Low operating costs and no filters to replace. Places systems directly in the area of greatest contamination and allows scale up as needed. Cartridge design allows maximum flexibility in process design. The spiral flow reduces channeling effects and offers a low pressure drop. Provides large surface area for biodegradation in a small space.
Treats groundwater in place with subsurface systems.
Heavy metals are trapped on the bacteria for reuse, recycling or resale. Treats contaminants in water and air simultaneously. For more applications, see the Industrial Emission and Water Treatment overviews. CWP systems may be placed above ground or below the ground's surface to treat groundwater in place. In addition to encountering fewer permitting requirements, this option consumes less energy because the water is not pumped to the surface for treatment.
