BIOFIL toilet system is a technology that works by providing an enclosed environment for natural process of aerobic decomposition of feces including toilet paper and degradable materials. The digester is constructed as a living filter where oxygen inflow into the vault allows the seeds (bacteria, fungi, macro-organisms) within to degrade solids at the top layer aerobically and liquid are filtered into the lower layers before being directed out of digester through a pipe into constructed drain field or collected and treated for reuse. This technology operates by:
**Rapid separation of solid and liquid;
**Aerobic decomposition of solid;
**Bio- filtration of waste water.
This is the same type of environment in forest where wildlife droppings are decomposed and converted into valuable nutrient for vegetation.
