This paper compares membrane treatment to conventional treatment in municipal and industrial applications....

This presentation discusses the pilot study results for the Canyon water treatment plant in the city of Azusa CA. Also discussed is membrane basics, evaluation and water properties. In the actual case study the reader is walked through the decision making process including several side by side pilot tests. Results are then compared looking closely ...

Discussion of concentrate disposal handling for desalination RO facilities....

Paper summarizes a pilot program that was conducted for Marin Municipal Water District (MMWD) on San Francisco Bay, California water. The seawater RO desalination pilot program compared two pretreatment technologies: 1. Conventional Pretreatment with coagulation, clarification, and granular media filtration to 2. Membrane Filtration with microfiltr...

The City of Goodyear is using RO to reduce the TDS level in the well source water to achieve potable water with TDS < 750 mg/L. The concentrate is currently being discharged into the wastewater treatment plant. As the City grows there is concern that the brine will adversely impact the wastewater treatment plant. This paper summarizes the techni...

Membrane bioreactors (MBRs) have several advantages over conventional treatment technologies using tertiary filtration. This paper covers some of the fundamentals of MBR and includes comparative information for evaluating common membrane technologies used in MBR applications....

This paper provides a brief history of membranes, the characteristics of the different types of membranes, and the exponential growth in the number of installations. Applications for water, wastewater treatmentwater reuse and desalination, and the challenges that membrane treatment processes face are also presented. The presentation will conclude w...

This paper compares side by side two main classes of water bodies that receive concentrated brine discharge from Reverse Osmosis (RO) Desalination Plants: oceans (or open seas) and estuarine bays (under the influence of fresh water). These two classes of water bodies have inherent properties which drive not only the operation of RO plants, but also...

This presentation will provide a brief recap on RO technology current status, trends in RO developments and potential combination of using RO with FO technology....

Presents how RO technology is applied in different types of feedwaters by modifying the arrangement of commercially available membranes within the RO system....

This paper presents methodology, concept and results of the WateReuse Foundation project WFR - 09 - 06b when developing high pressure membranes, Reverse Osmosis (RO ) and Nanofiltration (NF) online membrane integrity testing (MIT) technique. The use of pressure-driven membrane processes, particularly reverse osmosis (RO), has grown significantly ov...

This presentation will discuss the possibilities and constraints of various approaches to design of RO units for different applications. Advantages and limitations associated with different configurations will be discussed and illustrated through design examples. A practical approach to the selection of membrane elements and system configurations w...

Direct potable reuse is now being considered a feasible opportunity and has the attention of many. Global warming, climate change, and drought has made water scarcity a top of mind issue for many communities across the country. Water scarcity is not a new challenge for communities, yet a long standing problem. While non-potable reuse is not a new c...
