TETRA® DeepBed™ Gravity Filtration SystemSource: De Nora Technologies
Severn Trent Services offers the TETRA® DeepBed™ gravity filtration systems to achieve superior solids capture deep with a 6-foot media bed. The unique advantage of the TETRA DeepBed system is the retention of solids throughout the media bed, rather than the surface screening which occurs in most other deep bed filter systems. Flow rates up to 10 gpm/ft² can be handled without breakthrough or bypassing. TETRA DeepBed filters can achieve effluent turbidities of 1 Nephelometric Turbidity Units (NTU) or less and effluent suspended solids of less than 5.0 mg/L total suspended solids (TSS). The long run times and low maintenance costs associated with the TETRA DeepBed system make it an ideal choice for tertiary treatment.
