In livestock slurry treatment, cow or pig slurry is collected, mixed and sent to a screw separator.

Inside this separator the slurry is compressed by a screw as it passes through a cylindrical filtering sieve with longitudinal slots. The screw transports the solid material to the machine exit while the liquid material flows into the body of the separator through the longitudinal slots. At the end of the livestock slurry treatment, the solid material is used for composting or to produce bedding materials, while the separated liquid is used as field fertiliser.

The VICO-Screen® filtering sieve is a high-quality wedge wire screen. It is made from stainless steel so that it does not require special maintenance. The arrangement of the openings minimises the risk of clogging and thanks to the high open areas, filtration occurs efficiently even at high capacity. Costacurta can supply it as a finished cylinder, manufactured according to clients’ specifications.
