Aquatron Composting Toilet System
Why Choose the Aquatron Composting Toilet System?
The Aquatron Separator technology uses the momentum of the flushing water, centrifugal force, and gravity to separate liquids from solid waste in the toilet flush water. There are no moving parts, no chemicals, and no electricity in the separation process.
The Aquatron Separator is combined with the Bio Chamber to achieve the performance and hygiene of a flush toilet system – with the ecological and environmental characteristics of a composting toilet system.
Easy composting
No smells, no chemicals, no power needed
Customisable to your needs
The best of both worlds
Low, easy maintenance
Highest quality standards
Innovative Composting Toilet System
Aquatron is an innovative composting toilet solution that’s suitable for all kinds of uses, especially where it is not possible to have a vacuum truck to empty your sewer. Thanks to the efficient separator technology, Aquatron makes it possible to have typical flushing toilets anywhere. Aquatron is an essential component of an eco-friendly waste system.
The Aquatron composting toilet system uses a Bio Chamber, which allows a homeowner to manage the composting process without having to come into contact with any waste material – simply rotate the container’s inner chamber to the next compartment, and you’re done!
The Aquatron composting toilet system can be scaled for everything from holiday homes and apartments, to museums and public buildings. The patented and CE-labeled Aquatron separator design ingeniously separates liquid and solid waste for easy composting – all without moving parts.
Aquatron technology cannot be surpassed.
Patented Ecological Technology
The Aquatron separator is cutting-edge yet simple technology.
All Aquatron systems include the patented and CE-certified Aquatron separator, which separates the solid waste (feces and paper) from flushed water and liquid waste. Aquatron systems harness the moving energy of the flushing fluid with centrifugal force and gravity to separate solid waste from the liquid.
There are no moving parts and no electrical power source is needed.
Up to three toilets can be connected to the same separator and flushed simultaneously when using standard domestic flushing toilets. A larger Aquatron separator model can be installed to handle eight toilets flushing at the same time.
How the Aquatron Composting Toilet System Works
The Aquatron composting toilet system is used in combination with a conventional household toilet pan, preferably a low-flush (6-litre max.) and with a P-trap (a type of plumbing pipe).
We use a genuine Aquatron Separator made in Sweden and imported exclusively by us. In this unique, patented centrifugal separator, the solids (poop and toilet paper) drop down into the NZ-made Bio Chamber where the composting occurs, while the liquids are diverted to either a soakage field or join the grey water for further treatment.
The Bio Chamber has four rotating bins. When the first bin is full of solids the handle is turned so the second bin receives the solids. By the time the first bin is back beneath the separator and receiving solids again, the solids have composted down to just 5% of their original volume, with the help of compost worms.
The composted material only needs to be removed once a year at most – depending on climate and usage.

Patented Aquatron Separator
The Swedish Aquatron separator receives the waste from the toilet(s) inside the house.
Once the liquids and solids (poop and toilet paper) are separated, the solids fall into the Bio Chamber where the composting process begins.

How the Aquatron Separator Works

Highly Efficient Bio Chamber
When worms are used, the Bio Chamber can reduce the volume of solid waste by up to 95% – making the removal of decomposed material a very minimal effort.
