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. Waste stabilization pond - Wikipedia

   en.wikipedia.org/wiki/Waste_stabilization_pond

   Anaerobic ponds allow solids to settle down at the bottom as sludge. This settling removes a portion of the particulate organic material. A large fraction of the settled solids will accumulate close to the point where wastewater enters the pond. Therefore, anaerobic ponds must be designed to be far deeper than either aerobic or facultative ponds.

4. 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 ...

5. Settling basin - Wikipedia

   en.wikipedia.org/wiki/Settling_basin

   A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater. The basins are used to control water pollution in diverse industries such as agriculture, [1] aquaculture, [2] and mining. [3] [4] Turbidity is an optical property of water caused by ...

6. 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)

7. Brine mining - Wikipedia

   en.wikipedia.org/wiki/Brine_mining

   The concentration of dissolved solids in deep connate water varies from much less than seawater to ten times the total dissolved solids of seawater. In general, total dissolved solids (TDS) concentrations increase with depth. Most deep groundwaters classified as brines (having total dissolved solids equal to or greater than that of seawater ...
