Total Dissolved Solids refer to any minerals such as sand, heavy metals, cations and anions dissolved in water. This includes anything present in water other than the pure water molecules and suspended solids. Suspended Solids are any particles that are neither dissolved nor settled in the water such as waste pulp. Some dissolved solids come from organic sources such as silt, plankton and industrial waste and sewage. They can also come from inorganic materials such as Arsenic, Iron, Manganese, Hydrogen Sulfide including Uranium and Radium. Municipal water always pick up metals such as Lead or Copper as they travel through pipes which is used to distribute water to consumers.These metals (ions) are associated with staining, taste, precipitation. With respect to trace metals, they mostly contribute to health risk.
To keep in mind that water from desalination or Reverse Osmosis with a very low TDS concentration is corrosive and corrosive water always leak toxic metals such as Iron, Manganese, Copper and Lead from household plumbing. This also means not only well water and surface water but also city water bring trace metals which could pose a health risk.
Using Crystolite™ media in a pressure vessel to provide a microfiltration effect, the Crystolite™ media allows the water to flow through the top distributor on the top of media layer, when suspended solids are held on the highest surface area of the media allows only clean water to flow through the Crystolite™ media. As a result, Crystolite™ can be used to filter down 0.5 microns without clogging. It allows all suspended solids to accumulate on the surface of the Crystolite™ media and are easily backwashed to drain. The system can be designed either manual backwash or by using automatic backwash cycle, the backwash cycle is maximum 10 minutes which uses 80% less water then any traditional anthracite or multimedia filters, it is because 90% of the solids are captured on surface and not inside of the Crystolite™ media-bed. This results if the High-tech filtration that can filter solids and particles down to submicron levels at 10 to 15 times the flow rate of all traditional filters. Backwash water reduction is up to 80%.
