Osmotic power, salinity gradient power or blue energy is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO). Both processes rely on osmosis with membranes. The key waste product is brackish water ...
A leak Saturday afternoon pumped 15,000 gallons of sewage in the Pacific Ocean, causing closures at Venice Beach and Dockweiler State Beach. 15,000-gallon sewage leak triggers closures at two L.A ...
To pump water from the tanks, there were two 24-inch (61 cm) discharge pumps on each section, each pump rated 15,000 US gallons (57,000 L) per minute. For electricity, there were two 350-kw diesel AC generators on each section, producing 440 volts 3-phase 60-cycle power. AFDBs had steam plants to run the pumps. Each section could store 65,000 ...
Overdrafting in coastal regions can lead to the reduction of water pressure in an aquifer, allowing saltwater intrusion. If saltwater contaminates a freshwater aquifer, that aquifer can no longer be used as a reliable source of freshwater for settlements and cities. Artificial recharge may return fresh water pressure to halt saltwater intrusion.
Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.

For hydroelectric power uses, a surge tank is an additional storage space or reservoir fitted between the main storage reservoir and the powerhouse (as close to the powerhouse as possible). Surge tanks are usually provided in high or medium- head plants when there is a considerable distance between the water source and the power unit ...
The compression of the gel in closed system lead to change in salt concentration, whereas the compression in open system, while the gel is exchanging ions with bulk, lead to the change in the number of ions. The consequence of the compression and swelling in open and closed system conditions mimics the reverse Carnot Cycle of refrigerator machine.
