The Problem

The existing rotating biological contactors (RBCs) were approaching the end of their service life and presented constant operational issues. Additionally, the RBCs were not completely removing the formaldehyde concentrations in the wastewater.

The Solution

bioprocessH2O supplied a two-stage bioFAS™ MBBR biological treatment process to reduce BOD and formaldehyde at varying flow and organic loading rates.

The Results

The bioFAS™ MBBR System effectively removes BOD by >90% and easily meets the NPDES Discharge Permit Requirements. The system is able to operate with minimal operator attention and oversight. Additional details can be provided by bioprocessH2O
