Product description

Frequently asked questions

How do you maintain the GeoTrap filter?
For seasonal use at a cottage, the mass in the GeoTrap filter should be replaced once a year. After disconnecting the filter from the hoses, you can empty the entire contents into a compost. Then place the filter back in position and pour in a new bag of nutrient-binding mass.

Why can’t urine from a separating toilet be directed into the GeoTrap filter?
The excess liquid seeping through a composting toilet, called leachate, contains fewer nutrients than urine separated directly at the seat. The GeoTrap has not been tested for treating pure urine, which is much more nutrient-rich, and therefore it is not recommended for binding the nutrients from urine.

Manuals and files

Purify leachate with Dry Toilet Filter

GeoTrap Dry Toilet Filter is used to purify the leachate coming out of a composting dry toilet. The purification is based on special GeoTrap mineral which has been developed by Åbo Akademi, Finland.

Place the filter to the backside of the toilet

The most natural place for the dry toilet filter is at the back of the toilet. You may dig the filter partially into ground or leave it on ground totally. Just make sure it easy to service one a year when the minerals need to be changed.

GeoTrap mineral absorbs nutrients

The purification mechanism is based on GeoTrap mineral that absorbs nutrients in to itself hence preserving them from polluting e.g ground water. Used mineral can easily be reutilized in a compost.

Leachate outflow

We recommend leading the purified liquid for example to roots of a large tree or bushes, because plants can detach the nutrients from the mineral with enzymes and hence reuse the nutrients.
