Total dissolved solutes. the concentration of all the elemental ions present in a nutrient solution; electrical conductivity (EC) is a measure of TDS generally expressed as mS (milliSiemens) or mMho (millimhos)
Total Dissolved Solids. 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 may include calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride and silica. Total dissolved solid concentrations depend on the geologic material water passes through in the saturated and unsaturated zone, and the quality of the infiltrating water. High total dissolved solids may effect the aesthetic quality of the water, interfere with washing clothes and corroding plumbing fixtures. For aesthetic reasons, a limit of 500 mg dissolved solids/L is typically recommended for potable water supplies.
Total dissolved solids. Total salt and calcium carbonate concentration in a sample of water. The state recommended Maximum Contaminant Level (MCL) drinking water standard for total dissolved solids is 500 ppm. The upper MCL is 1,000 ppm, and the short-term permitted level is 1,500 ppm.
total dissolved solids. Dissolved and suspended solids in water; material left behind after a water sample is filtered and evaporated. Rainwater will have TDS less than 10ppm; municipal water systems will have TDS less than 500 ppm.
Total Dissolved Solids. Total Dissolved Solids (TDS) - 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.
Total dissolved solids. The sum of all inorganic and organic particulate; TDS is an indicator test usually reserved for wastewater analysis, but is also a measure of the mineral content of bottled water and groundwater.
Total Dissolved Solids. The weight per unit volume of filtered water. The liquid passing the filter are evaporated to dryness. The filter pore diameter and evaporation temperature are frequently specified.
Total Dissolved Solids â€“ a quantity determined by drying the water sample and weighing the residue. In the field, TDS is commonly measured by a conductivity meter; however this measurement is only an approximation.
total dissolved solids A measure of the total amount of dissolved material in the water. It is comprised of the spent or carrier chemicals added every time chemicals are added as well as the hardness, alkalinity, chlorides, sodium, magnesium, calcium, etc. Maximum amount in pools is 2500 ppm. Maximum in spa, 1500 over starting TDS. The only way to effectively lower TDS is to drain part or all of the water and replace it.
total dissolved solids. The concentration of dissolved solids in 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 evaporated and the residue represents the dissolved solids.
TOTAL DISSOLVED SOLIDS. The weight of solids per unit volume of water which are in true solution; usually determined by the evaporation of a measured volume of filtered water and determination of the residue weight. Total Dissolved Solids is a measurement of any minerals or salts in the water. Bicarbonate, Chloride, Sulfate, Calcium, Magnesium, Sodium are the major components of dissolved solids in water. High amounts of these salts provide the major cause of water taste problems. High TDS can cause the water to appear inappropriate to drink, and spotting of glassware, fixtures, or painted surfaces such as automobiles. Also high dissolved solids can diminish the life of home appliances. The EPA has set a maximum contaminant level of 500 ppm.
Total Dissolved Solids - Elevated total dissolved solids can result in your water having a bitter or salty taste; result in incrustations, films, or precipitates on fixtures; corrosion of fixtures, and reduced efficiency of water filters.
total dissolved solids - TDS values are in milligrams per liter (mg/L) or parts per million (ppm). For example, a TDS of 500 mg/L (or 500 ppm) is equal to 0.5 gr/L or ~1/3 teaspoon per gallon of water. See also discussion of TDS in Arizona waters.
TOTAL DISSOLVED SOLIDS. 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 synonymously used term for TDS is "salt".
total dissolved solids. The total weight of the solids that are dissolved in the water, give in ppm per unit volume of water. TDS is determined by filtering a given volume of water (usually through a 0.45 micron filter), evaporating it at a defined temperature (usually 103-105 degrees Celsius), and then weighing the residue. Note: A test measuring the electrical conductivity of the water provides only an estimate of the TDS present, as conductivity is not precisely proportional to the weight of an ion and nonconductive substances cannot be measured by electrical tests.
