Each system is custom engineered for site-specific needs using proven lightweight and durable Polymer Coated Steel (PCS). The system operates under gravitational and hydrodynamic forces with no moving parts which simplifies the treatment process. The standard Bio-Filter system utilizes... - Page 4 4 x 4 feet to 8 x 8 feet (16 to 64 square feet). An optional cylindrically shaped Bio-Filter model uses an external bypass structure(s) in lieu of the internal bypass, having similar surface areas as the standard models.
