Savings Helps MABRs Gain Traction In Municipalities
Savings Helps MABRs Gain Traction In Municipalities

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.

Aspiral™ is a smart, packaged wastewater treatment solution based on the Membrane Aerated Biofilm Reactor (MABR) technology.

MEMBRAY® NHP-Series MBR MEMBRAY® NHP-Series MBR

As part of Toray’s MEMBRAY MBR series, the NHP (New High Performance) module features thin membrane flat sheets that are densely packed into easily interchangeable cassettes. These cassettes allow for a higher packing density than what was originally thought possible with flat plate designs. The thin membranes are also highly flexible and allow for more movement, resulting in increased vibrations during aeration. This helps dislodge sludge and improve cleaning efficiency, all with less energy use.

SEPAREL® PF Series SEPAREL® PF Series

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.

SEPAREL® EF Series SEPAREL® EF Series

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.
