high adhesive properties anionic polyacrylamide in brazil
As the sodium ion has solubility in the water, it will not form a hard scale and will be easily removed. The water in sodium ion exchanger shall be clarified and filtered and there will be no suspended matter. After softening through the exchanger, the water has a residual hardness no more than 0.03mg/l.
The sodium ion exchanger that uses sodium ion as the exchange ion is sodium ion-exchanger. The alkalinity and hardness in raw water is quite high. When raw water enters into RO (Reverse Osmosis) module, with forward move of water, desalted water exudes continually and the concentrated solution gets denser and denser.
