Biofilters
Biofilters are used for purification of wastewater with biological filters filled with naturally occurring microorganisms.
Wastewater is pre-treated in precipitation tanks and then pumped to biofilters. In biofilters, wastewater is thoroughly treated in biological filters, which are filled with biofilter materials of naturally occurring microorganisms.
Wastewater can be led to streams, ditches, drainages, etc. after purification.
Tunetanken biofilters meet the requirements of SO purification class (increased requirement for reduction of organic material) and O purification class (reduction of organic material). In addition of phosphorous removal to the system, it will meet the requirement of SOP purification class (increased requirement for reduction of organic material as well as nitrification and reduction of phosphorous) and OP purification class (reduction of organic material and reduction of phosphorous).
- Sedimentation tank.
- Pump well incl. pump part.
- Biofilter tank.
- Ventilation well.
- Drainage pipes.
- Meet the requirements of SO purification and O purification class and in addition of phosphorous removal to the system, it will meet the requirement of both SOP and OP purification classes.
- The wastewater’s organic materials and nutrients are metabolized.
- After purification the wastewater can be led into streams, ditches, drainages, etc.
