Ecotechnologies China
Blumberg
Engineers represent a consortium of German-Chinese
companies for ecotechnology applications for water, wastewater and
sewage sludge treatment by constructed wetlands.
- Constructed
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.
- Reed 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 agricultural reuse.
- Stormwater treatment wetlands
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.
- Wetland
roofs
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 advantages.
- Natural swimming pools
Natural swimming pools have aesthetic appearance with planted
soil filters for water regeneration and need no chlorine
treatment.
- Floating
islands
Floating islands are artificially produced buoyant marsh plant
carriers for water cleaning purposes and provide breeding
habitats for fishes and birds.
- Landfill 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.
- Activated sludge process
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.
- Wetland
garden
Our innovative wetland garden concept comprises a
demonstration center for sustainable ecotechnologies combined
with features of a recreation park for the public.
We are looking for clients, who would like to realize this
green ecological center.
