5-Stage Reverse Osmosis Drinking Water Filter System 

stage

function

1st

PP fiber filtration wipes off impurities, algae, silt, sediment

2nd

GAC filtration wipes off residual chlorine, THM's, unpleasant smell, pesticides, chemical poisons

3rd

Block carbon remove the heterochrosis,odour,chroline and other materials which are harmful to health.To improve the taste, Will use the micropore of the active carbon filter to holdback the microgranule, micro colloid and micro suspended materials. To make the water which into the RO membrane is suitable so as make the lifespan of the ro membrane are longer

 

4th

RO membrane, removes the micro impurities, colloid, metal, bacterials and so on, only left the water molecule and dissolved oxygen, output water is purity water.

 

5th

Post active carbon(T33),improve the water pH, avoid the second contamination.















How does it work?

When the source water enters the system it goes through stages one, two, and three, collectively known as the pre-filters. The job of the pre-filters is to remove large contaminants and protect the RO membrane from chemicals like chlorine and chloramines.

After the water has passed through the pre-filters, it is forced through the reverse osmosis (RO) membrane, the same technology used to produce bottled water. This semi-permeable membrane features tiny 0.0001 micron sized holes, equivalent to just 0.000000004 of an inch. This allows it to effectively remove a long list of water contaminants only possible with reverse osmosis.

The fifth and final stage of filtration utilizes a finer GAC filter known as the post carbon filter. This provides a final polishing before the purified water is delivered to the faucet.

The end result is bottled quality water. In addition to the cost savings and health benefits, widespread use of in home filtration systems would reduce the impact of plastic bottles on the environment tremendously. With all of the benefits, it only makes sense to go RO.
