  3. Recirculating aquaculture system - Wikipedia

    en.wikipedia.org/wiki/Recirculating_aquaculture...

    Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [2]

    en.wikipedia.org/wiki/Raceway_(aquaculture)

    A raceway is most often a rectangular canal with a water current flowing from a supply end to an exit end. The length to width ratio is important in raceways. To prevent the fish stock from swimming in circular movements, which would cause debris to build up in the centre, a length to width ratio of at least six to one is recommended.

    Hippocrates believed that water had to be clean and pure. Rainwater was the best water, but had to be boiled and strained before drinking to get rid of the "bad smell" and to avoid hoarseness of the voice.

    Sources where drinking water is commonly obtained include springs, hyporheic zones and aquifers (groundwater), from rainwater harvesting, surface water (from rivers, streams, glaciers), or desalinated seawater. For these water sources to be consumed safely, they must receive adequate water treatment and meet drinking water quality standards.

    en.wikipedia.org/wiki/Water_chlorination

    Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and other microbes in water. In particular, chlorination is used to prevent the spread of waterborne diseases such as cholera, dysentery, and typhoid. [1] [2] [3]
