  2. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Total dissolved solids ( TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular ( colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.

  3. Fresh water - Wikipedia

    en.wikipedia.org/wiki/Fresh_water

    Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non-salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and ...

  4. Total suspended solids - Wikipedia

    en.wikipedia.org/wiki/Total_suspended_solids

    Total suspended solids. Total suspended solids ( TSS) is the dry-weight of suspended particles, that are not dissolved, in a sample of water that can be trapped by a filter that is analyzed using a filtration apparatus known as sintered glass crucible. TSS is a water quality parameter used to assess the quality of a specimen of any type of ...

    en.wikipedia.org/wiki/Wastewater_quality_indicators

    Solid material in wastewater may be dissolved, suspended, or settled. Total dissolved solids or TDS (sometimes called filterable residue) is measured as the mass of residue remaining when a measured volume of filtered water is evaporated. The mass of dried solids remaining on the filter is called total suspended solids (TSS) or nonfilterable ...

    The more calcium and magnesium ions that are dissolved in water, the harder it is said to be; water with few dissolved calcium and magnesium ions is described as being soft. [2] The U.S. Food and Drug Administration classifies mineral water as water containing at least 250 parts per million total dissolved solids (TDS), originating from a ...

  8. Brix - Wikipedia

    en.wikipedia.org/wiki/Brix

    Brix. Degrees Brix (symbol °Bx) is a measure of the dissolved solids in a liquid, and is commonly used to measure dissolved sugar content of an aqueous solution. [1] One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. If the solution contains dissolved solids other ...

    An electrical conductivity meter is used to measure total dissolved solids. The following is a list of indicators often measured by situational category: Alkalinity; Color of water; pH; Taste and odor (geosmin, 2-Methylisoborneol (MIB), etc.) Dissolved metals and salts (sodium, chloride, potassium, calcium, manganese, magnesium)
