Miracell® is a fully automatic Rotating Biological Contactor (RBC) wastewater treatment system. A unique feature allows the disks connected to a shaft to rotate at a very low speed by means of a motor which is equipped with a reduction gear. The system is designed such that 40% of the disks remain submerged in the wastewater. The disks which first submerge in the wastewater are then contacted with air. As a result of this repetitive process, organisms accumulate on the disks in the course of time. These organisms receive the necessary oxygen from the air during the rotation of the disks, consume the pollutants existing in the wastewater and convert them to carbon dioxide and water in a totally natural way. The

Miracell® which operates on the RBC principle has many advantages over other package wastewater treatment systems that operate on the activated sludge principle. With conventional activated sludge systems a constant flow of air needs to be pumped through aerators by blowers in order to stimulate bacterial growth. Whereas with the Miracell® system, the bacteria are able to receive the necessary air naturally through the atmosphere.

By design Miracell® has the ability to decrease its capacity in times of ower flow rates via bypassing unused compartments and routing wastewater to the last modular unit to conserve energy costs. Another important feature is the ability to increase capacity by simply adding disks or modular compartments.

The treated water which is discharged from the Miracell® is guaranteed for the most stringent discharge standards and either may be used as irrigation water, or directly discharged into a lake, stream, ocean or other body of water.
