  2. Swimming pool sanitation - Wikipedia

    en.wikipedia.org/wiki/Swimming_pool_sanitation

    Alumina, derived from aluminates, filters detrimental materials at the molecular level and can be used to control the delivery rate of desirable metals such as copper. Working through the pool or spa filtration system, mineral sanitizers use combinations of these minerals to inhibit algae growth and eliminate contaminants.

  3. Urine-indicator dye - Wikipedia

    en.wikipedia.org/wiki/Urine-indicator_dye

    Rumours of the origin of urine indicator-dye go back at least as far as 1958, [1] and the story is commonly told to children by parents who do not want them to urinate in the pool. [3] A 1985 biography of Orson Welles describes him using such a dye as part of a prank in 1937.

  4. Algaecide - Wikipedia

    en.wikipedia.org/wiki/Algaecide

    Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protection Agency (EPA) for use as a pesticide and its effectiveness as an algaecide in ponds has produced mixed results during university testing in the United ...

  5. Urea reduction ratio - Wikipedia

    en.wikipedia.org/wiki/Urea_reduction_ratio

    A more accurate relationship between URR and Kt/V can be derived by single-pool, variable volume urea kinetic modeling. A simplified estimating equation also can be used. [2] This gives results that are quite similar to formal urea modeling as long as dialysis treatments of 2–6 hours in duration are given, and Kt/V is between 0.7 and 2.0.

  6. Reuse of human excreta - Wikipedia

    en.wikipedia.org/wiki/Reuse_of_human_excreta

    Urine contains large quantities of nitrogen (mostly as urea), as well as reasonable quantities of dissolved potassium. [15] The nutrient concentrations in urine vary with diet. [16] In particular, the nitrogen content in urine is related to quantity of protein in the diet: A high protein diet results in high urea levels in urine. The nitrogen ...

    The issue has raised concern about a repeat of a supply crunch in 2021 when China's government effectively halted exports of urea - a type of nitrogen used as fertiliser in agriculture as well as ...

  9. Controlled-release fertiliser - Wikipedia

    en.wikipedia.org/wiki/Controlled-release_fertiliser

    Methylene ureas, e.g. methylene diurea, were commercialized in the 1960s and 1970s, having 25% and 60% of the nitrogen as cold-water-insoluble, and unreacted urea nitrogen in the range of 15% to 30%. In the 1960s in the U.S., the Tennessee Valley Authority National Fertilizer Development Center began developing sulfur-coated urea.
