitrification takes place within a single tank due to a bacterial biofilm that forms on its aeration membrane. Nitrates, which are vital to the growth of plants, must be removed during the wastewater treatment process Nitrogen, the most prevalent element in Earth’s atmosphere at ...
Nitrates, which are vital to the growth of plants, must be removed during the wastewater treatment process Nitrogen, the most prevalent element in Earth’s atmosphere at 78%, can be found in living organisms and decaying matter like humus in soil, as well as in the air we are breathing right now. Nitrogen is considered a vital limiting nutrient, which means that in nature, it typically is ...

Project on San Francisco Bay protects from storm surge and purifies water On the eastern shores of San Francisco Bay, the Oro Loma Water District is reimagining the concept of the traditional levee into the “horizontal levee,” an idea proposed by consulting ecologist Peter Bay and Jeremy Lowe of Environmental Science Associates. The horizontal levee starts with an already existing ...
Filtering out contaminants, even at the nano scale, membranes are a mainstay of water and wastewater treatments In water treatment, membranes are barriers that allow water to pass through but stop unwanted substances from passing through with it. Working much like the cell walls in our bodies, technical membranes filter out salts, impurities, viruses, and other particles from water. A membrane ...
MIT researchers conclude that alternative approaches to water planning can alleviate urban water supply issues quickly and inexpensively Urban areas around the world are expanding rapidly as the global population increases and people are moving to cities at a fast pace. This puts a strain on current infrastructure, including water treatment plants. Add global warming and increasing drought ...
Distributed treatment, which limits the need for fossil fuels and extensive infrastructure, could be a perfect fit for the islands’ needs Among water treatment industry professionals, consensus is growing that small- to medium-scale decentralized desalination and wastewater treatment plants are the way forward in a water-stressed future.
