Water shields
Bringing together landscape art and closed loop ecosanitation.
Key features:
- Circularity.Nutrients and water reuse for agriculture
- Modularity/Modular design suitable for upscaling and context adaptation
- Sustainability. It is a real nature based solution for waste water treatment
- Resilence. Effective cold climate performance
- Biochar as main transport for nutrients recovery from waste water to soil
- Beauty.Beautiful landscape art
- Earthworms as waste water treatment boosters
- Inclusiveness. Solution for locations where centralized sanitation is not possible for various reasons
Water shilelds is a modular waste water treatment system that enables closed loop nutrients and water recycling and at the same time piece of beautiful landscape art. Due to heavy insulation it is able to perform its functions in every climate including very cold conditions maintaining above zero temperature to support water treatment biological processes.
Water shields system is usually installed as an aerobic secondary treatment step after septic tanks to work as a single pass or recirculation media filter. With some design modifications biopot modules can also be used as a primary filter without pre settling. The performance is further enhanced by source separation into black and gray water flows each of them treated by separate set of biopot modules totally as aerobic stage.
The active filtering substrate – biochar (charcoal) is used in biopot and The extracted biochar charged with nutrients and beneficial organisms then applied as soil amendment and fertilizer. In this way nutrients recycling is achieved- they are returned back to agriculture and the waste water becomes a resource rather than a problem to solve.
The performance of biofilter is enhanced by earth worms which feed on charcoal substrate biofilm and help maintaining aerobic conditions.
Water shields are followed by next treatment steps, usually constructed wetlands or ground infiltration systems . Due to biopot treatment their size can be significantly reduced. Water shields system can be added to the existing septic system and upgrade the effluent quality as well prolonging the lifespan of the leach field. Water shields modules can be used in sequence potentially treating waste water to a very high degree.
And they are beautiful. The artistically sculptured and painted water shields modules create landscape design compositions that brings art and beauty to our everyday life and environment.
