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
Figure 1 - Sample set up of the incinerator toilet.
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=high powered propane incineratorburner 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.
An
Related electrocoagulation unit consists of an anode and a cathode that are connected to a DC power supply. When contaminated water flows into an electrocoagulation unit, the following reactions occur:
From the anode, metallic ions are released into the contaminated water.
On the cathode, water is hydrolyzed, forming hydrogen gas (H2) and hydroxyl (OH) particles.
Electrons move from the cathode to the anode. This destabilizes surface charges on the suspended solids (colloids).
Projects
Figure 1 - Waste waterWater treatment using electrocoagulationTreatment
When the electrons destabilize the surface charges on these suspended particles, the metal ions, along with the hydroxyl particles form complex compounds called flocs that includes metals and other contaminants. Colloids and emulsified oils combine with these flocs to form sludge. Depending on the chemical composition of the floc, the sludge can either rise to the top and float or sink to the bottom. Sludge can be removed physically from the sludge tanks and disposed off in an eco-friendly manner.
The water is now available for further filtering or reuse.
Flocculation
The process of water filtration also involves a process called flocculation. This process is usually done before the water is released into the electrocoagulation unit. Flocculants are chemicals that are added to contaminated water to form flocs and sludge.
