Water Purification System Works primary aperture fiber filter column 5um, so it can block smaller particles, thus ensuring clean water and extend the service life of downstream components. Because in the water column into the activated carbon column and RO, we need a certain pressure, which we call osmotic pressure, where the fiber column outlet using the booster pump to allow pressurized water to enter the post-activated carbon column.
Activated carbon is a widely used adsorbent, the following table illustrate its superior performance:

Activated carbon can adsorb a considerable number of inorganic and organic, but it‘s adsorption capacity for different substances the difference is there, the following listed in the table with easy and difficult to adsorption of organic matter.
Easy adsorption
   Difficult adsorption
  
1. Aromatic solvents, benzene, toluene, nitrobenzene
   1. Alcohol
  
2. Chlorinated hydrocarbons such as incense, PCBs, chlorobenzene
   2. Paper molecule ketone, phenolic
  
3. Phenol and chlorophenol
   3. Sugar, starch
  
4. Pesticide, DDT, BHC and other
   4, a high molecular weight organic or colloidal organic matter
  
5. CC14
   5, low molecular weight of the fats
  
6. Polymeric dyes, gasoline, amine
   
  
In short, the activated carbon played a significant role in four areas:

To reduce the oxidation of water demand
Avoid organic material into, resulting in destruction of ion-exchange bed
To remove residual chlorine in water
To remove the water three halides (THM), especially its adsorption of chlorine is almost 100%, while the residual chlorine in the water right behind the devastating RO membranes, RO membranes can cause failure.
Check out from the activated carbon adsorption of water re-entering the RO reverse osmosis filters. Reverse osmosis principle is that the University of Florida by the United States Reid, who proposed in 1953, but developed into a practical technology in the last few years. And the membrane material from the early asymmetric cellulose acetate film to today‘s cross-linked aromatic polyamide composite
Membrane. Its principle is shown below
Reverse osmosis membrane pore size is generally between 10A to 100A, so that it can remove more than 95% of the ionic state of impurities, Table 1 shows the RO filter to remove the ability of a variety of substances.
