Brackish Water Reverse Osmosis typically has a TDS between 1,000 and 15,000 PPM or mg/L. In brackish water there are smaller levels of dissolved minerals and salts then say sea water. Typically impurities such as these make for water that is very hard to use in many applications. Water that is too salty to be labeled as potable water, but not salty enough to be labeled as seawater falls into the category of brackish water. When talking in regards to well water generally fresh groundwater can mix with brine water and produce brackish water. This brackish well water if not treated correctly can damage homes, agriculture and many other applications.
Water Treatment Specialists manufacture and specialize in tap water reverse osmosis systems from 500 to 1,000,000+ gallons per day.
