This paper will review several commercial operations and recent pilot plant test results and economics for the use of hollow-fiber ultrafiltration membranes for pretreatment to spiral RO brackish water and seawater desalination systems...

This presentation is an introduction of membrane technology. This covers the basics of how reverse osmosis technology works as well as a basic understanding of the all the variables and details that must be understood to apply the technology. Also covered are basic system design consideration basics....

Discussion of the development of large diameter seawater elements (18")....

Remote monitoring via Supervisory Control and Data Acquisition (SCADA) of ultrafiltration (UF) is discussed as a tool for gathering system production and performance statistics, monitoring systems for tampering or attack and to diagnose process and equipment problems early before they become catastrophic or cause equipment damage. Remote monitoring...

This presentation discuss' how features of a new MBR module make it particularly applicable to large-scale MBR plants. Features such as an optimized permeate extraction manifold and air supply lines reduce the number of piping connections during installation. To simplify membrane cleaning and maintenance, the proprietary central aeration system an...

Koch? membranes are used in a variety of MBR applications from small package systems to large wastewater treatment plants. This paper includes product information and a look at innovation in terms of energy efficiency. Several case studies are provided for reference....

The mission of the Affordable Desalination Collaboration (ADC) is to promote seawater desalination using reverse osmosis (SWRO) as an affordable, viable source of fresh water. In order to accomplish this mission the ADC conducted a multiphase pilot taking feed water from the Pacific Ocean (Navy intake at Port Hueneme, CA). This paper contains pil...

In summary, the RO systems at the Village of Tequesta have performed almost flawlessly, have required little maintenance and needed no cleaning in eight years of operation....

Membrane Bioreactors (MBRs) are widely accepted today for the treatment of industrial and municipal wastewater. Benefits of MBR technology over alternative technologies include superior water quality and reduced footprint. The energy consumption of MBRs however, is greater than the energy consumption of a conventional activated sludge (CAS) plant. ...

The discharge of wastewaters by industry is subject to stringent regulation by local, municipal, and federal agencies. Although regulations may vary, the need for improved pretreatment is generally recognized and is being enforced. Cross flow membranes provide best available technology - in a cost-effective, reliable, and less labor-intensive way...

This presentation provides an overview of the water treatment process for Palm Beach City in Florida. The Process Flow Diagram is provided. The objective of this membrane Softening plant is to reduce Hardness, TOC and Color. The presentation also provides characteristics of the raw water, finished water and concentrate....

Ultrafiltration is an effective method of treating wastewater so that it can be used as reuse water. This can also be considered pretreatment to treatment of the wastewater by reverse osmosis/nanofiltration membranes. Coagulant aids will sometimes greatly improve solid removal in the ultrafiltration treatment....

Koch Membranes will present how innovations in membranes and MBR design have led to increased efficiency and maximum throughput in wastewater management. KMS will present specific examples of how innovative MBR technology has been utilized to successfully solve challenging wastewater problems globally....

This paper will describe the benefits of tertiary ultrafiltration technology, often combined with RO treatment for reuse projects primarily for industrial purposes, to meet the reuse water quality targets. The paper will focus on a pressurized ultrafiltration product with supported outside-in hollow fibers for treating secondary and tertiary efflue...

The Chesapeake Bay Watershed Initiative (CBWI) of 2010 required many wastewater treatment plants discharging to affected waterways to meet progressively lower effluent contaminant levels. While the initiative's impact was felt most profoundly by municipal plants that now had to meet lower nutrient limits, it also affected many of the area's industr...

This presentation describes how the town of Riverhead, NY, is saving 100 million gallons per year of potable water by reusing its wastewater for landscape irrigation. The existing SBR basins were converted into a unique batch-style membrane bioreactor (MBR) while maintaining capacity and treatment during the upgrade. The design flow increased from ...
