Preliminary Research and Documentation

The following research and documentation is meant to get this project started. Please consider this a work in progress. Significant work is needed to move this project forward.

 

Components

  • Flushing toilet system - to collect waste
  • Separator/Filter - tp separate solid particles from dirty water
  • Incinerator chamber - to burn solid waste 
  • Waste water chamber- collect the water and send it for further purification

Method

The incinerator toilet is a regular flushing toilet that can collect waste. When the toilet is flushed, the contaminated water goes through the drain. A filter in the drain separates solid waste from liquid waste. The filter is installed at an angle of 60°. This allows for the solid waste to slide into the incineration chamber.

A high powered propane burner burns the solid waste. 

The resulting water is collected in the waste water chamber and is pumped out for further purification using electrocoagulation or other methods of water purification. 

 

Additional Research

Researchers at Cranfield University, UK, have developed the Nano Membrane Toilet which treats human waste onsite without the need for flush water. The Cranfield toilet is designed for single-household use (equivalent to 10 people) and will accept urine and faeces as a mixture. The Cranfield toilet flush uses a unique rotating mechanism to transport the mixture into the Cranfield toilet without using any water whilst simultaneously blocking odor and the user’s view of the waste. 

Solids separation (faeces) is accomplished by separating the solid matter from the mixture using an Archimedes screw that  transports pellets of solid waste to heat exchange chamber. The solid matter is then incinerated in the heat exchange chamber and converted to ash that can be disposed off periodically in an eco-friendly manner. The separated liquid is passed through a nanomembrane for treatment and purification. This treated and purified water can be reused for other purposes like washing, gardening or flushing.
