History & team

AQUA TERSUS WATER REGENERATION SYSTEMS is a Swedish Company providing lasting onsite products and solutions for biological treatment of wastewater and polluted water, respectively water re-use and restoration of heavily polluted freshwaters.

AQUA TERSUS is located at the Ideon research park in Lund, Sweden. The company capitalizes on decades of scientific research and interdisciplinary experience in international water projects. We have several partnerships and collaborations, and are members of the Water Innovation Accelerator and the Blue Economy networks. Through cumulative knowledge and front edge competences in its team, AQUA TERSUS provides lasting solutions based on closed-loop ecosystems that improve local access to water while contributing to restoration of degraded ecosystems.

AQUA TERSUS offers a family of products: ReVive™, ReMulti™, ReGreen™ and ReFine™. All our products are manufactured in Sweden in cooperation with certified local specialized industrial manufacturers. The ReViveTM system has been until now installed in over 300 locations across France, Poland, China and Sweden.



Our motives

Water is life. More than 2.3 billion people live without access to basic sanitation facilities. Growing urban populations and deterioration of water resources puts increasing pressure on shrinking freshwater resources.

Besides humans, the shortage and pollution of freshwaters targeted hundreds of species living in natural habitats. With almost half of the global vertebrates distributed in terrestrial, freshwater and marine habitats extinguished, the state of natural ecosystems has never been that alarming!

These negative impacts accelerate the search for innovative and cost-effective solutions. Reclaimed water has to be used in the most sustainable way because it alleviates the burden of increased water demand due to growing populations and subsequent food production.



Our approach:
A paradigm shift

Aqua Tersus adopts a new paradigm in tackling the water issues, a holistic approach that can be summarized by three key words: Onsite solutions, Natural processes and water reuse.

1 Onsite (decentralised) solutions:

The problems have to be solved at their source avoiding conventional solutions built on massive infrastructures (sewerage and connection pipes) and multiple processes (mechanical, biological and chemical).

2 Natural processes:

Our solutions are based on natural processes through bio-mimicry. Nutrients (in different forms: organic, inorganic, gaseous, ionic) are being cycled within the created ecosystem and their return to the soil is guaranteed by water-born insects, thus creating a unique “closed-loop” solution.

3 Reuse of water:

In our dictionary, the purified water should always be reused and when free from nutrients should return to the ground or be reused for different purposes (watering, washing, etc.).




Our team of experts combines scientists with dozens of years of experience in corporate research and international interdisciplinary projects. The internal team consists of scientists in the fields of limnology, plant physiology, applied microbiology and biotechnology. The team is expanded through external collaborations to cover the fields of hydrology, electrical engineering and landscape architecture. We are members of the Water Innovation Accelerator, Ideon Science Park, Lund, Sweden.
