For wastewater stripping units, how can the levels of hydrogen sulfide and ammonia nitrogen in the wastewater at the bottom of the tower be reduced to the greatest extent possible? Is it possible to reduce the hydrogen sulfide level to less than 1 mg/l and the ammonia nitrogen level to less than 30 mg/l? What process adjustments or technical upgrades can be implemented?
The quality of the product at the bottom of the tower depends on the properties of the raw water used; high levels of ammonia nitrogen and sulfides are not acceptable. If the wastewater contains too much alkali, the sulfide levels at the bottom of the tower will be unsatisfactory. In such cases, it might be advisable to increase the height of the stripping tower, which would yield better results.
When it was constructed, the design institute developed the design based on the overall conditions of your factory; if changes are needed beyond what was designed, a new set has to be built
If only H2S gas needs to be removed, our company’s chelated iron process can be used to achieve ultra-low emissions with no waste generation, and the system operates stably.
