What types of containers do your odor control devices handle to remove the odorous gases from? How often should the water and solvent in this device be replaced?
Now, the water needs to be changed once a week； The absorbent is replaced approximately once a year. Currently, the waste gas from the underground tank is directed to the sulfur unit, while the gas from the fractionation tank is sent to the raw water tank.
