Waste Water Treatment
BAYER Ozonization System for wastewater and wastewater sludge
We offer...
... a high efficient system and the process know-how for the ozonization of wastewater and wastewater sludge.
The economical application of ozonization depends strongly on the effectiveness to bring gaseous ozone into the water / sludge matrix.
The Bayer Ozonization System consists mainly of the BAYER Injector System as the high efficient gassing system and a fully mixed activation vessel for the oxidation reaction.
In the BAYER Injector the kinetic energy of the propelling water drags gas into the injector, breaks the gas into small bubbles and pushes the water/gas dispersion into the activation vessel.
Application of Ozonization for Wastewater
Typical objectives for ozonization of wastewater are
- Removal of COD
- Adjustment of the COD/BOD ratio for further biological treatment
- Sanitization
- Removal of micro contaminations Depending on the objectives we provide one or two step ozonization
systems.
Application of Ozonization for Sludges
Typical objectives for the ozonization of wastewater sludge are
- Reduction of suspended solids
- Reduction of organic content
- Enhancement of sludge dewatering
- Generation of carbon-source for denitrification
- Reduction of bulking sludge
Depending on the mentioned objectives the ozonization step is placed in the return sludge cycle or the excess sludge path.
Example for the ozonization of aerobic excess sludge
- TSS elimination 10 – 95 % (normal 40 – 50 %)
- Complete substitution of external carbon source with DOC in effluent of the ozonization system
- DOC in effluent of ozonization system as control factor for the operation of the ozonization system (Patented EP1763491)
