    (2) Oxygenated Treatment (OT) (3) Combine Water Treatment (CWT) are adopted to minimize corrosion. Thus it is very important and critical to monitor and control Dissolved oxygen and pH values in Feed water systems. The typical points in steam circuit where dissolved oxygen monitoring is required are . Condenser outlet, L.P. heaters, Economizer ...

  3. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    Chemical water analysis is carried out on water used in industrial processes, on waste-water stream, on rivers and stream, on rainfall and on the sea. [1] In all cases the results of the analysis provides information that can be used to make decisions or to provide re-assurance that conditions are as expected.

  4. Wastewater quality indicators - Wikipedia

    en.wikipedia.org/wiki/Wastewater_quality_indicators

    Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal, treatment or reuse. The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal ...

  5. Sulfate attack in concrete and mortar - Wikipedia

    en.wikipedia.org/wiki/Sulfate_attack_in_concrete...

    In masonry, sulfates produced by the oxidation of pyrite in clay materials can be present in bricks. They are gradually released over a long period of time, causing sulfate attack of mortar, especially where moisture movement concentrates the sulfates. [4] Seawater: sulfate is the second anion present in seawater after chloride.

  6. Sulfur water - Wikipedia

    en.wikipedia.org/wiki/Sulfur_water

    Sulfur water is made out of dissolved minerals that contain sulfate. These include baryte (BaSO 4), epsomite (MgSO 4 7H 2 O) and gypsum (CaSO 4 2H 2 0). [1] It is reported that a notable change in taste to the water is found dependent upon the type of sulfate affecting the water.

  7. Water treatment - Wikipedia

    en.wikipedia.org/wiki/Water_treatment

    Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.

  8. Organosulfate - Wikipedia

    en.wikipedia.org/wiki/Organosulfate

    The primary disposal of alkyl sulfate from used commercial products is wastewater. The concentration of alkylsulfates in effluent from waste water treatment plants (WWTP) has been measured at 10 micrograms per litre (5.8 × 10 −9 oz/cu in) and lower. Alkyl sulfates biodegrade easily, even starting likely before reaching the WWTP.

  9. Chemical phosphorus removal - Wikipedia

    en.wikipedia.org/wiki/Chemical_phosphorus_removal

    Alum treatment begins with the addition of aluminum sulfate salt to a water body. Once added, the salt dissolves and dissociates, introducing Al(III) ions to the water. The aluminum ions participate in a series of hydrolysis reactions, forming different aluminum species across pH ranges. As more aluminum sulfate is added, water pH decreases.
