Reverse osmosis (RO) and Nano-filtration (NF) are physical separation technologies used to remove contaminants from liquids. Both RO and NF require pressure to function.Both are used in place of conventional treatment technologies. Find out how they differ and how they're similar to make the best choice for your water purification.
Freshwater is full of contamination and pollutants from natural and manmade sources. What causes these pollutants in freshwater, how do metals like arsenic, cadmium, chromium, copper, nickel, lead and mercury get into freshwater and how toxic are there to humans?
Ever wonder what is the size of water contaminants and particles to figure out what water filters and water purification systems are adequate enough to purify your drinking water? Here's a partial list of water contamination particles and particle sizes in microns.
Comparison between Micro-filtration, ultra-filtration, nano-filtration, distillation, UV, ozonation, deionization and Reverse Osmosis (RO)...what is the difference between various water (and other fluids) purification and filtration methods in the removal of contaminants, and which filtration or purification process is best for residential (home), commercial (office) and industrial use.
