  2. Steam and water analysis system - Wikipedia

    en.wikipedia.org/wiki/Steam_and_water_analysis...

    Steam and water analysis system (SWAS) [1] is a system dedicated to the analysis of steam or water.In power stations, it is usually used to analyze boiler steam and water to ensure the water used to generate electricity is clean from impurities which can cause corrosion to any metallic surface, such as in boiler and turbine.

  3. Boiler water - Wikipedia

    en.wikipedia.org/wiki/Boiler_water

    Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam. The term may also be applied to raw water intended for use in boilers, treated boiler feedwater , steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.

  4. Phosphate test - Wikipedia

    The next step is to add dilute stannous chloride reagent, which has been freshly prepared from concentrated stannous chloride reagent and distilled water, to the mixture in the tube. This will produce a blue colour (due to the formation of molybdenum blue ) and the depth of the blue colour indicates the amount of phosphate in the boiler water.

  5. Boiler feedwater - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater

    Boiler water must be treated in order to be proficient in producing steam. 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 ...

  6. Industrial water treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_water_treatment

    Two of the main processes of industrial water treatment are boiler water treatment and cooling water treatment. A large amount of proper water treatment can lead to the reaction of solids and bacteria within pipe work and boiler housing. Steam boilers can suffer from scale or corrosion when left untreated. Scale deposits can lead to weak and ...

  7. Industrial wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_wastewater...

    This might include pure chemical synthesis or boiler feed water. Also, some water treatment processes produce organic and mineral sludges from filtration and sedimentation which require treatment. Ion exchange using natural or synthetic resins removes calcium , magnesium and carbonate ions from water, typically replacing them with sodium ...

  8. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    To ensure consistency and repeatability, the methods use in the chemical analysis of water samples are often agreed and published at a national or state level. By convention these are often referred to as "Blue book". [4] [5] Certain analyses are performed in-field (e.g. pH, specific conductance) while others involve sampling and laboratory ...

  9. Wastewater quality indicators - Wikipedia

    en.wikipedia.org/wiki/Wastewater_quality_indicators

    Oxidizable chemicals (such as reducing chemicals) introduced into a natural water will similarly initiate chemical reactions (such as shown above). Those chemical reactions create what is measured in the laboratory as COD. Both the BOD and COD tests are a measure of the relative oxygen-depletion effect of a waste contaminant.
