Contaminants in water

Contaminants in water is an article on Bromine (bromide), Chloride, and Sulfate. But remember that we can correct virtually any contaminants in water you drink. Such as coli, coliform, arsenic, nitrates, tannins, PFAS, chemicals and heavy metals. Have a problem that is not listed here? Give us a call. Because we can fix it. These harmful contaminants in water can be removed with reverse osmosis
Bromine is found in sea water. And exists as the bromide ion at a level of about 65 mg/L. Also, Bromine has been used in swimming pools. And in cooling towers for disinfection. However, use in drinking water is not recommended. And Ethylene Bromide is used as an anti-knock additive in gasoline. And methyl bromide is a soil fumigant. Bromine is extremely reactive and corrosive. And will produce irritation and burning to exposed tissues. Over 0.05 mg/L in fresh water may indicate the presence of industrial wastes. That is possibly from the use of pesticides of biocides containing bromine. And bromide is extensively used in the pharmaceutical industry. Also it occurs normally in blood in the range of 1.5 to 50 mg/L.
Bromide Treatment
Reverse Osmosis will remove 93-96% of the bromide from drinking water. And since bromine is a disinfectant. Also can be removed with Activated Carbon, Ultra Filtration, or Electro Dialysis.
Chloride (C1-1) is one of the major anions found in water. And is generally combined with calcium, magnesium, or sodium. Since almost all chloride salts are highly soluble in water. The chloride content ranges from 10to 100 mg/L. And sea water contains over 30,000 mg/L as NaCl. Also chloride is associated with the corrosion of piping because of the compounds formed with it. For example, magnesium chloride can generate hydrochloric acid when heated. Corrosion rates and the iron dissolved into the water from piping increases. As the sodium chloride content of the water is increased. And the chloride ion is instrumental in breaking down passivating films. Which protect ferrous metals and alloys from corrosion. And is one of the main causes for the pitting corrosion of stainless steel. The SMCL (suggested maximum contaminant level) for chloride is 250 mg/L. Which is due strictly to the objectionable salty taste produced in drinking water.
Chloride Treatment
Reverse Osmosis will remove 90-95% of the chlorides in water. Because of its salt rejection capabilities. And both Electro Dialysis and distillation are two more process which can be used to reduce the chloride content of water. And a strong base anion exchanger. Which is the later portion of a two-column deionizer. Also does an excellent job at removing chlorides for industrial applications.
Sulfate (SO4) occurs in almost all natural water. Most sulfate compounds originate from the oxidation of sulfite ores, the presence of shale, and the existence of industrial wastes. Sulfate is one of the major dissolved constituents in rain. High concentrations of sulfate in drinking water causes a laxative effect when combined with calcium and magnesium, the two most common components of hardness. Bacteria that attack and reduce sulfates, causes hydrogen sulfide gas H2S to form. Sulfate has a suggested level of 250 mg/L in the Secondary Drinking Water Standards published by the US EPA.
Sulfate Treatment
Reverse Osmosis will reduce the sulfate content by 97-98%. Sulfates can also be reduced with a strong base anion exchanger, which is normally the last half of a two-column deionizer.
