Design of Oil and Grease Trap and MBBR Tank

I have to install 500 KLD of STP plant for one of our clients in India.

The inlet parameters of this plant are.

• BOD=350 mg/l
• COD=700 mg/l
• TSS= 850 mg/l

Rest of the parameters can be assumed.

The question is - what capacity of oil and grease trap and MBBR (aeration) tank we would have to construct for this plant?

Best regards
