  2. 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.

  3. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    This contaminated water can be disposed of, along with the sludge from the sedimentation basin, or it can be recycled by mixing with the raw water entering the plant although this is often considered poor practice since it re-introduces an elevated concentration of bacteria into the raw water. Some water treatment plants employ pressure filters.

  4. Zero liquid discharge - Wikipedia

    en.wikipedia.org/wiki/Zero_Liquid_Discharge

    Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable for reuse (e.g., irrigation). ZLD systems employ wastewater treatment technologies and desalination to purify and recycle virtually all wastewater received. [1] [2]

  5. Organisms involved in water purification - Wikipedia

    Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [ 5 ] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.

    AguaClara Cornell is an engineering based project team within Cornell University's College of Engineering [2] that designs sustainable water treatment plants using open source technology. The program's mission is to uphold and protect “the fundamental human right to access safe drinking water.

  7. Wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Wastewater_treatment

    Sewage treatment plant (a type of wastewater treatment plant) in La Crosse, Wisconsin. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment.

  9. Industrial water treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_water_treatment

    Advancements in water treatment technology have affected all areas of industrial water treatment. Although mechanical filtration, such as reverse osmosis , is widely employed to filter contaminants, other technologies including the use of ozone generators, wastewater evaporation, electrodeionization and bioremediation are also able to address ...
