Minimum Electricity Consumption,
Space-Saving

Developed through Miranda's own R&D efforts, Miracell® is a fully automatic wastewater treatment system especially designed for domestic wastewater treatment applications in capacities ranging from 50 people to 30.000 people. Representing the ultimate in wastewater treatment systems, Miranda consumes as little as one fifth of the electricity and requires as little as one third of the space of its competitors based on the activated sludge technology.

Biodisk Technology

The operating principle of the Miracell® wastewater treatment system is based on the Rotating Biological Contactor (RBC) technology in which disks connected to a shaft are rotated 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 in the wastewater. 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 necessary oxygen from the air during rotation of the disks, consume the pollutants existing in the wastewater, and convert them into carbon dioxide and water in a totally natural way.

Miracell® which operates on the RBC principle has many advantages to other package wastewater systems based on the activated sludge principle. In package wastewater systems which are based on the conventional activated sludge principle, a constant flow of air needs to be a pumped through aerators by blowers in order to stimulate bacterial growth whereas in the Miracell® System, the bacteria are able to receive the necessary air naturally through the atmosphere. Thanks to this basic difference in the operating principle and due to the fact that the system only requires a small motor to drive it, Miracell® operates silently while consuming much less energy than its competitors.

50-20.000 person service capacity

Miracell® systems are fabricated from fiber reinforced polyester which eliminates any concerns for deterioration from the corrosive effects of alkali maters in the system and the wear-down effect of harsh environmental conditions including Ultraviolet rays. Periodic painting and maintenance which are common concerns for systems manufactured from steel are not applicable for the Miracell® The discs in the system are also made of corrosion-proof polyethylene which is a preferred material in the chemical industry for storage of harsh chemicals. Together, these advantages combine to make Miracell® a virtually indestructible treatment plant with little or no maintenance problems.

One of the most important features of the Miracell® System which is not available in any other package wastewater treatment alternative is the ability to increase the capacity of the current system by simply adding disks or 10, 100 or 250 people equivalent modular compartments. Additional capacity increase can also be achieved by usage of the optional frequency converter that can increase the speed in which the disks rotate are thereby increasing aeration.

Thanks to its modular design, Miracell® is the only package wastewater system which has the ability to lower its capacity in times of lower flow rates via bypassing unused compartments and routing the wastewater to the last modular unit in order to converse valuable energy. Because of its modularity, Miracell® can also be easily transported in the event the operation is relocated.

Water in its Purest Form

Miracell® eliminates the problem of foam formation arising from high turbulence and/or bubbling due to the aeration process, which is especially encountered in wastewater that contain dissolving substances. Miracell® system is also much more resistant to unexpected circumstances such as short or long-term power interruptions, shock organic loading and sudden increases or decreases in the incoming water flow-rate.
