Aquatron Eco Toilet System
Aquatron International AB
The Aquatron is an ecological, composting toilet system which can be connected to ordinary toilet to process waste.
The Aquatron is an ecological toilet system which treats waste after being connected to ordinary toilets. The system does not require electricity, chemicals or moving parts, instead using the momentum of the flushing water to separate urine from feces and paper. The urine is treated either by a UV device or phosphorus trap to meet the standards of grey water, and then is infiltrated into the soil. The solid waste is composted in a bio-composting chamber and then can be used as compost.

Goal 6: Clean Water and Sanitation
Households using decentralized systems, households without electricity
The systems are made entirely of plastic, both recyclable polyethylene and glass-reinforced polyester. When configuring the system, it should be located between 32 inches and 200 feet from the toilet and sloped between 1-5%. The Aquatron can be installed in various configurations (shown below), depending on the specific application.

The Aquatron ecological toilet system was designed to be easily integrated into existing, common toilet systems. The separator is configured without moving parts and does not require additional energy, instead using the momentum of the flushed waste to separate water from feces and paper. Various composting chamber sizes are available depending on the scale of usage; the systems can accommodate from a single family to an entire apartment building.
Technical support is provided by the manufacturer, with recommendations to replace the UV lamp after 4-5 years and the phosphorus trap after 1 year.
Replacement components can be purchased from the manufacturer or retailers.
With regular maintenance, the manufacturer estimates a life span of 50 years for the Aquatron.
The manufacturer specifies performance targets related to no capacity limit on toilet usage, no required discharging of black water or sludge, and an economical operation of toilets.
The system was designed to ensure that users did not have contact with unsanitary human waste.
The standard Aquatron toilet system can be coupled with either a UV lamp or a phosphorus trap to further treat separated urine and water.

The Aquatron toilet system can be coupled with UV or a phosphorus trap to further treat wastewater, if required by local regulations. In addition in accordance with regulations, the composted materials emptied from the Aquatron 50, 2×50 and 90 must continue the composting process with normal garden or kitchen waste, while the models 4×100, 4×200 and 4×300 require no further composting.
