  2. Reverse osmosis - Wikipedia

    en.wikipedia.org/wiki/Reverse_osmosis

    Household RO units use a lot of water because they have low back pressure. Household RO water purifiers typically produce one liter of usable water and 3-25 liters of wastewater. [34] The remainder is discharged, usually into the drain. Because wastewater carries the rejected contaminants, recovering this water is not practical for household ...

  3. Reverse osmosis plant - Wikipedia

    en.wikipedia.org/wiki/Reverse_osmosis_plant

    Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination , wastewater treatment , concentration of contaminants, and the reclamation of dissolved minerals. [ 1 ]

  4. Electrodeionization - Wikipedia

    en.wikipedia.org/wiki/Electrodeionization

    Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically ...

  5. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Reverse osmosis involves mechanical pressure applied to force water through a semi-permeable membrane. Contaminants are left on the other side of the membrane. Reverse osmosis is theoretically the most thorough method of large scale water purification available, although perfect semi-permeable membranes are difficult to create.

  6. Dailymotion - Wikipedia

    en.wikipedia.org/wiki/Dailymotion

    In September 2020, Dailymotion partnered with Mi Video, the global video app developed by Xiaomi. [18] The partnership will help Mi Video to increase its engagement with its audience and continue its growth momentum. Access to Dailymotion's global and regional music, entertainment, sports and news catalogues will be provided to Mi Video users. [19]

  7. Purified water - Wikipedia

    en.wikipedia.org/wiki/Purified_water

    Distilled water was, formerly, the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization.

  8. Water filter - Wikipedia

    en.wikipedia.org/wiki/Water_filter

    A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation , accessible drinking water , public and private aquariums , and the safe use of ponds and swimming ...

  9. Industrial water treatment - Wikipedia

    en.wikipedia.org/wiki/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 the challenges of industrial water treatment.
