SBR-Constructed
Wetlands
The SBR-Constructed
Wetlands is a combination of a sequencing batch
reactor (SBR), reed bed treatment and sludge dewatering system in one
construction. The SBR-system is based on the conventional aeration
system for wastewater treatment (activated sludge process). The
different processes: Mixing (denitrification), aeration (carbon removal
and nitrification) and settling takes not place in different chambers
but in a firmly defined cycle in only one chamber. The processes are
running one after another in three phases: Filling, reaction,
sedimentation.
After the complete treatment the
clarified
water will
be discharged into the reed bed treatment system as a polishing
treatment step and for disinfection. This water leaks through the
sandfilter and then flows into an special storage tank under the reed
bed treatment system. The stored clean water can be used for irrigation
or discharged into a river. The accumulated sludge gets into the sludge
dewatering reed bed beside the SBR-reactor.
