ACT® wastewater treatment plant

Microorganisms and aquatic plants purify water by feeding on different substances. In ACT® these natural processes are optimized to treat the wastewater requiring only 3 m2 of the garden.

Robust biological processes – low maintenance

Since ACT® is based on natural processes it requires close to no maintenance and no supply of chemicals which saves you both time and money. Thanks to our unique sludge degrading system sludge removal is put to a minimum (approximately every 10th year).

The microorganisms and plants adapt automatically to variation in wastewater load, meaning that no adjustments are needed once everything is installed.

All users, from small households to large facilities such as hotels, benefit from using ACT®. It can easily be upgraded to manage larger loads of sewage or tougher treatment requirements.

ACT® has an outstanding ability to take care of unwanted substances. Tests carried out by the Swedish Environmental Research Institute show that ACT® purifies the water from pharmaceutical residues better than average municipal wastewater treatment plants.

  • Secure and reliable
  • Long lifespan
  • No costly chemicals or service needed
  • Minimized need for sludge removal

How does it work?

ACT® treats the wastewater in one to three steps depending on the circumstances at your property.

In the first step, ProACT®, microorganisms are degrading the sludge. Thanks to special structures in the tank, there is a lot of surface for microorganisms to form biofilm (their home). The oxygen level in the tank is low. These factors combined result in degradation of the sludge which minimizes the need for sludge removal. Approximately one sludge removal every 10th year is needed.

From ProACT® the wastewater is pumped to InterACT® where it is exposed to other types of microorganisms and to natural aquatic plants whose root systems also make up a good environment for the microorganisms. The plants as well as the microorganisms feed on nutrients in the wastewater.

In some cases, an additional treatment step, ReACT®, is required to achieve extra reduction of phosphorus to prevent eutrophication. In ReACT® phosphorus is bound to a lime material. When the filter material is saturated with phosphorus it can be spread on farmland as a fertilizer.

ACT® is a very robust system requiring electricity only to power a water pump and an air pump. A micro-computer together with a static level meter in ensures stable operation and monitoring of the system.
