Desulfurization of oily wastewater
Thread Content
Hello everyone. Recently, I was assigned a project related to the removal of hydrogen sulfide from oily wastewater; the oil content in this wastewater is around 2000 mg/L, the salinity is approximately 100,000, and the hydrogen sulfide concentration is about 200 mg/L. The requirement is that the hydrogen sulfide content at the water outlet be below 1 mg/L. Please let me know if there is any way to solve this.
This wastewater should first undergo oil separation and sulfur removal, followed by coagulation or electrocoagulation; electrocoagulation is energy-efficient under these mineralization conditions, giving it a competitive advantage. Sulfur removal can be achieved using ferrous precipitation, which is relatively inexpensive.
Is this task related to bidding? How will everyone share the results in the future
