The problem of ion or organic compound enrichment in three-effect evaporation
Thread Content
When three-effect evaporation is used to treat wastewater containing ammonium chloride, after continuous evaporation and concentration, the organic substances or other impurities present in the wastewater cannot be vaporized nor can they crystallize out; as a result, they continue to accumulate within the system. Everyone knows what the consequences of such accumulation are. Do any of you experts have any effective methods for continuously removing these impurities?
In multi-effect evaporation for wastewater treatment, a small amount of concentrated phase always needs to be removed from the system regularly; otherwise, it will affect the treatment capacity
What should be done with the concentrated phase that is discharged? After all, it is very difficult to evaporate this enriched material... Are there any good methods available in the design and implementation of multi-effect evaporation to address this issue?
I think it’s a common issue... It seems like no one in the forums has discussed it... Help! ! ! Could it be that this involves some fundamental aspect, which is why everyone remains silent?……
Push it every day; I hope some expert will be able to see it……
In fact, whether it’s four-effect evaporation, three-effect evaporation, multi-effect evaporation, MVR, or anything else, this problem generally arises during the process of evaporation and concentration, right? Why has so few people mentioned this issue, whether in literature or forums? Strange, strange……
Push it every day; I hope someone experienced can see it……
