Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination , wastewater treatment , concentration of contaminants, and the reclamation of dissolved minerals.

A switching or variable-voltage system (also known as a "wavemaker") is commonly used in reef aquaria to more closely simulate the movement of ocean water. [ 1 ] Water circulation is vital to proper biological filtration of most saltwater aquaria (particularly those using the Berlin Method ), and is useful in freshwater aquaria for allowing ...
These filters are usually small, portable and lightweight (1–2 lb (0.45–0.91 kg) or less). These usually filter water by working a mechanical hand pump, although some use a siphon drip system to force water through, while others are built into water bottles. Dirty water is pumped via a screen-filtered flexible silicon tube through a ...
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).
The ideal water potential between fresh water (right) and sea water (left) corresponds to a hydraulic head of 270 metres. Pressure retarded osmosis (PRO) is a technique to separate a solvent (for example, fresh water) from a solution that is more concentrated (e.g. sea water) and also pressurized.
