Hi guys,

Thanks for your valuable information. I will describe more about this in clearly

• Industrial park buildings workshops will produce some “oily water” that will be discharged into the sewer network. Additionally, there are detergents and solvents at washing/inspection part of the workshop that again will be discharged to the sewer
• Given that the sewer will have all these oil remains, detergents and solvents, the sewer needs of the Industrial Park needs to by pre-treated on-site before discharging to the External sewer network
• Aramco provided the attached describing the standards of the pre-treated of the sewer effluent that is discharged to Dammam STP to be used as a reference.

What we are looking for is either individual system per workshop or a combined 'site' system for the sewer pre-treatment.

I need a basic pretreatment process diagram sketch. We don't have sufficient data at present

We need to assume min flow
