Zoetis has commissioned Corpi to carry out the installation of a microfiltration treatment system and an activated carbon filter to treat wastewater generated from the cleaning of reactors containing soluble organic compounds (DCM and GLPA).

The microfiltration filter is made of 316 stainless steel and contains 20 polypropylene cartridges with a filtration grade of 50 µm. Its function is to protect the activated carbon filter from the entry of solid particles. The water is then directed to the activated carbon filter, which has a diameter of 2600 mm and a cylindrical height of 5200 mm, with a total height of 7010 mm. The filter’s hydraulic capacity is 10 m³/h at a maximum pressure of 10 bar. The filter media consists of 10 tons of mineral carbon (MG900), chosen for its high efficiency and great porosity.

Water enters the top of the filter through a pipe that distributes it evenly across the surface. The flow moves downward until it reaches the bottom, where it exits through strainers that prevent the loss of activated carbon. The filter is equipped with manholes for inspection and maintenance, as well as pressure gauges and switches to monitor inlet and outlet pressure.

The treated water can then be discharged into the municipal sewer system or the factory’s own treatment plant, meeting quality standards.
