  2. Oxygenated treatment - Wikipedia

    en.wikipedia.org/wiki/Oxygenated_treatment

    With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30 and 50 ppb. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers.

  3. Fine bubble diffusers - Wikipedia

    en.wikipedia.org/wiki/Fine_bubble_diffusers

    The subject of bubble size is important because the aeration system in a wastewater or sewage treatment plant consumes an average of 50 to 70 percent of the energy of the entire plant. [3] Increasing the oxygen transfer efficiency decreases the power the plant requires to provide the same quality of effluent water. Furthermore, fine bubble ...

  4. Deaerator - Wikipedia

    en.wikipedia.org/wiki/Deaerator

    The treated water falls into a storage tank below the deaerator. [20] [3] Oxygen scavenging chemicals are very often added to the deaerated boiler feedwater to remove any last traces of oxygen that were not removed by the deaerator. The type of chemical added depends on whether the location uses a volatile or non-volatile water treatment program.

  5. Recirculating aquaculture system - Wikipedia

    en.wikipedia.org/wiki/Recirculating_aquaculture...

    Removing solids reduces bacteria growth, oxygen demand, and the proliferation of disease. The simplest method for removing solids is the creation of settling basin where the relative velocity of the water is slow and particles can settle at the bottom of the tank where they are either flushed out or vacuumed out manually using a siphon.

  6. Drum pump - Wikipedia

    en.wikipedia.org/wiki/Drum_pump

    Drum pump, barrel pump, and transfer pump refer to pumps that are used to empty barrels, tanks, IBCs and drums. [1] Many liquids used on manufacturing and processing plants are delivered in 100 or 200 litre barrels and are too heavy to tip to empty the liquids inside. Drum pumps range from simple siphon based devices to sophisticated highly ...

  7. Sequencing batch reactor - Wikipedia

    en.wikipedia.org/wiki/Sequencing_batch_reactor

    The tanks have a “flow through” system, with raw wastewater (influent) coming in at one end and treated water (effluent) flowing out the other. In systems with multiple tanks, while one tank is in settle/decant mode the other is aerating and filling. In some systems, tanks contain a section known as the bio-selector, which consists of a ...

  8. Diffuser (sewage) - Wikipedia

    en.wikipedia.org/wiki/Diffuser_(sewage)

    An air diffuser or membrane diffuser is an aeration device typically in the shape of a disc, tube or plate, which is used to transfer air and with that oxygen into the sewage or industrial wastewater. Oxygen is required by microorganisms/bacteria residents in the water to break down the pollutants.

  9. Boiler feedwater - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater

    Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down.
