Water Treatment : Total Dissolved Solids
What are Total Dissolved Solids?
The expression, "total
dissolved solids" (TDS), refers to the total amount of all inorganic and
organic substances – including minerals, salts, metals, cations or
anions – that are dispersed within a volume of water. TDS concentrations
are equal to the sum of positively charged ions (cations) and negatively
charged ions (anions) in the water. Sources for TDS include agricultural
run-off, urban run-off, industrial wastewater, sewage, and natural
sources such as leaves, silt, plankton, and rocks. Piping or plumbing
may also release metals into the water.
are Drinking Water Effects of Total Dissolved Solids?
While TDS is not considered a primary
pollutant, high TDS levels typically indicate hard water and may lead to
scale buildup in pipes, reduced efficiency of water filters, hot
water heaters, etc., and aesthetic problems such as a bitter or salty
taste. TDS is the sum of the mineral salts in water and if too high can
result in objectionable taste, cloudy ice, interference with the flavor
of foods and beverages and scale left behind in cookware. Generally
speaking, the lower the TDS the more acceptable the drinking water.
Reverse Osmosis (RO) process has proven itself as the most practical and
cost effective method of correcting problems caused by high TDS. High
TDS content in water will exhibit a salty or brackish taste.
The United States
Environmental Protection Agency (EPA) recommends treatment when TDS
concentrations exceed 500 mg/L, or 500 parts per million (ppm). The TDS
concentration is considered a Secondary Drinking Water Standard, which
means that it
is not a health hazard.
However, further testing may be warranted, as water with a high TDS
concentration may indicate elevated levels of ions that do pose a health
concern, such as
aluminum, arsenic, copper, lead, nitrate and others.
How does high TDS Effect Commercial Business
High levels of total dissolved
solids can adversely industrial applications requiring the use of water
such as cooling tower operations; boiler feed water, food and beverage
industries, and electronics manufacturers. High levels of chloride and
sulfate will accelerate corrosion of metals.
We have treated residential and
commercial total dissolved solids from as little as 750ppm to brackish
10,000ppm to high 35,000ppm sea water sources.
