3. Working principle

As representatives of the RNa sodium resin , the exchange process is as follows:

2RNa + Ca2 + = R2Ca + 2Na +
2RNa + Mg2 + = R2Mg + 2Na +

The water through the sodium ion exchanger , the water, Ca +, Mg + is replaced by Na +.
General control valve operation process is: run , backwash , brine , slow wash , salt water tank , flushing .

Underground Water With Iron And Manganese After Treating By Aeration, Iron And Manganese Ions In The Water Starts To Be Oxidated, Iron(Fe²⁺), Manganese(Mn²⁺) Exists In The Underground Water (Well Water), Mno2 In The Manganese Sand Can Catalyze The Oxidation Of Fe2+, Mn2+, To Generate Insoluble Trivalency Iron And Tetravalent Manganese, Then Use The Back Washing Function Of The Manganese Sand Filter To Get Rid Of Iron And Manganese And Make The Source Water Purified.

4. Characteristic

Power Saving: The Water Can Be Supplied To The Pipe Network Directly, No Need To Set Up Second Stage Water Supply System, The Equipment Has Backwash Function, And No Need To Set Up Backwashing Pump.

Water Saving: This Equipment Adopts "Plum Blossom Water Distributor", Which Can Shorten The Distance Between Filter Layer And Water Distribution Pipe, And Can Save a Lot Of Backwash Water.

Save Investment And Floor Space: The Equipment Is No Need To Set Up Clear Water Tank.

Save The Filter Material: This Equipment Water Distribution Is Balance, The Filter Material Does Not Have The Dead Angle, Does Not Harden, Prolongs The Filter Material Service Life. A Strong Oxidation Chamber Sets Up Inside The Equipment, Which Can Increase The Saturation Of Air And Water, Speed Up The Oxidation, And Have Stronger Applicability To The Content Of Iron And Manganese In Raw Water.
