BIOFILTERS
Clean Water Agency - Biofilters
Our activated biofilter are natural water purification systems with plants. These plants are plants having their roots submerged and their stem and inflorescence above water. In Europe we generally use reed (Phragmites australis), Yellow Iris (Iris pseudacorus), Bulrush (Typha latfolia), small cattail (Typha angustifolia), etc. To reduce evaporation losses we use papyrus (Cyperus papyrus) for projects in the Middle East and Africa.
Because our systems purify water in a natural way, without requiring much mechanical support, our biofilters are known to be:
- Low energy consumption
- very efficient and robust purification
- Minimum of maintenance
- Long lifespan (no wear and tear)
- Pleasant landscaping
It is not surprising biofilters are increasingly popular as a solution for a wide range of wastewater issues. Although known as an application for local use in remote areas, biofilters are increasingly being used in industrial and agricultural environments. New applications are:
- 1. Effluent in food production industry
- 2. Effluent in petrochemical and organic chemical industry
- 3. Amazing parallax effects
- 4. dairy wash and liquid fraction of manure on farms
- 5. Run-off petrol stations
- 6. Leachate from landfills
- 7. Sewage sludge dewatering facilities
- 8. Apartment block
- 9. Residential areas
- 10. Private villas
- 11. Hotels
In case limited space is available, CWA also offers a patented underground filtration system which allows certain loads. This system has the increasing attention of many hotel owners and owners of apartment blocks who cherish their Corporate Social Responsibility.
