Can the whole membrane method treat coking wastewater?
Thread Content
, can the whole membrane method be used to treat coking wastewater? Is the technology mature? Are there any treatment examples?
The technology is not mature, it seems to be useful in Shandong, but the maintenance is not good enough.
Whether it is mature or not depends on how much you have to spend on pre-processing. The information you gave me, the poster, is too little. If you are interested, we can discuss it. suminglue@filterox.com .

thank you all: The coking wastewater that needs to be treated now is the coking wastewater that has been biochemically treated. The specific water quality index is COD: 150 NH3-N: 12 PH: 7.5 phenols: 0.4 CN-:0.5 In addition, there are still some colors that need to be treated as supplementary water for circulating cooling water.
There should be no problem with this indicator. The ammonia removal rate is still relatively high and the COD is not large, but the membrane fouling problem will be relatively large. It is best to clarify the specific indicators of circulating cooling water. I feel that the standards required by each owner are different, and the cost and operating expenses are also very different.
