It is sent directly to the dechlorination process; after dechlorination, it is either converted into salt or discharged directly, and it is generally not absorbed.
It is sent to the dechlorination process; after dechlorination, the salts are removed. Part of it can be used in the circulating water system
First, use chlorine for washing and cooling, and then proceed with dechlorination
It can also be used in the waste gas treatment process to produce sodium hypochlorite or bleaching solution.
Sent to the dechlorination process; after dechlorination, it is sent for desalination
It is sent back to the electrolytic anode solution discharge tank, then to the dechlorination process; after dechlorination, it goes on to the desalination step
Based on the conditions in our plant, a level control valve is installed at the outlet of the chlorinated water from the chlorine scrubber tower. When the liquid level exceeds the set value, the chlorinated water is sent to the electrolytic anode liquid discharge tank; after being heated, it is fed into the dechlorination system for dechlorination. Finally, it returns to the primary brine along with the fresh brine to undergo further processing, thus enabling reuse and saving resources while also being environmentally friendly.
The more common approach is to recover it through pipes into a storage tank, and then pump it into the dechlorination pipeline where it enters the dechlorination tower together with the brine coming out of the tank, so that chlorine can be removed; the chlorine and the brine are recovered separately. The chlorine goes into the main chlorine pipeline, while the water returns to the primary brine for reuse
