Microfiltration (MF) process data from the Marquette and Kenosha membrane filtration plants are also presented. The presentation concludes with recommended design considerations and operating practices for the treatment of Great Lakes surface water....

Presentation will focus on the basics of MF/UF Membrane filtration. Topics will include the basic types of membranes, materials of construction, glossary of terms used, and basic application parameters for consideration by someone seeking to apply MF/UF technology....

This session covers intergrity testing theory and application for hollo fiber membranes. Attendees will receive backgound of what intergrity is and how it applies to daily memrbane operations, along with startegies and approaches to manage membrane intergrity in a practical setting....

The City of Hermiston installed an Membrane Bioreactor in 2014 to replace an existing RBC plant. The plant has been operating for over a year now with good results. The challenges associated with startup of a new membrane plant will be discussed. Other topics include the reasons for the upgrade to an MBR system, operation of the existing plant d...

This paper describes the application of a double ended submerged filtration system in Sydney Australia. Several different modules were tested and high turbidity experienced during the test period were handled effectivity and showed that the method was sound. Test results are presented....

This PowerPoint presentation outlines the pilot testing at the Wheeling, WV location. A microfiltration system was installed and the performance test on startup is discussed with results presented....

The aim of this study was to assess temporal changes in log removal values (LRV) for a suite of microorganisms, for time scales relevant to the expected life of modern MBR modules. A higher level of fouling on the older membranes likely improved rejection, although not consistently, when compared to new clean membranes. Larger bacteria and protozoa...

This paper discusses the Rimini WWTP in Europe and the application of the MBR system in 2015 as the biggest MBR plant in operation in Europe. This increasing of capacity was due to centralizing some WWTP?s in the area. The new design foresees common pretreatment, then the wastewater is split in two lines: existing CAS line and new MBR line. The pa...

This discussion examines the current state of MBR technology in North America and seeks to present thought provoking discussion on where the MBR technology is going in the the future. The presenation examines both municipal and industrial applications, alternative technologies, resue appilications, and overall MBR system optimization opportunies....

This presentation provides an overview for the selection, design, implementation and operations of Upper Hocking WWTP. The rationale for selecting the MBR process will be reviewed, answering the "why MBR?" The design and implementation covers construction cost and start-up lessons learned. The operations section highlights operating data since star...

This discussion examines the current state of MBR technology in North America and seeks to present thought provoking discussion on where the MBR technology is going in the the future. The presenation examines both municipal and industrial applications, alternative technologies, resue appilications, and overall MBR system optimization opportunies....

Discusses how progressive design-build project delivery approach was used to successfully deliver the first universal rack membrane filtration system in Pennsylvania. Topics to be addressed include the challenges of implementing a universal membrane rack system and the advantages and disadvantages to the progressive desig-build approach....

This presentation describes a systematic approach to the examination of fouled membrane modules and the development and validation of preferred cleaning procedures, illustrated by case study data. Through experimental design and case studies, we show that cleaning study data must be interpreted carefully to maximize the prospect of restoring module...

When making improvements to membrane treatment products, it is important that all aspects of product performance and longevity be thoroughly investigated to maximise the value of the improvements. This presentation describes testing done in a full-scale MBR plant in California to validate a product improvement in a novel way, and some of the accel...

This presentation presents data and application perspective on how to apply a DIT in a MBR setting. It's value is in presenting a data-driven perspective to the application of DIT in a MBR to be considered as a credible alternative to only turbidity monitoring....

This presentation will provide the attendees with a fundamental understanding of the MBR process technology. Various system confiurations, materials of construction, and basic application priciples. Discussion of the basic subsystems of a MBR will be included as well....

This presentation discusses the causes and solutions for fouling problems with MBR processes. We will review the impact of the biological treatment, influent loads, influent constituents, and ancillary systems have on the MBR process. We will further discuss and present a troubleshooting framework on identifying the source of fouling and how to re...

The Borough of Mifflinburg Municipal Wastewater Treatment Plant located in Mifflinburg Pennsyvania recently went through a Membrane Replacement Project and installed Evoqua's B40N membrane modules with Mempulse technology. The results were located in Mifflinburg Pennsyvania. The plant upgraded their membranes, aeration system, and mixed liqour di...

Advanced wastewater process technologies offer power companies a feasible approach to compliance with national and state regulations. This paper presents alternative scenarios where an ultrafiltration (UF) process is applied after a biological treatment process to polish water prior to discharge. We present how the UF process enables the power comp...

The early generation of reinforced hollow fiber submerged membrane systems for drinking water treatment are coming due for membrane replacement. In many cases the Membrane Filtration Guidance Manual practices for integrity management have been codified since these systems were installed, and it is difficult to apply all aspects of those practices t...

This paper presents the planning and execution of the conversion of three existing UF skids at a power generation station in Indiana. The approach was deliberately minimally invasive to minimize the installation downtime and the extent of the process changes....

This paper will describe the use of a unique organics characterization method, liquid chromatography with on-line carbon detection to identify the primary cause of organic fouling in two fouling scale ultrafiltration plants, biopolymers and cTEP, and how the LC-OCD results were used to mitigate the impacts of these foulants through optimization of ...

The presentation will be a look at how the hollow fiber membranes are made, tested, shipped, and installed (without discussing any trade secrets). We will focus on the polymeric hollow fiber technology, discussing the various production methods, QC under the MFGM, and best practices to ensure quality in installation....
