Treatment of wastewater generated again in the resin tower
Thread Content
Next to our plant’s resin tower, there is a tank dedicated to discharging the regenerated wastewater. However, uneven mixing often affects the regeneration process of the resin tower. What can be done to solve this issue? Are there any other good solutions?
Acidic water, alkaline water, and recycled brine are stored separately
There is only one pool; the main thing is to ensure even mixing
Compressed air or nitrogen can be added to the pool, along with agitation; generally, if control is not proper, the wastewater becomes acidic, which can corrode equipment.
To adjust to neutrality, balance acids and bases and then add pH remote control
Can your wastewater tank hold all the reclaimed wastewater? If it can all be stored, a small amount of alkali can be added, and then compressed air can be used to stir and neutralize it
Just pour it directly into the saline mixing tank – why mix it? The concentration of the saline can be adjusted directly there
Add a mixer; mix well before each regeneration before proceeding
D-165 is directly converted to monosalt； Add a DN25 pipeline on the line from D-166 to P-166 (to add caustic soda), and add a return pipeline from P-166 to D-166; this way, the pump and storage tank can be used to adjust the pH value through circulation. Once the pH value is adjusted properly, it can then be sent to the first-stage salt production unit
There is no need for external discharge at all; the water generated can be recycled 100%
