Issues regarding the Caimei membrane process and biochemistry for centrifugated mother liquor

Thread Content

Currently, there are two main methods for treating centrifugated mother liquor (only direct reuse in polymerization is discussed): one is the so-called dual-membrane reuse process, and the other is the biochemical treatment process. However, I have some suggestions regarding these two processes, and I would like to invite experts to participate in the discussion: (1) The dual-membrane method involves direct treatment, resulting in no obvious secondary pollution in the water body. But due to the lack of degradation of organic substances, all the burden of removing these organic substances falls on the membranes, which limits their service life and reduces the stability of the process. (2) Biochemical methods can be used to effectively degrade organic matter, and membrane techniques can be employed to mitigate membrane fouling. But what I would like to point out is that, according to the biochemical process, bacteria are used as the main mechanism for organic degradation within this process. Based on my understanding of biochemistry, bacteria simply use organic substances as a source of nutrition; where there is growth, there is also death, and therefore a large number of dead bacteria exist within biochemical systems. After bacteria die, their cell structures break down, and some of the organic substances are released again. Moreover, during their growth process, bacteria secrete large amounts of organic proteases and extracellular polymers. Although these substances are not present in high concentrations, they can significantly alter the composition of organic matter in water bodies. If such wastewater is reintroduced into the polymerization process, will it have a serious impact on the polymerization? Moreover, it is difficult to see obvious results from this cumulative effect in a short period of time; over the long term, it will inevitably change the proportions of the polymers, affecting the quality of the product. Has anyone considered this issue and what are their thoughts?
