The Case for Removing Post-Disinfection from MBR Treatment
This paper shares data collected over five years from more than 10 MBR facilities in North America, Europe and Australia to offer a benchmark of the long term ability of full scale MBR installations to provide high levels of microbial removal. The facilities that were sampled all used ZeeWeed UF membranes, selected to include varying membrane ages,...
The Case for Removing Post-Disinfection from MBR Treatment
A tremendous amount of pressure is put on municipalities to provide higher-quality effluent within increasingly constrained capital and operating budgets - they are required to do more with less. Wastewater treatment industry stakeholders should strive to understand and prove the capabilities of technology so as to enable the implementation of the ...
Tap Into MBR - The Hamby WRF Indirect Potable Water Reuse Project
The Hamby WRF project is an important drought resilience planning project where indirect potable water reuse is being applied successfully. Execution of such a project comes with a variety of challenges and lessons learned. An important difference between this projects and others is the use of MBR in a potable reuse scheme. With the plant in operat...
A Simple Measurement of MBR Membrane Integrity That Goes Back to Basics
The difficulty in monitoring pathogen removal is a gap that has been identified in the adoption of Membrane Bioreactors for IPR/DPR. This paper presents a newly proposed method for the calculation of solids LRV across the MBR system. The new method relies on the widely used standard method for enumeration of total suspended solids with a modificati...
MBR in Refinery Applications - Meeting Tough Discharge Standards and Enabling Reuse
Refineries are facing challenges associated with processing increasingly variable crude slates, more stringent discharge requirements, and regional scarcity of freshwater resources. MBR technology provides the ability to treat wastewater to higher standards with the option to reuse the treated effluent as process water. The refining industry is typ...
