Reverse Osmosis Water Treatment System
1. Quartz Sand Filter
Main usage: Clear the sediment, manganese, rust, colloid material, mechanical impurities, suspended solid and other particles whose volume is more than 20 UM.
The effluent turbidity is less than 0.5NTU, CODMN less than 1.5mg / L, iron content of less than 0.05mg / L, SDI less than or equal to 5.
2. Active Carbon Filter
Usage: the active carbon filter is used for removing the pigment, smell, chemical and biological organisms, reducing the pesticide pollution and other harmful pollutants in the water.
The active carbon in the filter have strong adsorption capacity, and it can clear the organic material which is not cleared by quartz sand filter, and also will adsorb the residual chlorine in the water, and then the chlorine content in the water will be less than 0.1ML/m³, SDI less than or equal to 4, which will protect the membrane in reverse osmosis device. As we know the reverse osmosis membranes are very sensitive to chlorine.
And also the the active carbon filter can adsorb part of the metal ions in the water.
3. Sodium Filter
Cationic resin in the precise filter is mainly be used for softening the water, reduce the hardness of water.
As we know the hardness is mainly because of the calcium( Ca 2+), magnesium(Mg 2+) ion composition. After passing the filter, the Ca2 +, Mg2 + will be exchanged by sodium cationic.
