Is there a centrifuge that can be used for treating sludge from concentration tanks in the AAO biochemical treatment process without the need to add PAM (flocculant)?

Reply 1# liu2c: Flocculants are generally added; otherwise, the small particles cannot aggregate into larger ones.
Adding it is the standard procedure; not adding it means using the reality
If sludge concentration is effective during the coagulation tank, flocculation tank, and thickening tank stages, it may also be omitted. Generally, the suspended solids and COD in the effluent also do not exceed the limits. :lol
Adding it is the standard procedure; not adding it is what is used in reality – we can’t reject everything outright~! The composition of wastewater treated in different places varies! Just like in many gasification plants, flocculants must be added to the wastewater treatment!
