# Reverse osmosis: Mechanical pressure is applied to an impure solution to force pure water through a semi-permeable membrane.

Reverse osmosis is theoretically the most thorough method of large scale water purification available, although perfect semi-permeable membranes are difficult to create.

Reverse osmosis water purification systems can remove up to 90 % or more of certain inorganic chemicals.

Reverse osmosis can even remove some microbiological contaminants, including Giardia cysts.

Reverse osmosis may not be viable for brine treatment, due to the potential for fouling caused by hardness salts or organic contaminants, or damage to the reverse osmosis membranes from hydrocarbons.

* Reverse osmosis membranes for desalination of water, usually by a Bigmembrane, a 4 " or 8 " diameter element

Reverse osmosis, MSF distillation's main competitor, requires more pretreatment of the seawater and more maintenance, as well as energy in the form of work ( electricity, mechanical power ) as opposed to cheaper low-grade waste heat.

Reverse osmosis is a pressure-driven process that forces the separation of fresh water from other constituents through a semipermeable membrane.

Sirens are sometimes used as part of an integrated warning system that links sirens with other warning media such as the radio and TV Emergency Alert System, NOAA Weather Radio, telephone alerting systems, Reverse 911, Cable Override and wireless alerting systems in the United States and the Emergency Public Warning System in the Canadian province of Alberta.

About 300 samples were seeded from 34 protein types including HIV Reverse Transcriptase Complex ( an enzyme that is a chemical key to the replication of AIDS ) and Factor D ( an important enzyme in human immune systems ).

Sometimes a timeshift ( delay ) is set between two systems, which increases the detection probability of errors induced by external influences ( e. g. Voltage spikes, Ionizing radiation, or In situ Reverse engineering ).

Reverse key indexes have become particularly important in high volume transaction processing systems because they reduce contention for index blocks.

Reverse folds of a corner are typically used to produce feet or birds heads.

Reverse is typically implemented differently ; see the section on Reverse.

Reverse thrust is typically applied immediately after touchdown, often along with spoilers, to improve deceleration early in the landing roll when residual aerodynamic lift and high speed limit the effectiveness of the friction brakes located on the landing gear.

He has pioneered or popularised the use of many techniques in computer graphics, including " adaptive tile refresh " for Commander Keen, raycasting for Hovertank 3-D, Catacomb 3-D, and Wolfenstein 3-D, binary space partitioning which Doom became the first game to use, surface caching which he invented for Quake, Carmack's Reverse ( formally known as z-fail stencil shadows ) which he devised for Doom 3, and MegaTexture technology, first used in Enemy Territory: Quake Wars.

# Reverse the cartridge and use the ramrod to seat the ball and paper envelope onto the powder charge.

Newer military style Reverse Osmosis Water Purification Units ( ROWPU ) are portable, self-contained water treatment plants are becoming more available for public use.

Ford was the first to use the " P R N D L " pattern which separated Reverse from forward ranges by Neutral.

Reverse mathematics makes use of several subsystems of second order arithmetic.

* With rechargeable batteries, a mistake in use or charging may lead to Reverse charging.

However, in another episode, in which he explains to Jerry that wallets are a nuisance and that he should use a money clip, Kramer advises Jerry to " keep the big bills on the outside " and shows Jerry his own money clip as an example, to which Jerry responds, " That's a five " (" The Reverse Peephole ").

Reverse thrust became available due to the development of controllable-pitch propellers, which change the angle of the propeller blades to make efficient use of engine power over a wide range of conditions.

An alternative conception of a Reverse Turing Test is to use the test to determine whether sufficient information is being transmitted between the tester and the subject.

HP calculators are well known for their use of Reverse Polish notation.

Reverse DNS lookups for IPv4 addresses use a reverse IN-ADDR entry in the special domain < tt > in-addr. arpa </ tt >.

Reverse DNS lookups for IPv6 addresses use the special domain.

For example, most calculators use operator precedence parsers to convert from the human-readable infix notation relying on order of operations to a format that is optimized for evaluation such as Reverse Polish notation ( RPN ).

Seeing it too dangerous for anyone else to wield, Chronogel places a curse on Reverse Magic should anyone but himself use it, retreating into a Marudeyona World and sealing himself within a mountain.
