Although the technologies involved in converting saline gradient energy (SGE) are rapidly developing, few studies have focused on evaluating possible environmental impacts. In this work, impacts of a hypothetical 50 kW RED plant installed La Carbonera Lagoon, Yucatan, Mexico, addressed. The theoretical support was taken from literature review and analysis components pressure retarded osmosis (P...

Corn steep water as effluent which arrives in environment from starch processing industry has adverse effects on the environment and also large volume of fresh water is wasted. Corn step water is composed of high concentration of proteins, sugar, starch, vitamin and minerals, so it can be used as substrate for production of biological products. Hence, corn steep water concentration is important...

Ionic polymer hydrogels with thermal responsive units are found to induce higher water permeation rates in the osmosis process, and higher water release rates under a combination of pressure and thermal stimuli. These hydrogels have the potential for use as draw agent in forward osmosis desalination.

It is shown that by combining the osmotic pressure and rate of diffusion laws an equation can be derived for the kinetics of osmosis. The equation has been found to agree with experiments on the rate of osmosis for egg albumin and gelatin solutions with collodion membranes.

Reverse osmosis (RO) is being increasingly utilized throughout the world for desalination due to the latest improvements in RO membrane performance and its reduced cost compared to thermal desalination. In this paper, Different media and chemicals have been used for Iron removal to prevent membrane fouling of groundwater reverse osmosis plant located in Shupramant-Giza. The objective is to pres...

Big gap between experimental filtration resistance of cake layer formed on membrane surface and the hydraulic resistance calculated through the Carman-Kozeny equation, suggested the existence of a new membrane fouling mechanism: osmotic pressure during cake layer filtration in SMBR system. An osmotic pressure model based on chemical potential difference was then proposed. Simulation of the mode...

The movement of water by osmosis causes pressure differences that drive the transport of sugars over long distances in plants.

The energy requirements for desalination have made it an expensive process, however, is still a viable and cost-effective means of water purification amidst freshwater scarcity. management disposal brine external extra cost due to the effect on environment. integration Pressure Retarded Osmosis (PRO) with Reverse (RO) technique as modelled in this paper enhances management. fed back into PRO un...
