Fundamentals of Monitoring Membrane Filtration Plants
Membrane filtration plants are complex systems which involve monitoring of varied types of data for performance and maintaining operations. This presentation willl present the different types of data encountered in treatment plants and how each type is used to monitor the system and react to changes. Examples from Colorado treatment plants and SCADA HMI screens […]
Lessons Learned at the City of Thornton’s MF/UF Wes Brown Water Treatment Plant
The City of Thornton transistioned from ferric chloride to aluminum chlorohydrate coagulant in 2019 and has seen specific flux/temperature corrected permeability (TCP) values return to what was observed after 2-4 years of use with ferric chloride in membranes in their 7th to 9th year of use. The City continues to optimize coagulant dose for TOC […]
Lessons learned when combining pretreatment with MF ceramic membranes
The Rueter-Hess Water Purification Facility is a state-of-the-art treatment plant which utilizes ceramic micro-filtration membranes for pathogen removal. From the commissioning in 2015 to today, many lessons were learned about the impacts that proper pretreatment can have on the permeability of our membranes. We will share some hard learned do’s and don’ts when combining pretreatment […]
Foulant Identification at Midwestern MF/UF Membrane Plants
This presentation focuses on the types of fouling that are currently being experienced at a variety of MF/UF membrane plants in the Midwest. The discussion includes how the foulant materials are setting up in the MF/UF membrane elements and how the autopsy process is being used to identify foulants and provide solutions for their removal. […]
Lessons Learned Designing and Operating Membrane Filtration Systems
Implementation of Membrane Gravity Filtration (MGF)
Membrane Gravity Filtration (MGF) is an application for retrofitting gravity media filters using ultrafiltration membranes. It combines the simple operation of a media filter with the superior treated water quality of a UF membrane. MGF is best suited for applications where customers need better turbidity removal, a barrier to pathogens, or need to significantly increase […]
Lessons learned from design and operation of Membrane Bioreactor (MBR) Facilities
This presentation presents the progress and applications of MBRs which provides the benefit of biological treatment process in a compact footprint and solids liquid separation for a high-quality effluent. In this paper, lessons learned and challenges from design and operation of MBR plants are presented. MBRs provide the pretreatment required for other treatment technologies such […]
Membrane Bioreactor (MBR) Troubleshooting
An overview of several typical issues that plague MBR systems, and how to troubleshoot them. The presentation will also include a quick overview of common design issues we run into that can contribute to operational issues.
Membrane Bioreactor – Alternatives Analysis Review
This presentation is a wastewater treatment case-study of an existing sequencing batch reactor (SBR) retrofit with a Membrane Bioreactor (MBR). AQUA Engineering is pleased to discuss the Project’s workflow, including review of project drivers, alternatives analyses, and reasons for the selection and implementation of MBR technology.
Understanding Rejection: The Path to a Healthy Membrane Life
This presentation is all about membrane rejection, how to calculate it, where to sample for it, and what the numbers are telling us. Knowing how to collect and analyze this information on a RO membrane system will allow an operator to setup a conductivity profile and then a rejection profile for all parts of the […]
