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. Wastewater quality indicators - Wikipedia

   en.wikipedia.org/wiki/Wastewater_quality_indicators

   Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal, treatment or reuse. The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal ...

4. Total suspended solids - Wikipedia

   en.wikipedia.org/wiki/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 or water body, ocean ...

5. Turbidity - Wikipedia

   en.wikipedia.org/wiki/Turbidity

   v. t. e. Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of both water clarity and water quality . Fluids can contain suspended solid matter consisting of particles of many ...

6. Water quality - Wikipedia

   en.wikipedia.org/wiki/Water_quality

   The key basic water quality parameters that need to be addressed in an emergency are bacteriological indicators of fecal contamination, free chlorine residual, pH, turbidity and possibly conductivity/total dissolved solids. There are many decontamination methods.

7. Analysis of water chemistry - Wikipedia

   en.wikipedia.org/wiki/Analysis_of_water_chemistry

   Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters . Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry.
