Technics

Bacteria that are allowed to grow as a biofilm on a carrier can be kept in the system for longer. The resulting biofilm serves to treat the water.

In a sludge drying installation we dry sludge from water treatment plants. The dried sludge can then serve as a secondary fuel. The sludge can be dried at low temperature with locally available residual heat. In this way, energy can be transported via dried sludge and put to use in a high temperature setting.

Odour nuisance can occur when treating industrial waste water or processing sludge. Concentrations of substances like H2S or NH3 can be so high as to become life-threatening.
