An aerated biological system, the HydroClear benefits from a moving bed biological reactor, or MBBR, at its core. A new process in the package waste water 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. In France this is known as a microstation d' epuration.

Within the primary settlement chamber, large solids are removed by settlement and floatation. 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.

        A summary of what makes the Balmoral HydroClear so special


•Class-leading performance The HydroClear produces an astonishing market leading pollutant removal level of 97%. Carrying full CE accreditation to BS EN12566-3, final values are achieved for BOD, SS and NH4-N of 10:13:6mg/l respectively.

• Lower operating costs With its unprecedented 24-month service period and enhanced capacities the HydroClear can dramatically reduce long term operating costs. This is achieved through the inherent reliability of the simple but effective design rather than using complex systems that require frequent maintenance and desludging to achieve optimum performance.

• Easy installation Further benefits are realised from the outset with optimised design characteristics meaning the 6-popmodel can be installed using a 2.5-tonne mini-digger rather than the 7 or 12-tonne machines required for traditional plants. These design values are reflected across the entire HydroClear range resulting in simple, cost effective installation with minimal damage to the surrounding area.

• Power failure default Even if the power fails the HydroClear will continue performing as a septic tank to ensure continued environmental protection.

• Silence is golden High performance diaphragm blowers are used across the full range of HydroClears providing virtually silent operation. • Odour minimisation Hermetically sealed and market leading performance means the HydroClear effectively combats odour production.

• 6-50-pop options The HydroClear is available in 6, 12, 20, 30, 40 and 50 population models, in single or multitank designs, depending on size, offering a highly flexible solution to space-limited sites.
