This presentation covers important parameters to monitor from a management perspective when operating a membrane plant. The most critical factor is the quality of raw water. For fairly unstable raw water, need to monitor much more often. Some of the parameters to consider include Silt Density Index; bacteriological; turbidity; Total Dissolved So...

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.....

This presentation describes the history components function and programming of a PLC....

This presentation describes the need for benchmarking electrical energy usage in an RO plant; describes how to set up a spreadsheet, and populate it with the information needed. Also considers similar approach for other cost centers in the plant....

This PowerPoint gives and overview of low, medium and high pressure membrane systems....

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...

This presentation documents differences between municipal and industrial treatment projects with respect to membrane filtration (microfiltration and ultrafiltration) and membrane desalting (nanofiltration and reverse osmosis) processes. The presentation also provides example applications for membranes within various industrial markets. Industries t...

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....

Over the last few decades Membrane Bioreactors (MBR) have transitioned from a new innovation to a conventional, trusted approach to advanced wastewater treatment. Like any other wastewater treatment process the key to succesful MBR operation lies in understanding how they work, why they work and some important factors that affect their performance....

The automation industry has transformed rapidly over the past decade, which has enabled the growth of MF/UF technologies. MF/UF technologies need advanced control systems by their nature. The number of actuated valves and well timed control sequences required of modern systems has helped keep capital costs lower by minimizing non-production time o...

This paper provides a brief History of RO/NFand explains the basics Concepts of Osmosis and RO membrane separation mechanism. It also provides information about membrane selection, average Flux estimate, membrane area required/number of membranes and use of computer Projections to determine the system?s needs....

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...

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....

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...

Water source changes, temperature change, cleaning protocol, mechanical failures are a few of the causes that effect production and membrane life. We will look at these different components and processes of membrane systems and how to troubleshoot them. We will also look at some real life examples and how the troubleshooting process took place....

This presentation provides an overview of membrane bioreactor (MBR) processes and identifies options for incorporating flexibility in design. Several case studies are presented that show examples of flexible MBR designs while highlighting the suitabiblity of MBR as a technology for retrofitting existing wastewater treatment facilities....
