An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.
The innovative CoMag System from Evoqua infuses magnetite into chemical floc to make it heavier, significantly improving clarifier performance. This video explains how the CoMag® System works and how it can be used to increase capacity, enhance clarifier performance and achieve total phosphorous of 0.05 mg/L.
Fluence’s Membrane Aerated Biofilm Reactor (MABR) technology is an innovative wastewater treatment solution which saves up to 90 percent energy consumption. It is the ideal solution for decentralized applications such as rural villages, housing developments, municipalities, hotels, resorts, and golf courses.
Surrounded by agricultural fields where water is a vital resource, the rural region of Hayogev, Israel chose Fluence’s energy-efficient Membrane Aerated Biofilm Reactor (MABR) solution for wastewater treatment suitable for reuse.
As the cost of and demand for potable water increases, engineers, planners, and utilities need reliable, innovative methods for protecting this valuable resource. Cost-effective and environmentally sustainable wastewater collection and treatment systems are vital components in the water cycle and therefore require careful analysis. While there is no single solution for every site or community, traditional ‘big-pipe’ systems are rarely appropriate in sensitive environments; fortunately, today there are more options than ever to consider.

The SEPAREL PF series removes dissolved gases in water through a tube-shaped gas permeable membrane composed of polytetrafluoroethylene (PTFE). Gasses dissolved in water flow through the tube and are removed due to the pressure difference of the gases inside and outside of the tube, thus creating a vacuum outside of the tube. This video explains how the PF series works.
The SEPAREL EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. Also, a lower pressure drop means that larger modules can be used. This video explains how the EF series works.
The small SEPAREL EF series is optimized to remove dissolved gases in water applications with smaller flow rates. The EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. This video explains how the EF series works.
A proprietary technology of the DIC Corporation, SEPAREL hollow fiber membrane modules are optimized for degassing and aerating water. By utilizing an innovative surface skin layer, only gas can permeate in or out of the membrane. This video introduces the benefits of SEPAREL and where is it most commonly used.
