Commissioning and Performance Testing a 6 MGD ZLD Drinking Water Treatment Plant
This presentation provides an overview of the commissioning and performance proving of a highly complex 6 MGD water treatment plant designed, built, and commissioned by CDM Smith. Located in the […]
Out With The Old – In With The New: Working With a Regulator to Replace 9-Year Old UF Membranes
Many older proprietary microfiltration and ultrafiltration (MF/UF) membrane systems have been in service long enough to require replacement of the membrane elements. This paper presents methods to specify and select […]
Replacing 7,308 Ultrafiltration Membrane Modules? A Supposedly Fun Thing I Will Do Again
Discussion of the complexities of replacing 7,000 plus membrane modules in a live water treatment plant with multiple stakeholders would be of great interest to membrane vendors, consultants and planners […]
Replacing the First Large Scale Municipal UF Membrane System in Illinois
This session would include either a 30 minute or 60 minute presentation on the events that led up to the replacement of the Lake Forest membrane filtration equipment. Lake Forest […]
Saving Money using a Single Source of Responsibility Membrane Replacement with Life Cycle Analysis – City of Melbourne Case Study
The evaluation and lessons learned during the membrane replacement process are applicable to other utilities looking at membrane replacement and how to consider upgrades of their existing RO systems with […]
Step-by-Step Procedure and Logistics of Replacing the 12 year old RO Membranes at the Five Forks Water Treatment Facility in Virginia
James City Service Authority (JCSA) has been successfully operating a 5.0 MGD brackish water RO plant since April 2005. Although the membranes were still meeting the water quality requirements, budget […]
Membrane Replacement, System Upgrades and Rehabilitation of a 25-Year-Old Nanofiltration System
This paper provides a summary of the membrane evaluation, condition assessment, evaluation results, design considerations for the system upgrade and a discussion of several items found during commissioning.
Performance of Super Enhanced Permeate Flow RO Elements With 3D Spacers Printed Directly on the Membrane Surface
Aqua Membranes has developed membrane feed spacers printed directly on the membrane surface. These spacers are thinner than conventional mesh spacers and allow up to twice as much membrane surface […]
Hollow Fiber Open Nanofiltration for Surface Water Treatment
This paper will detail the considerations that favoured hollow fiber nanofiltration membrane filtration over alternatives and design of a number of full scale plants. It will provide operational data of […]
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 […]
