strength of COD for your waste stream - some details needed

Hello Gary  - How are you?

What strength of COD are you talking about for your waste stream?

One plant I am working with right now has a COD strength of their influent from 6000mg/l to nearly 30,000mg/l depending on the time of year and their upstream process. The system is designed with an HRAD (High Rate Anaerobic Digester) ahead of the membrane bioreactor. This process dramatically reduces the COD and at the same time produces methane which is recovered and used by a CHP system for offsetting power consumption by selling it back to the power provider.

What is your bioreactor designed for COD wise?
