This just illustrates one point: if the sludge in your oxidation tank is not expanded and the dissolved oxygen level meets the requirements for biological processes, it means that sludge removal from your secondary sedimentation tank is not carried out in a timely manner, as some of the sludge cannot settle under anaerobic conditions. Of course, if there is a problem with the biochemical sludge, it’s necessary to address the root cause; only by identifying the problem can it be solved.
My process is BAF. . . . . .
Do you regularly backwash the packing? It’s possible that your BAF is already overloaded:$
Of course, it is first necessary to determine whether it is caused by sludge bulking or by an increased water flow resulting in insufficient retention time.
My BAF is indeed overloaded; a simple sedimentation tank won’t work. The depth of my testing tank is 4 meters. I would like to ask everyone: what are the effects of slightly aerating the testing tank? I look forward to hearing everyone’s opinions
It seems I really have come to the right place, hehe. Our company specializes in filters, with precision ranges from 10um to 3000um; they can effectively remove sludge (I hope the original poster won’t mistake this for AD and report me). Here’s a website for you: www.cnluolun.com.
Reply to 8# kouxj: Are there atmospheric pressure filters? ? Flow in by itself
Reply to 9# Yuru Yucheng: To be honest, atmospheric pressure filters don’t work very well and don’t provide thorough filtration. The backwash filters used in our company fall into the category you mentioned. You should come to the company to learn more about them in detail
