As the HC Technology the BSK Surface aeration process includes two necessary operations, the oxygen input and the permanent homogenisation of the reactor volume. A swimming support keeps the aeration turbine in a exactly adjusted semi submersible position. The rotating turbine plates effect strong hydrodynamic turbulences on and under the wastewater surface, pressing and swirling the air from outside into the reactor volume, The turbulences under the water surface course a strong circulation of the entire reactor content and with that, an optimal distribution and absorption of the oxygen.
The patented BSK aeration technology is a excellent stand-alone solution, needing not any additional pressed air supply, pipes or input devices. Its development has been directed to a high oxygen input performance and efficiency as well as the reduction of maintenance and energy costs. By a additional electronic oxygen measure and drive controlling system the efficiency and economy of the system can be further optimized.
And not at least - the BSK surface aeration technology is practicable in several other biological treatment processes as nitrification, de-nitrification and sludge stabilisation.
