1. Heat the chlorine water using a dechlorination tower to recover the chlorine gas, while discharging the water into the waste separation system. 2. It can be used to produce sodium hypochlorite, which is applicable in PVC systems or for takeout. 3. When used for ordinary wastewater treatment, chlorine water may have a strong odor. The above are merely personal opinions.
After being dechlorinated in the dechlorination tower, chlorine water is sent for reuse in the primary brine cycle.
Chlorine water can be used in the following areas: 1. It can be recycled into the brackish water system, where its pH is adjusted before dechlorination and recycling. 2. Sent to the epichlorohydrin unit for recovery and reuse. 3. Go to the Kaimei membrane section and add No. 2 baffled tank to decompose organic matter and remove ammonia, but the pH value needs to be adjusted. 4. Go to the sewage treatment plant.
It can also be used in the circulating water process for algae removal, but the dosage needs to be controlled properly.
1. Used for the production of sodium hypochlorite. 2. Transport the chlorine water from the system to the dechlorination tower, where it is dechlorinated together with the electrolyzed brackish water. 3. The wastewater is sent to the sewage treatment process; during this treatment, chlorine gas is released, contaminating the air and posing a risk to the health of employees. It is recommended to keep the pH level of the wastewater at an alkaline value. Of course, it is within the controlled range of the pH value at the time of emission.
1. After dechlorination in the dechlorination tower, it can be returned to the brine station for salt production. 2. Saving one amount of water can also reduce the total ammonia level in the saline solution.
