Run your digester safely and reliably
Improve your operational costs and optimize the energy balance of your plant
Globally there is a strong movement towards sludge treatment in the waste water industry. The main reason is stricter local legislation which forbids sludge discharge into the environment (bodies of water, fields). Therefore, sludge becomes a remarkable cost factor for plant operators. Sludge digestion can offer cost advantages by reducing sludge quantity by around 50% while also providing a valuable energy source – biogas.
Anaerobic bacteria need stable process conditions
In the digester process, the bacteria have to be protected against critical process conditions. This means the process control has to guarantee the following:
Constant temperature and nearly neutral pH value
Darkness and absence of oxygen
Harmonized load of the process
Sufficient retention time
Monitoring of biogas production
Basic control parameters are inlet flow of the sludge, level, temperature and optionally pH measurement in the digester, and the flow and methane concentration of biogas.
