How does it work?

Crude wastewater enters the main outer chamber (1) where the initial settlement takes place, with the heaviest solids sinking and the floating matter rising. The liquor from the main section is transferred to the central chamber (2) where it’s continuously aerated by the fine bubble diffuser (4) which encourages bacteria to provide the second stage of treatment.

The mid-section of this treated effluent is then removed from the chamber through a calming pipe (5) which allows a further brief settlement before discharge. (6)

The air compressor (7) runs continuously. It is contained within the neck of the tank and it’s accessible for maintenance if required.
Easy access is available to both chambers for dislodging which is an annual operation.

How does it work?

The Balmoral Hydroclear system incorporates a full size three chamber design, i.e., primary settlement, aeration chamber and final settlement.

Within the primary settlement chamber, large solids are removed by settlement flotation. An accumulation forms at the base of the tank and is removed annually or biennially 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.

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 regrowth, optimising overall reactor efficiency.

The treated effluent and sloughed off bacteria flows into the final settlement chamber where any remaining small solids are removed prior to the clarified affluent being discharged from plant.
