Thanks to the over ten years experience gained in the air treatment, the Depur Systems has developed an active carbon filter for the control of odor emissions originated in the lifting stations and wastewater in the tanks (tank) of storage of some wastewater requiring an odor abatement during during loading and unloading. These filters are equipped with a filter cartridge containing granular activated carbon, suitably supported by a layer of synthetic fabric and a metal mesh. The vapors (emissions) that originate during the handling of the fluid inside the tank (loading or unloading) are adsorbed by the filter which allows the control of air flow in both directions. In sewage lifting stations or units of biological treatment, monitor emissions into the environment unpleasant.
