The use of forward osmosis (FO) is of growing interest for water desalination, due to its potential energy savings. However, its industrial implementation is still limited by its actual performance limitation inwater permeation and reverse salt diffusion, due to membrane properties. Assisted forward osmosis (AFO) is a new concept, aiming at pressurising the feed solution to enhance water permea...

Water contamination by micropollutants is increasing, including steroid hormones. Indiscriminate use, incorrect disposal, inefficient treatment of water and effluents, less restrictive legislation promote the effluents water, with harmful consequences for environment human health. In this work, it was evaluated use reverse osmosis in removal ethinylestradiol levonorgestrel, synthetic steroids t...

Reverse osmosis is a widely used desalination technique, mainly because of its low specific energy consumption. Autonomous reverse processes are increasingly developed their efficiency and the decentralization numerous water stress areas. In this context, process powered by an innovative thermo-hydraulic system using heat has been developed. This new aims to autonomously produce fresh from brac...

An often-overlooked source of marine renewable energy is the energy available from salinity gradients. The potential resource for the osmotic pairing of fresh water and seawater is estimated at 2.6 TW. Several concepts have been proposed. Obviously, any scheme to desalinate seawater can be operated in reverse. Recent developments in pressureretarded osmosis, vapor compression, reverse dialysis ...

Wastewater produced by the crew members on a long-term space mission needs to be recovered as potable water. Reverse osmosis (RO) has long been in use as a physical membrane separation technology for wastewater treatment. However, membrane fouling and concentration polarization have limited the efficiency for high recovery reverse osmosis systems. An advanced high pressure rotating RO device wa...

The shrinking water supply together with our continuously increasing demand for this resource has stimulated a renewed interest in reverse osmosis (RO) as a water treatment unit process. A wider use of RO membranes, however, is impeded by a group of phenomena that lead to permeate flux decline, deterioration of permeate water quality, shortening of membrane life, and thus to a substantial incre...

The conversion of saltwater and brackish water into fresh through desalination has gained significant importance as a solution to the worldwide scarcity resources. Reverse Osmosis (RO) method been effectively utilized generate from sources water. This research aims examine variables that affect performance reverse osmosis process. effectiveness membrane was assessed experiments explored impact ...
