I am an engineer working for www.phakee.com over 30 years which Professional in water & wastewater treatment, Air pollution &Gas treatment. As insufficient information on your post that I only suggestion by roughly as following.(Pre-treatment by DAF  and Post treatment by activated sludge)

Basic treatment diagram as below

InfluentàRaw wastewater tankàNeutralization tankàFlocculationàDissolved air floatation tankàActivated sludge by MBR.-à Effluent

1. First of all, the batch wastewater from CIP process and CEP process during cleaning production line process. Both wastewater have to balance by mixing with the continuous wastewater, because it has to continuously control Q&Q of wastewater before entering to treatment system.

2. Neutralization by adding coagulant aid herein is Ca(OH)2  to ​raise your  pH.7

3. Flocculation by adding An-polymer 1-2 ppm.

4. To Removal suspended solid, oil and grease by DAF. Recommend advance technology such as Micro bubble pump use to generating fine bubble which replace saturate pressure tank

5. To Removal organic matter in term of BOD, COD by activated sludge with MBR. Technology. If the contaminate has low organic matter you can oxidizing by chemical to decompose it, High contaminate will not economical by chemical.

Would you like to get more information? Please give me more information as following.

1. Wastewater qualities and quantities of Influent and effluent

2. Existing treatment process diagram or recent treatment process diagram.
