  2. Sidney Loeb - Wikipedia

    en.wikipedia.org/wiki/Sidney_Loeb

    Loeb invented the power generating process pressure retarded osmosis (PRO)--making accessible a rich previously unknown source of green energy, and a method of producing power by a reverse electrodialysis (RED) heat engine, among other inventions in related fields. The production of energy by PRO and RED, among others, is sometimes called ...

  3. Reverse osmosis - Wikipedia

    en.wikipedia.org/wiki/Reverse_osmosis

    Reverse osmosis is a more economical way to concentrate liquids (such as fruit juices) than conventional heat-treatment. Concentration of orange and tomato juice has advantages including a lower operating cost and the ability to avoid heat-treatment, which makes it suitable for heat-sensitive substances such as protein and enzymes .

  4. LifeStraw - Wikipedia

    en.wikipedia.org/wiki/LifeStraw

    Use of LifeStraw. The original LifeStraw is a plastic tube 22 centimetres (8 + 5 ⁄ 8 in) long and 3 centimetres (1 + 1 ⁄ 8 in) in diameter. [8] Water that is drawn up through the straw first passes through hollow fibres that filter water particles down to 0.2 µm across, using only physical filtration methods and no chemicals.

  5. Thin-film composite membrane - Wikipedia

    en.wikipedia.org/wiki/Thin-film_composite_membrane

    TFC membranes for water treatment are commonly classified as nanofiltration (NF) and reverse osmosis (RO) membranes. Both types are typically made out of a thin polyamide layer (<200 nm) deposited on top of a polyethersulfone or polysulfone porous layer (about 50 microns) on top of a non-woven fabric support sheet. The three layer configuration ...

  6. Water filter - Wikipedia

    en.wikipedia.org/wiki/Water_filter

    A new and advanced water purification system using reverse osmosis (RO) technology ensures 99.9% sterilization, effectively removing bacteria, viruses, dissolved salts, and heavy metals. The RO process provides high precision filtration , typically down to 0.0001 microns, ensuring the removal of harmful contaminants while preserving the purity ...

  7. List of desalination plants in Australia - Wikipedia

    en.wikipedia.org/wiki/List_of_desalination...

    As a result of the water supply crisis during the severe 1997–2009 drought State governments around Australia began building desalination plants that purify seawater using reverse osmosis technology. Many of these plants have included in their overall cost the building of renewable energy sources such as wind farms.

  9. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    Single-phase desalination processes include reverse osmosis and membrane distillation, where membranes filter water from contaminants. [15] [17] As of 2014 reverse osmosis (RO) made up about 52% of indirect methods. [21] [22] Pumps push salt water through RO modules at high pressure. [15] [21] RO systems depend on pressure differences. A ...
