The SV30 supernatant is turbid
Thread Content
Phosphating wastewater + biochemical sewage: the treatment process involves hydrolysis and acidification, followed by contact oxidation and MBR. The designed capacity is 320 cubic meters per day, while the actual amount of wastewater entering the system is 180 cubic meters per day. On weekends, only about 50 cubic meters of biochemical sewage need to be treated. The COD level of the incoming wastewater is around 300, TP is 5, and ammonia nitrogen is 18. It has been observed that the supernatant fluid in the SV30 unit is turbid. Could you help analyze the reasons for this and suggest solutions? Thank you
Based on your description, it might be due to low load or sludge aging
