How is saline wastewater from various refineries treated?
Thread Content
I would like to ask everyone: how is the saline wastewater from various refineries treated after passing through the saline wastewater treatment plants? Has everything been released? Are they all zero-emission now? Vaporized? Entered the concentration tower? A guy asked me about their factory’s wastewater, which amounts to 30 tons per hour and has a salt content of 1%; all other parameters meet the first-class discharge standards. What do people think are the best ways to handle this situation? By the way, I’d like to know how other refineries handle saline wastewater treatment.
I haven’t worked on saline wastewater before; I’m not an expert in this area. However, many relevant materials have been posted on the forum these days, including papers and treatment solutions. You can go and take a look at those.
The OP’s question is quite interesting. A salt content of 1% is by no means considered high-salinity wastewater, so there is no need to raise such a question. As a person at the engineer level, it’s not quite appropriate. Haha. Zero emissions, evaporation, concentration? A small error can lead to huge mistakes. For reference only; speak carefully!
