Root systems

Root systems are used for wastewater purification. Wastewater is pre-treated in precipitation tanks and then pumped to root systems.

In root systems, wastewater is treated through a gravel filter, which is planted with reeds or similar plants. Microorganisms on plant roots or grains of sand converts the organic material and nutrients of wastewater.

After purification, wastewater can be led to streams, ditches, drains, etc.

Tunetanken root systems meet the requirement of purification class O (reduction of organic material).
