  2. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Bottled mineral water usually contains higher TDS levels than tap water. 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).

  3. Ultrapure water - Wikipedia

    en.wikipedia.org/wiki/Ultrapure_water

    Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including organic and inorganic compounds, dissolved and particulate matter, and ...

  4. Total suspended solids - Wikipedia

    en.wikipedia.org/wiki/Total_suspended_solids

    TSS of a water or wastewater sample is determined by pouring a carefully measured volume of water (typically one litre; but less if the particulate density is high, or as much as two or three litres for very clean water) through a pre-weighed filter of a specified pore size, then weighing the filter again after the drying process that removes all water on the filter.

    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. Conductivity (electrolytic) - Wikipedia

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

    The electrolytic conductivity of ultra-high purity water increases as a function of temperature (T) due to the higher dissociation of H 2 O in H + and OH − with T. In many cases, conductivity is linked directly to the total dissolved solids (TDS). High-quality deionized water has a conductivity of
