Biofiltration is a biological wastewater treatment technology used in municipal, steel, and chemical manufacturing facilities, solid waste processing plants, composting operations, and rendering plants. Biological systems use microorganisms that consume and destroy organic compounds as a food source.
Severn Trent Services offers biological filters and wastewater treatment systems for applications that require treatment including removal of BOD, ammonia, suspended solids and nitrate-nitrogen. The major benefits of this system are that it allows a sewage treatment installation in nitrogen sensitive areas, where a conventional system may not be allowed.
