represent a consortium of German-Chinese companies for ecotechnology
applications for water, wastewater and sewage sludge treatment by
wetlands for domestic and industrial wastewater treatment
Constructed wetlands comprise artificially engineered wetland
ecosystems for wastewater and sludge treatment. They utilise particular
combinations of aquatic plants, soils and bacteria (in lined basins) to
optimise the physical, chemical and microbiological processes naturally
present within the root zone of the marsh plants.
bed sewage sludge treatment
Reed bed sewage sludge treatment is a natural sludge processing method
for gravity dewatering, mineralization of organics and
evapotranspiration induced by reed plants (Phragmites australis).
This ecotechnology works without chemical additives like polymers for
conditioning and results in sludge humus which can be recycled for
Stormwater treatment wetlands (retention soil filters) are used for the
purification of polluted rainwater of combined sewerage systems
(stormwater overflows) and of paved areas like streets.
- Industrial wastewater treatment
Treatment of tapioca processing industrial wastewater in Southern Vietnam.
A wetland roof is a special type of extensive green roof. A roof is
evenly planted with wetland or marsh plants which will be regularly
irrigated on a daily basis. Besides the aesthetic aspect, this
particular type of roof may also offer significant functional
- Biological air cleaning system (BACESS)
The root zone system BioVentic is an air treatment system based on light soil filter with vegetation.
Natural swimming pools have aesthetic appearance with planted soil
filters for water regeneration and need no chlorine treatment.
Floating islands are artificially produced buoyant marsh plant carriers
for water cleaning purposes and provide breeding habitats for fishes
leachate treatment by constructed wetlands
The leachate from solid-waste landfills contains toxic organic
compounds, nutrients, organic carbon and heavy metals. Constructed
wetlands have been operating successfully in treating these
effluents in different parts of the world.
Wastewater is aerated and metabolized by suspended microorganisms. The
new microbial cells formed are removed in a final settling tank from
the liquid as excess sludge. We often use constructed wetlands behind
conventional wastewater plants for tertiary treatment and sewage sludge
dewatering and mineralization of organic matter.
Our innovative wetland garden concept comprises a demonstration center
for sustainable ecotechnologies combined with features of a recreation
park for the public.
