We’re designing a small industrial wastewater line (food processing, COD swings) and debating the best way to size and operate an Anaerobic Bioreactor. What HRT/OLR ranges have actually worked for you, and how do you plan for shock loads, foaming, and start-up seeding? I’m comparing vendors, including Ritai Bioreactor, and want practical notes on mixing, biogas treatment, odor control, and day-to-day maintenance in real plants.
