The presentation will describe the basics of membrane technology with an introduction to reverse osmosis, microfiltration and ultrafiltration. The differnces in how the separations are achieved and how the processes opearate will be given. Examples of where RO, MF and UF are applied will be mentioned with particular attention to unconventional wate...

This presentation will review the treatment technologies and strategies that are used to treat oilfield produced water for recycling and beneficial reuse while concentrating brine to minimize disposal volumes....

This presentation will provide an update on the last four years of research funded by Reclamation on produced water technologies. Each technology has varying positive and negative aspects with respect to chemical requirements, energy requirements, footprint, cost, and removal capability. General information is included on a number of categories of...

Produced water from oil field in Colombia, with capacity of 500,000 barrels/day (21 MGD) normally discharged as wastewater, is treated for irrigation water using innovative membrane treatment processes is decribed in this presentation. The same treatment can be employed in well fields in US to recover produced water for beneficial use....

This paper reviews current thinking on reverse osmosis (RO) membrane cleaning. It challenges preconceptions and describes novel approaches for the removal of foulants and scale deposits from membrane surfaces. Improved cleaning practices are required as membranes are increasingly used in extreme water associated with enhanced oil recovery and minin...

The City of Missouri City, in conjunction with 30plus municipal utility districts within the city limits, completed a 10 MGD (first phase) regional surface water treatment plant to meet the Fort Bend County Subsidence District's mandates for reducing groundwater use. As a part of the facility, microfiltration membranes were utilized to meet both c...

Ideal applications for ceramic membranes include those in which the feed consists of emulsifed oily wastewaters at elevated temperatures. Select oily wastewater treatment applications will be desribed for both upstream and downstream oil and gas operations. Case studies will be presented in which the efficacy and resultant benefits of ceramic mem...

During the production of oil and gas, there is a significant amount of water produced during the recovery process. The ability to recycle and reuse this water in the field is of great importance and the paper will focus on methods used to make this happen. A variety of processes including membrane technology have been employed for treatment of pro...

With aging of oil wells, the ratio of produced water volume to oil volume is keep increasing. Produced water becomes a natural choice of water supply for oil production process. Thus, more and more oil producers are looking into produced water reuse. This is especially important for the regions where fresh water supply is limited, such as those in ...

Membranes are replacing conventional water treatment processes in multiple offshore applications. Two (2) seawater membrane systems, one (1) for potable water production and one (1) for water injection, will be considered and evaluated. Key drivers to why membranes have been accepted, such as weight, footprint and reliability, will be reviewed....

The last twenty years of the UF industry has been dominated by system manufacturers who provided their own proprietary modules and unique system designs. While this has changed somewhat in the past few years with the advent of the universal UF rack, a need has emerged from the base of installed capacity. Customers are looking for choices when purch...

This presentation will include a brief discussion of water membrane technologies and their applications in the petrochemical and refining industries, a survey of worldwide membrane installations for wastewater treatment and reclamation in petrochemical plants and refineries; and three representative case studies of using membrane technologies at th...

This presentation will discuss West Basin Municipal Water District as a case study for innovative uses of recycled water. In its 20th year of water recycling with membrane technologies, West Basin has cultivated an approach to providing its customers with fit-for-purpose designer water qualities. The discussion will include how West Basin treats se...

Forward osmosis (FO) is the membrane-based process by which a high osmotic potential stream (i.e., draw solution) is used to capture fresh water from a saline or contaminated feed water. The result is a highly concentrated brine and a diluted draw solution stream. The diluted draw is then processed for reconcentration of the draw species and recove...
