I would like to ask how to reduce suspended solids in the wastewater system
Thread Content
Our factory operates in the coal chemical industry, focusing on the production of methanol. The domestic wastewater and process water treated here are mostly high-COD wastewater; the biochemical method used is SBR, while physical methods include collection tanks and oil separation tanks. Biological film methods involve BAF – biological aerated filters – as well as secondary sedimentation tanks and ozone treatment tanks
Is the question not expressed clearly enough? Which section of the system has high levels of suspended solids in the wastewater? Is water coming out? To address issues such as turbid water and high levels of suspended solids, it is generally necessary to add an advanced treatment process after the biochemical treatment, using physical and chemical methods for removal
Just add a bypass filtration system to the system, right? ? ?
Just use a sand filter and clean it regularly.
Add a primary sedimentation tank before the biochemical wastewater enters; if that doesn’t work, add a sand filter. There is a BAF after the effluent exits; theoretically, the SS level in the effluent from an SBR system after passing through a BAF should be below 30. I’m not sure how you operate it
