FREQUENTLY ASKED QUESTIONS
Waste Processing Expand AllCollapse All
Desirable feedstocks for the Janicki Omni Processor include wastewater (i.e. digested/undigested sewage sludge, biosolids, residential septage), animal by-products (manure and organic waste), pre-sorted municipal solid waste (MSW), biomass solid wastes, and various industrial waste streams (food and beverage processing waste, distillation by-products, industrial septage). Examples of acceptable MSW include paper and plastic products, domestic household waste, and biomass. The JOP cannot process metal, glass, batteries and several other toxic chemicals.
The Janicki Omni Processor S250 requires roughly 12-15 metric tons of dry waste per day as fuel, or 60 metric tons of wet waste per day into our dryer. The plant can be scaled to a variety of flow rates however.
The JOP S250 is designed to consume the fecal waste or sewage sludge from a population of roughly 300,000 to 500,000 people. However, as long as adequate dry fuel is supplied (approximately 12-15 metric tons/day) from a secondary source (such as garbage, or other solid waste), the JOP can function in a smaller community, providing electricity and drinking water while consuming fecal and solid waste. If there is not enough wet sludge to make drinking water, then ground water can be processed in the JOP and brought to potable water standards. It is also possible to scale the technology down if necessary.
A household model has not yet been built, however, our engineers are working on developing a similar product: a self-sustaining household toilet that combusts waste as the fuel source. As this technology matures, we will provide more details about this product.
Depending on the type and moisture content of the waste streams, the preferred method is to combine any wet and dry material first before feeding or pumping into the dryer. If the waste stream is already dry, an auger mechanism would be used to feed the boiler directly.
Yes, the JOP can process waste with up to 100% moisture content. However, solids concentrations less than 20% may require an auxiliary fuel source to provide the additional energy required to run the plant. Similarly, the S250 can be configured to process or pasteurize grey water with additional equipment.
Yes, the JOP is capable of integrating with a western style system. This would be the ideal location for this type of application due to the fact that the S250 IS NOT designed to act as a standalone treatment system without additional dewatering and solids separation equipment.
When co-located at a wastewater or sewage treatment plant, the S250 would consume the digested or undigested sludge that is separated during treatment. This reduces transportation and further treatment requirements.
Water Treatment Expand AllCollapse All
When the dryer's performance is optimized, the JOP S250 is capable of producing up to approximately 22,000 liters of clean, potable drinking water
The water treatment system integrated into the Janicki Omni Processor works by using a distillation process, multi-stage filtering in the vapor phase, condensing, followed by an additional multi-stage filtration process and aeration in the liquid phase. With the addition of the Water Purification Unit, ozone injection, micro- and ultra-filtration, activated carbon and pH correction are used to take the water to WHO and EPA potable drinking water standards.
Yes, because of our water filtration process, all pharmaceuticals and other contaminants are removed. Furthermore, any heavy metals in the sludge are removed during the thermal oxidation process and fall out in the ash.
Electricity Expand AllCollapse All
The JOP S250 is capable of producing up to 100-200 kW of continuous net power. However, we can easily scale the technology up or down depending on the needs of the application.
Yes. We can build plants that only generate electricity and do not make water. The drier the material, the greater the electricity generation potential.
Yes, the JOP is designed to operate independently of the electric grid. Note: The use of a diesel or natural gas- fueled electrical generator would be required during plant start-up.
Site Details / Operation Expand AllCollapse All
During start-up, the processor requires electricity, an auxiliary fuel source (natural gas or propane), and water. The processor becomes self-sustaining within a couple of hours, at which time the auxiliary fuel source will turn off automatically and the electrical load can be picked up by the plant.
Our processors are designed to operate 24 hours/day, 7 days/week, and shut down only occasionally for periodic servicing or maintenance. Therefore, the consumption of auxiliary fuel and electricity from the grid should be minimal.
At a minimum, a reinforced concrete slab foundation, water drain, and utility connections/conduit are required. Additional requirements specific to the site may be necessary.
The Janicki Omni Processor is designed, engineered, and operated to ensure the exhaust or flue gas meets all applicable federal, state and local air quality requirements. The combination of a highly controlled thermal oxidation process in our fluidized sand bed and the downstream use of sorbent injection, particulate control via a cyclone and a filter baghouse, and other industry-standard control strategies are used to make this possible.
The JOP S250 is designed to minimize the release of odors. The process is under negative vacuum, thereby pulling air into the process, not forcing odors out. However, some odors may be present from other sources, i.e. the sludge or solid waste that is delivered to, or stored on, the site.
The JOP S250 is designed to have a compact footprint of 27 m x 21 m (567 m^2). It is ideal to also have a minimum of 1,200 square meters to allow for trucks and other traffic to access the JOP.
