The modern toilet design, while functional for areas with access to centralized sewage systems, is not suitable for many locations and is highly wasteful. The need for a better sanitation solution in the developing world and a less wasteful solution for the developed world is clear.
Sedron has developed the Firelight Toilet, a complete blackwater recycling system that achieves:
- 100% pathogen destruction
- Nutrient removal
- Recyclable flush water
- Phosphorus-rich, dry byproduct
- Modular design that allows system to be applicable in a variety of use cases
The Firelight Toilet is based upon a proven, energy-efficient process known as mechanical vapor recompression. The waste is separated into solid and liquid fractions through thermal evaporation. The resulting vapor is then run through a pump to increase temperature and pressure. This pressurized vapor then becomes the heat source for the evaporation process, increasing efficiency by recapturing the energy of the most energy-intensive process in the cycle: phase change. In transferring its heat, the pressurized vapor condenses and forms a water output. The separated solids are metered into a controlled fire for further volume reduction and energy recovery within the system.
COMPATIBLE WITH SEWER & SEPTIC SYSTEMS
The Firelight Toilet eliminates the blackwater loading on traditional sewer and septic systems, and has the potential to replace the need for costly septic to sewer conversions in areas where uncontrolled nutrient loading is a concern.
100% of phosphorus is removed and concentrated through distillation into a manageable solid output. This significantly reduces nutrient loading on local ecosystems.
All liquid effluent meets regulatory reclaimed flush water standards and can be disposed of without uncontrolled nitrogen loading on local ecosystems.
The Firelight Toilet kills 100% of pathogens present in the blackwater waste stream.
The Firelight Toilet recycles flush water, benefitting both the environment and utility costs.
The system’s thermal and mechanical process is not susceptible to biological or chemical upset conditions requiring long process recovery times. No process chemicals required.
REAL ESTATE EFFICIENT
Compact footprint compared to competitive technologies such as septic and sewer, and less disruptive to install or maintain since the unit is entirely above ground.
The Firelight Toilet provides the potential to replace traditional wastewater treatment processes including septage and sewer treatment plants, offering capital and operating cost savings.
