Biological waste water treatment units
Unit for BOD reduction
Wärtsilä Senitec AB offers a complete range of biological waste water treatment systems for power plants.
The design for each power plant is a tailor-made solution. Depending on the effluent and required
discharge standard the total solution is made.
The BS unit is a modified trickling filter over a clarifier that reduces biochemical oxygen demand
(BOD5) and total suspended solids (TSS) to levels that meet or exceed NSF and EPA standards.
A modular technology, BS units natural fixed film biological process is a cost-effective system for
the secondary treatment of wastewater. Units can be installed in parallel to treat larger flows or
in series to achieve greater levels of treatment.
