Low Energy Demand
RBC System saves up to 90% in energy costs. Among all known wastewater treatment technologies, RBC is the one that consumes the least amount of energy.
A typical blower for an activated treatment plant with a capacity of 250-350 pe requires 4-5.5 kW. For a similar capacity plant, PlanetDISK® uses a 0.37 kW electric motor and a reduction gear to rotate the rotor at 3-5 rpm. That is all the energy required in the reactor part! Monthly energy costs per person per month at a typical PlanetDISK® plant are less than $0.1.

Renewable Energy Resources
Due to the system’s low energy demand, it is easily operable with either solar or wind power.

No Smell No Noise
No annoying smell or noise. The rotor rotates at 3-5 rpm and requires merely 0.37 kW. It is quiet! Each time the rotor surface is exposed to the atmosphere, plenty of oxygen diffuses to all the bacteria in the biofilm. There is no blower to blow the smell out of the system. One can place PlanetDISK® unit nearby a swimming pool.

Dependable Under Variable Loads
Consistent process results even the organic load may vary up or down by 250%. Since the microorganisms in a fixed-film system are attached to a media, they cannot wash out with increased flows or loads. In villages or gray water projects, even though the bacteria levels are low and the wastewater is diluted, the system still performs well and delivers the required standards.

European Standards
Nitrification, denitrification, and phosphorus removal are all successfully achieved by RBC systems. When the effluent BOD level is below 15 ppm, nitrification is achieved. When the water is fed back to one of the sedimentation tanks acting as an anaerobic tank, partial denitrification occurs. Phosphor removal is achieved by flocculation or filtration. Effluent values of 10-15 ppm BOD can easily be achieved by PlanetDISK RBC systems.

Reuse of Waste Water
With tertiary treatment (sand+activated carbon filter) and disinfection (UV or chlorine), treated wastewater can be used for irrigation, car wash, toilet flushing, cooling tower water, and also at construction sites.

Easy Maintenance
Simple and economical to run. Does not require constant maintenance as required in activated sludge system

Long-Lasting
All the materials used in manufacturing PlanetDISK® units are corrosion-proof. HDPP disks, HDPE or GRP body tank, the rotor which is in contact with water is SS and/or galvanized metal. The solid shaft is chrome plated and/or epoxy paint protected. It is designed and built to serve many years. Heavy-duty bearings are pillow block types with self-aligning spherical roller bearings. Disks are made of 1 piece all new virgin material.
