The humus filter
The key to efficient treatment
Worms and many other organisms quickly convert the solid waste into humus, one of the most powerful components of the BioPod.
The humus is like a rich organic top soil. Worms and beetles continually burrow through it and keep it open, free draining and aerobic. They maintain it in a sponge-like structure, with many kilometers of oxygenated tunnels. It is this large surface area that aerates and cleanses the wastewater as it trickles through.
This humus filter ensures:
- no potentially smelly anaerobic septic stage (humus absorbs odour)
- natural aeration - no mechanical aerators needed
- robustness - unlike many water-based mechanical systems, any accidental chemical spills do not quickly spread throughout water, killing a large number of organisms. Instead, they are isolated in a small section of the humus, where only some organisms may die, and the others can safely recolonise the area as required
It may be doubted whether there are many other animals which have played so important a part in the history of the world than the worm".
