Can You Really Drink Water Made From Sewar Sludge?

Yes! It's No Different Than Bottled Water

Because we heat the sludge until it boils, water exits the dryer as steam. At this temperature, pathogens cannot survive. While the water is in the vapor phase, it is filtered to remove particles. We then take this bio-safe steam and condense it to water before putting it through water treatment. The machine's water treatment adjusts the pH, and uses multiple filters to ensure safe, clear, great tasting water. The water is indistinguishable from bottled water.

Model S100 can produce up to 10,800 liters of clean drinking water per day, satisfying all United States FDA and WHO clean water requirements. Emissions also meet or exceed all applicable United States EPA requirements.

Test Site: Dakar, Senegal

Model S100 is scheduled to ship to Dakar, Senegal in mid-February 2015. This location is perfect for continuing development and measuring real-world performance, making sure that the Omni Processor works reliably in all locations, and Dakar will provide with an opportunity to establish support channels, supply chain, and logistics in Africa.

  • How Much Water can be Produced?  10,800 liters per day

  • What is the Machine Footprint?   8m X 23m
  • What Type of Fuel does it Use?   Sewer sludge
  • What is the Maximum Moisture Content of the Fuel?  84%
  • What Standards does it Meet? The drinking water meets both US FDA and World Health Organization Standards

S200-plant-layout

The first commercial Omni Processor (OP), Model S200, will be a stationary combined heat and power plant that converts fecal sludge and other combustible waste streams into electricity, potable water, and ash. The heat from combustion within a fluidized sand bed is utilized to generate high pressure steam that is expanded in a reciprocating piston steam engine connected to a generator, producing electricity. The exhaust from this engine (process heat) is used to dry the incoming fecal sludge. The water that is evaporated out of the sludge is then treated to meet clean drinking water standards. The combustion gases are treated as necessary to meet local emission standards.

Remote Operation:  The OP will be connected to the internet and remotely monitored and operated by a central command center. This will provide technical expertise to each unit without requiring technical expertise physically at each unit. Additionally, this will provide access to software upgrades for the customer continually increasing the performance of their unit.
