To increase energy efficiency and reduce the quantity of sludge
operational area | usage
- Municipal / industrial wastewater treatment for up to 10,000 PT (total number of inhabitants and population equivalents)
- In combination with wks products for gas treatment and sludge thickening / sludge dewatering
- Optimised design and construction adapted to the plant size
- This compact digestion tank, can be provided in either round or an oval in shape
Technology | Process
- Mesophilic sludge stabilisation of dewatered sludge
- 15–25 days retention time, depending on the plant size and sludge characteristics
- Tank stirring is carried out eighter by use of a digestion tower mixer, or by gas injection
- Foam trap for protecttion of the gas system
- Plant-specific gas treatment and gas recovery
- Process and control engineering optimisation of the wastewater treatment
- Particular attention is paid to the energy-effectiveness of the anaerobic sludge treatment occuring thanks to the process changeover from simultaneous aerobic to anaerobic sludge stabilisation
Process Engineering Components
- Anaerobic sludge treatment technology consisting of:
- Detailed design of the process engineering, system engineering and EI&C technology
- Process-relevant equipment (circulation, gas treatment / gas recovery, etc.)
- Automation technology for optimisation of the effectiveness of the anaerobic sludge treatment taking into account the wastewater treatment
- Commissioning, optimisation, training, service
- Realisation of complete plant
benefits
- Improvement of the energy efficiency of the entire plant
- Significant reduction in sludge production
- Improved dewatering
