This article will show you 4 mainly-used filtration technologies in water purification treatment. What the 4 water purification methods could remove are listed below paragraphs.
Micro Filtration
Water purification accuracy of micro filtration is 0.1 to 50 microns. PP sediment filter and ceramic cartridge filters belong to micro filtration water purification to be used for pre water purification. It can filter sand, rust and other large particles but waterborne bacteria, virus, organics and heavy metals.
Ultra Filtration
With a 0.001 to 0.1 micron accuracy, ultra filtration water purification filters works well in reduction of rust, sand, colloids, bacteria, virus, macromolecular organics and other harmful substances. Meanwhile, this water purification technology can keep some beneficial mineral elements during the whole purification.
Nano Filtration
It has filtration accuracy between Ultra Filtration and Reverse Osmosis water purification technologies. Nano filtration is a Membrane Separation Water Purification Technology which usually be used for industrial pure water filtration and purification.
Reverse Osmosis Filtration
0.0001 micron water purification accuracy can remove nearly all bad and good substances in water. Reverse osmosis water purification technology is commonly-used for pure potable water, industrial and medical ultrapure water.
