The Total Dissolved Solids or TDS of reverse osmosis water is often a measure of the dissolved salt content. For seawater the TDS is generally between 33,000 mg/L and 40,000 mg/L. The World Health Or [..]

Dissolved mineral nutrients present in water as measured in parts per million (ppm).

An aggregate of carbonates, bicarbonates, chlorides, sulfates, phosphates, nitrates, etc., of calcium, magnesium, manganese, sodium, potassium, and other cations which form salts. High TDS concentrations exert varying degrees of osmotic pressures and often become lethal to the biological inhabitants of an aquatic environment. The common and synonym [..]

The concentration of dissolved solids in a wastewater or effluent, ie the residue after evaporation and drying, expressed in milligrams per litre of sample.

Total dissolved solids (TDS) is a water-quality related term which refers to the total content of all organic and/or inorganic solids which are dissolved (filterable) within water. TDS is expressed in units of milligrams (mg) per unit volume of water (e.g. mg/L). See also Total Suspended Solids (TDS).

A measure of the salinity of water, sometimes referred to as total dissolved salts, usually expressed in milligrams per litre (mg/L). An alternative measure is total soluble salts (TSS).

amount of inorganic materials such as minerals, salts, metals, cations, or anions dissolved in water

All material that passes the standard glass river filter; now called total filtrable residue. Term is used to reflect salinity.

All material that passes the standard glass river filter; now called total filtrable residue. Term is used to reflect salinity.

The total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water.

The dry weight of all material in solution in a water sample. 

The total amount of solid material dissolved in one liter of water.

is a water quality parameter defining the concentration of dissolved organic and inorganic chemicals in water. After suspended solids are filtered from water and water is evaporated, dissolved solids are the remaining residue. Dissolved solids commonly found in Nebraska water are calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride [..]

Is determined by filtering a measured volume of sample through a standard glass fiber filter. The filtrate (i.e., filtered liquid) is then evaporated to dryness at a constant temperature of 180 C. High total dissolved solids may effect the aesthetic quality of the water, interfere with washing clothes and corroding plumbing fixtures. For aesthetic [..]

All of the dissolved solids in a water. TDS is measured on a sample of water that has passed through a very fine mesh filter to remove suspended solids. The water passing through the filter is evapora [..]

The total weight of the solids dissolved in water. Treatment Technique (TT)

A quantitative measure of the residual minerals dissolved in water that remain after evaporation of a solution. Usually expressed in milligrams per liter (mg/l) or in parts per million (ppm). See al [..]

The weight of solids per unit volume of water which are in true solution. This is usually determined by evaporating a measured volume of filtered water and measuring the residue weight. TDS is expressed as ppm per unit volume of water.

The measure of the combined content of all inorganic and organic substances. The principle use of TDS is in the application of water quality for streams, rivers, and lakes to indicate the presence of [..]

The total amount of particulate and dissolved solids in a solution, usually measured in mg/l. The ionic components of the TDS may also be measured as conductivity or resistivity.

The total amount of solids, such as minerals, salts, or metals that are dissolved in a given volume of water.

a measure of the inorganic salts (and organic compounds) dissolved in water[3]

Concentration of total dissolved solids (TDS) in groundwater expressed in milligrams per litre (mg/L), is found by evaporating a measured volume of filtered sample to dryness and weighing this dry solid residue.
