Operational Improvements with Immersed Membranes for Municipal Drinking Water Treatment
This paper presents recent pilot test results at four different locations showing substantial improvements on settled and coagulated water sources while providing permeate quality that meets current and proposed regulatory guidelines. Pilot studies described were performed with Zenon Membrane Solutions ZeeWeed 1000 product....
MBR/MF/UF Technology Status and Trends
This presentation describes the MF-UF market as it stands today compared to 10 years back. Water treatment and MBR plants are larger. TIPS no longer an exclusive fiber. Dicusses practice in North America, Europe and Asia. Discusses integration of UF as pretreatment for RO.....
Overview of Low, Medium, and High Pressure Membrane Systems
This PowerPoint gives and overview of low, medium and high pressure membrane systems....
MF/UF Developments: Universal Rack Design and Process Convergence
This presentation discusses the evolution of the microfiltration (MF) and ultrafiltration (UF) membrane market, standardization in membrane module design and process operations, and the universal rack concept. MF and UF manufacturers are listed and module interchangeability between manufacturers is discussed. The presentation concludes with a summa...
Introduction to Nanofiltration and Reverse Osmosis
This presentation provides an overview of reverse osmosis and nanofiltration technologies for water treatment. It includes definition of terminology, theory, and description of equipment and key issues for operation....
Membrane Retroft of Conventional Water Treatment Plants Applicability, Examples and Lessons Learned
The use of membrane systems in municipal applications can be divided between new green field plants and retrofit of existing conventional filtration facilities. Both types of construction have their benefits and drawbacks depending on the application, site conditions and age of the existing infrastructure. Using a retrofit approach can be very bene...
Microfiltration and Ultrafiltration Standardization - A Review of Current Mechanical and Process Convergence and a Look Forward.
Without a standard approach to process and mechanical convergence of MF and UF treatment systems, end users and consulting engineers continue to deal with one-of-a-kind, non-interchangeable and incompatible systems. This does not help in expanding the low pressure membrane adoption from a technical and cost perspective. This paper will review the p...
Interchangeable MF/UF: Lessons from the Most Recent North American Projects in Operation and in Design
This paper provides an overview of the current status on the Interchangeable, Flexible, Universal or Open-platform MF/UF systems. Cost competitiveness, adoption into projects specifications through the eyes of the first projects built, and the extension to piloting requirements are explored over the last 18 months....
Case Study: Delaware UF & RO Facility
The City of Delaware operates an integrated membrane facility with three Ultrafiltration and five Nanofiltration trains. The Ultrafiltration units are used as a pretreatment to three of the nanofiltration trains which are used to primarily reduce hardness in the feed water. The two remaining Nanofiltration trains are used to treat ground water with...
