MBR, MBBR and FBBR – Comparison of wastewater treatment technologies (PART 2)

Featured Video Play Icon

The comparison of the three systems show different advantages and disadvantages for industrial wastewater applications: 1.       Effluent water quality: MBRs show in general a slightly better BOD removal than MBBRs or FBBRs. Very fine membranes can even hold back germs so that the water effluent quality is in general better. 2.       Resistance to influent peaks […]

MBR, MBBR and FBBR – Comparison of wastewater treatment technologies (PART 1)

Featured Video Play Icon

MBR, MBBR and FBR are widely used technologies in wastewater treatment especially for industrial applications with a high BOD loading such as food and beverages, dairy, chemical, leachate and others. As industrial applications usually have volatile water inflows, equalization tanks are used for water storage and eventually PH neutralization as well as flocculation. Afterwards screens […]

Fixed bed bio reactor (FBBR) – Poultry processing plant

Situation: The Hurlock, MD poultry plant processes about 300,000 chickens per day which equals a total flow of 1.3MGD (4 gallons per bird). The existing process strain included a DAF unit and wet well. The effluent wastewater of the DAF unit was 530mg/l BOD, 95mg/l TKN and 106mg/l TSS. However the discharge permit is 425mg/l […]
