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. 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 ...

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 water ...

5. Conductivity (electrolytic) - Wikipedia

   en.wikipedia.org/wiki/Conductivity_(electrolytic)

   For example, conductivity measurements are used to monitor quality in public water supplies, in hospitals, in boiler water and industries that depend on water quality such as brewing. This type of measurement is not ion-specific; it can sometimes be used to determine the amount of total dissolved solids (TDS) if the composition of the solution ...

6. Analysis of water chemistry - Wikipedia

   en.wikipedia.org/wiki/Analysis_of_water_chemistry

   Nephelometers are used to measure solids concentrations as turbidity. These methods are generally robust and well tried and inexpensive, giving a reasonable degree of accuracy at modest sensitivity. Electro chemistry including pH, conductivity and dissolved oxygen using oxygen electrode. These methods yield accurate and precise results using ...

7. Water quality - Wikipedia

   en.wikipedia.org/wiki/Water_quality

   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)

8. Water clarity - Wikipedia

   en.wikipedia.org/wiki/Water_clarity

   Metrics used to measure water clarity. Water clarity is measured using multiple techniques. These measurements include: Secchi depth, light attenuation, turbidity, beam attenuation, absorption by colored dissolved organic matter, the concentration of chlorophyll-a pigment, and the concentration of total suspended solids.

9. Wastewater quality indicators - Wikipedia

   en.wikipedia.org/wiki/Wastewater_quality_indicators

   The mass of dried solids remaining on the filter is called total suspended solids (TSS) or nonfilterable residue. Settleable solids are measured as the visible volume accumulated at the bottom of an Imhoff cone after water has settled for one hour. [2]: 89–98 Turbidity is a measure of the light scattering ability of suspended matter in the water.
