Solviva's flush toilet composting filter

Postby blimpyway » Thu Jul 19, 2007 12:23 pm

I found this composting/filter that is claimed to handle 1.6gal/flush toilet water.
It uses worms and has a rather large volume.
Another amazing claim is that in 25 months of usage the level of compost did not raised, but it diminished instead from the initial 12 cuft of leaves and sawdust to 9 cu.ft.
It also acts as a biofilter, reducing BOD and amonia from the flushed water to 80-90%
Here-s the page http://www.solviva.com/wastewater_book.htm
(Go page down until reaching the paragraph titled:
THE SOLVIVA COMPOSTING FLUSH TOILET )

Any opinions?

Very interesting.

At first glance (without having read all the details) it looks like a greatly upscaled version of Jenkins' humanure buckets. Lots of carbon!

As always, the devil is in the details. I need to read her book!

If there can be found a way to prevent worm compost bin to become anaerobic when significant amounts of toilet water are flushed through it, while stopping 80-90% of BOD and >50% of amonia, then it could become a great way to minimise wastewater treatment expenses.

Followed by a small wetland could it produce high quality effluent?

P.S. Here-s a company and their acompanying patent for worm & beetle compost-treatment of wastewater:

Most interesting product.

I'm impressed not only with the idea, but with the marketing. Using humus which "turns the problem (the waste) into the solution (the humus to filter and clean the wastewater)" is rather similar to the way I use sludge as a filter media in my graywater treatment unit.
