    The clarified water is then fed through a high-pressure piston pump into a series of RO vessels. 90.00–99.98% of the raw water's total dissolved solids are removed and military standards require that the result have no more than 1000–1500 parts per million by measure of electrical conductivity.

  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.

  4. 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.

  5. 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 ...

  6. Osmotic pressure - Wikipedia

    en.wikipedia.org/wiki/Osmotic_pressure

    Osmotic pressure is the basis of filtering ("reverse osmosis"), a process commonly used in water purification. The water to be purified is placed in a chamber and put under an amount of pressure greater than the osmotic pressure exerted by the water and the solutes dissolved in it.

  7. Pressure tank - Wikipedia

    en.wikipedia.org/wiki/Pressure_tank

    The diaphragm or bladder may itself exert a pressure on the water, but it is usually small and will be neglected in the following discussion. Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V.
