Moving Bed Biological Reactor or MBBR Wastewater treatment plants - The Envirosafe from Kingspan Environmental. Certified to NF CE FR EN 12566 - 3

Operation

Moving bed biological reactor wastewater treatment plants or MBBRs WWTPs are the latest and most important development in air blown sewage treatment plants. The Envirosafe from Kingspan Environmental is designed around a three chamber wastewater treatment system, the moving media within the second stage treatment tank is designed to continuously self clean, preventing the “channeling” or clogging of the bacteria supporting material often found in submerged aerating filter wastewater treatment systems. One chamber is called PST (primary settlement tank), the second one called biozone, and the third stage is called FST (Final Settlement tank) The PST acts as a pre-treatment tank, the "biozone" is an aerated holding tank with a predetermined quantity of freely circulating media and the FST performs a final clarification. Within the primary chamber, large solids are removed by settlement and flotation. An accumulation forms at the base of the tank and is removed annually or biannually through de-sludging. The clarified water then passes to the aeration chamber where it is treated to remove the dissolved organic content. Mobile media elements supporting large bacterial populations within the reaction chamber are agitated and mixed by compressed air bubble cascades promoting complete mixing ensuring that full treatment is achieved. Unlike conventional wastewater treatment plants in France, The Envirosafe from Kingspan Environmentals MBBR systems are self cleaning and unable to become blocked through channeling or clogging. Treatment media interactions produce a sloughing effect that removes excess bacteria, ensuring continuous re-growth and optimising overall reactor efficiency. The treated effluent and sloughed off bacteria flows into the final settlement tank where any remaining small solids settle out before the clarified effluent is discharged from the MBBR wastewater treatment plant.
