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 a60°. homogeneousThis mixtureallows offor water,the oil,solid vegetablewaste juice,to soil,slide meat,into andthe alcohol.incineration chamber.

A high=powered propane incinerator burns the solid waste.

Method

 

An 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:

1. From the anode, metallic ions are released into the contaminated water.
2. On the cathode, water is hydrolyzed, forming hydrogen gas (H₂) and hydroxyl (OH) particles.
3. Electrons move from the cathode to the anode. This destabilizes surface charges on the suspended solids (colloids).

 

Figure 1 - Waste water treatment using electrocoagulation

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.
