GeoTrap Dry Toilet Filter purifies the seap liquid of a composting toilet with GeoTrap Nutrient Trap mineral. GeoTrap Dry toilet filter makes the use of a composting toilets easier as there is no longer need to collect and treat the seap liquid separately.
GeoTrap Dry toilet filter is designed to purify the seap liquid of composting toilets. The purification of GeoTrap Dry toilet filter is based on GeoTrap Nutrient Trap mineral which absorbs nutrients (eg. phosphorous and nitrogen) from the seap liquid. The purified liquid can be led to ground. GeoTrap Dry toilet filter is an excellent accessory to all composting toilets.
Please note, that GeoTrap Dry toilet filter is not suitable for urine diverting toilets. Also, when using the GeoTrap Filter, the outflow hose should not be lead straight to water (or any well, bond, ditch etc.) but to ground, preferably to large trees or plants.
In seasonal private holiday home use, the filter mass should be replaced once a year. In public use, the filter material must be replaced 1-3 times a year depending on the use of the toilet.
The used filter mass can be composted or it can be used directly as fertilizer to ornamental plants.
If the composting toilet is not used during the winter, the GeoTrap Dry Toilet Filter can be left in place and allowed to freeze without causing any damage. In the spring, the filter will thaw, and use can continue as usual, unless it is time to replace the filter mass.
However, if the toilet is used regularly during the winter, the filter should be insulated with insulation boards on the sides and top. Insulating the liquid hose is not necessary, as it will empty itself of liquid in any case.
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.

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.

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.

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.

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.
