Distribution and Diffusion Behaviors of Perfluorinated Compounds with Low Pressure Reverse Osmosis Membranes

Treatment of Phenolic Wastewaters by a Domestic Low-Pressure Reverse Osmosis System

In this paper, the removal of phenol by using aqueous solution in a low pressure reverse osmosis membrane was investigated. The effect of feed pressure, feed concentration, feed flow rate and feed pH on phenol rejection was investigated. The results showed that feed pH is the most affective parameter on the phenol rejection. Rejection of phenol increased with increasing pH from 2 to 10 under th...

A Novel Photovoltaic Powered Reverse Osmosis with Improved Productivity of Reverse Osmosis and Photovoltaic Panel

With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...

Rejection of Trace Organic Compounds by Reverse Osmosis and Nanofiltration Membranes

The Pursuits of Ultimate Membrane Technology including Low Pressure Seawater Reverse Osmosis Membrane developed by “Mega-ton Water System” Project

Reverse osmosis (RO) technology has been widely applied to water treatment such as seawater desalination, and large RO plants are many in operation around the world. Moreover, much larger plants will be required to secure sufcient water resource in the near future because global water shortage and quality problems are still getting more serious. Mega-ton Water System pr...

Reverse osmosis processing of organic model compounds and fermentation broths.

Post-treatment of an anaerobic fermentation broth was evaluated using a 150 gal/day, single cartridge prototype reverse osmosis (RO) system. Baseline tests were conducted at 25 degrees C using six organic model compounds representing key species found in the fermentation broth: ethanol, butanol, acetic acid, oxalic acid, lactic acid, and butyric acid. Correlations of the rejection and recovery ...
