An aerated biological system, the HydroClear benefits from a moving bed biological reactor, or MBBR, at its core. A new process in the package wastewater market, MBBR technology embraces the benefits of fixed film media processes without suffering their downfalls.
Overgrowth of bacteria leading to ‘channelling’ is an issue with common process designs such as submerged aerated filters (SAF), rotating biological contactors (RBC) or trickling filter (TF) designs.
Unlike conventional media beds, MBBR systems are self cleaning and unable to become blocked through channelling. Media interactions produce a sloughing effect that removes excess bacteria thus ensuring continuous re-growth, optimising overall reactor efficiency.
The Balmoral HydroClear system incorporates a three chamber design, ie, primary settlement, aeration chamber and final settlement.
Within the primary settlement chamber, large solids are removed by settlement and flotation. An accumulation forms at the base of the tank and is removed by desludging.
The clarified water then passes to the biological reactor where it is treated to remove the dissolved constituents. Mobile media elements support large bacterial populations within the reaction chamber while induced air promotes complete mixing ensuring that full treatment is achieved.
The treated effluent and sloughed off bacteria flows into the final settlement chamber where any remaining small solids are removed prior to the clarified effluent being discharged from the plant.
