Municipal tap water is the water supplied by the local municipality for domestic, commercial and industrial applications. In a few countries, municipal water is drinkable, however in large parts of the world, municipal water quality is unfit for drinking and needs to be further purified before consumption.
Typical contaminants can be heavy metals and microbial matter, which come due to the poor maintenance of water pipes, leakage points and other factors. Even with regulated treatment, contamination may still be found in tap water and can pose health risks, such as gastrointestinal illness, neurological disorders, and reproductive problems.
Why choose SWT-CDI?
SWT-CDI (Capacitive Deionization) technology extracts ions of all types from feed water, including sodium, calcium, magnesium, chloride and toxic ions such as arsenate and fluoride. Unlike reverse osmosis process which required high pressure and expensive piping, SWT-CDI applies low voltage across the CDI electrode to control the ion content of the treated water which incurred low operating cost.
SWT has been evaluating a commercial pilot in this sector where the municipal water is further purified prior to packaging them into locally bottled drinking water. The treated water is able to meet the drinking water standards.
