  2. Ammonia solution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_solution

    Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −

  3. Turbomolecular pump - Wikipedia

    en.wikipedia.org/wiki/Turbomolecular_pump

    Most turbomolecular pumps employ multiple stages, each consisting of a quickly rotating rotor blade and stationary stator blade pair. The system is an axial compressor that puts energy into the gas, rather than a turbine, which takes energy out of a moving fluid to create rotary power, thus "turbomolecular pump" is a misnomer.

  4. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    Where it is necessary to raise water to a height above that to which a suction or lift pump will operate effectively (about 7 metres), or to raise the pressure so that it will exit a nozzle with a strong force, such as through a fire hose, a force pump may be used. As with a suction pump, in its manual form it relies on an operator to pump a ...

    en.wikipedia.org/wiki/Periodic_Videos

    Periodic Videos (also known as The Periodic Table of Videos) is a video project and YouTube channel on chemistry. It consists of a series of videos about chemical elements and the periodic table , with additional videos on other topics in chemistry and related fields.

  6. Rotating biological contactor - Wikipedia

    en.wikipedia.org/wiki/Rotating_biological_contactor

    Schematic diagram of a typical rotating biological contactor (RBC). The treated effluent clarifier/settler is not included in the diagram. A rotating biological contactor or RBC is a biological fixed-film treatment process used in the secondary treatment of wastewater following primary treatment.

  7. Flash evaporation - Wikipedia

    en.wikipedia.org/wiki/Flash_evaporation

    If the saturated liquid is a single-component liquid (for example, propane or liquid ammonia), a part of the liquid immediately "flashes" into vapor. Both the vapor and the residual liquid are cooled to the saturation temperature of the liquid at the reduced pressure.

  8. Condensate pump - Wikipedia

    en.wikipedia.org/wiki/Condensate_pump

    This pump and possibly many more around the plant returns this hot water back to a make-up tank closer to the boiler, where it can be reclaimed, chemically treated, and reused, in the boiler, consequently it can sometimes be referred to as a condensate return pump.

  9. Pulser pump - Wikipedia

    en.wikipedia.org/wiki/Pulser_Pump

    A pulser pump makes use of water that flows through pipes and an air chamber from an upper reservoir to a lower reservoir. The intake is a trompe, which uses water flow to pump air to a separation chamber; air trapped in the chamber then drives an airlift pump. The top of the pipe that connects the upper reservoir to the air chamber is ...
