Report on the information gathering effort to develop a comprehensive historical account of the development and use of microfiltration and ultrafiltration. The Purpose of the study is set forth to aid in the operation of existing treatment facilities and to provide pertinent information to those utilities considering the future use of the technol...

This presentation is a basic description of membrane technology. It focuses on device configuration and covers both membrane filtration and membrane separation processes. Also discussed are the commercially available products, system photographs and applications of the technology....

The presentation funded by the California Energy Commission discusses a survey that was conducted to gather knowledge on membrane separation facilities. Survey results discussed include regional locations, capacity, water source, process used and water attributes. Also covered are treatment objectives, chemicals used, plant initial and O&M costs....

Membrane distillation is a desalination process where a vapor pressure gradient drives the diffusion of water across a hydrophobic membrane. Benefits of membrane distillation include extremely high salt rejection (100% theoretical rejection), permeate quality that is independent of feed salinity, utilization of low grade waste heat, and operation ...

There is a growing movement to treat Produced Water as a revenue generating resource instead of a waste product. Advanced water treatment technologies including membrane filtration, membrane bioreactors (MBR) and membrane distillation are discussed including case study references. Some guidance is provided regarding the development of various tec...

This paper summarizes the results of both bench and pilot-scale Membrane Distillation tests when treating a variety of feedwaters including thermal desalination system brines, seawater, tap water and prepared sodium chloride solutions. In addition to measuring flux & effluent quality as a function of process conditions (temperature, flows, salinity...
