  2. Diatomaceous earth filtration - Wikipedia

    en.wikipedia.org/wiki/Diatomaceous_earth_filtration

    The process of D.E. filtration is composed of three main stages: pre-coating, body feed, and cleaning. [ 1 ] Due to the precision of diatomaceous earth filtration; being able to capture dangerous and microscopic particles while maintaining efficiency has allowed D.E. filters to be a highly popularized choice for aquariums , wastewater treatment ...

  3. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    The solution travels to a tank that separates the hydrogen gas based on its low density. [1] Only water and sodium chloride are used. The simplified chemical reaction is: NaCl + H 2 O + energy → NaOCl + H 2 [citation needed] That is, energy is added to sodium chloride (table salt) in water, producing sodium hypochlorite and hydrogen gas.

  4. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use. This problem is avoided by the use of sodium hypochlorite, which is a relatively inexpensive solution used in household bleach that releases free chlorine when dissolved in water ...

    Two distinct and separate methods are employed in the sanitation of a swimming pool. The filtration system removes organic waste on a daily basis by using the sieve baskets inside the skimmer and circulation pump and the sand unit with a backwash facility for easy removal of organic waste from the water circulation.

  8. Ringer's solution - Wikipedia

    en.wikipedia.org/wiki/Ringer's_solution

    Ringer's solution is a solution of several salts dissolved in water for the purpose of creating an isotonic solution relative to the body fluids of an animal. Ringer's solution typically contains sodium chloride, potassium chloride, calcium chloride and sodium bicarbonate, with the last used to buffer the pH.
